SPICE-Aided Models of Magnetic Elements—A Critical Review

This article analyzes the problem of modeling the properties of such magnetic elements as inductors, coupled inductors, and transformers using the SPICE software (version 17.2). Both the classical models of magnetic elements, built in this software, and the models implemented in the form of subcircuits are described. In particular, attention was paid to the possibility of taking into account the non-linearity of the characteristics of the considered elements and mutual couplings between electrical, magnetic, and thermal quantities. Using the results of thermographic measurements, the need to take into account the differences in temperature values between the individual windings and the core of inductors and transformers was justified. Selected models of the considered elements given in the literature are briefly characterized. The network structures of the electrothermal models of the considered elements elaborated at Gdynia Maritime University are presented. The results of calculations and measurements illustrating the correctness of the described models and their prac-tical usefulness for the elements of different structures are presented and discussed.

Characterization of Instrument Transformers under Realistic Conditions: Impact of Single and Combined Influence Quantities on Their Wideband Behavior.

Instrument transformers (ITs) play a key role in electrical power systems, facilitating the accurate monitoring and measurement of electrical quantities. They are essential for measurement, protection, and metering in transmission and distribution grids and accurately reducing the grid voltage and current for low-voltage input instrumentation. With the increase in renewable energy sources, electronic converters, and electric vehicles connected to power grids, ITs now face challenging distorted conditions that differ from the nominal ones. The study presented in this paper is a collaborative work between national metrology institutes and universities that analyzes IT performance in measuring distorted voltages and currents in medium-voltage grids under realistic conditions. Both current and voltage measuring transformers are examined, considering influence quantities like the temperature, mechanical vibration, burden, adjacent phases, and proximity effects. The study provides detailed insights into measurement setups and procedures, and it quantifies potential errors arising from IT behavior in measuring distorted signals in the presence of the various considered influence quantities and their combinations. The main findings reveal that the temperature has the most evident impact on the inductive voltage transformer performance, as well as the burden, causing significant changes in ratio error and phase displacement at the lower temperatures. As for low-power ITs, establishing a priori the effects of adjacent phases and proximity on the frequency responses of low-power ITs is a complex matter, because of their different characteristics and construction solutions.

PurposeThe purpose of this study is to create an extended equivalent circuit model for a compound DC motor, consisting completely of electrical parameters and quantities.Design/methodology/approachThe dynamic model of the compound DC motor is obtained by establishing the voltage equations for the armature and excitation circuit and the mechanical equation for the mechanical part. The mechanical parameters in the dynamic model are converted into electrical parameters with an electrical circuit proposed for the mechanical part. By combining the armature and excitation circuits with the electrical circuit created for the mechanical part, the extended equivalent circuit model of the compound DC motor is obtained. Because the proposed extended equivalent model is completely an electrical circuit, simulations can be made in the circuit simulation programme. Simulations of the proposed compound DC motor circuit were carried out, and the accuracy of the proposed circuit was verified by performing experimental studies with an existing compound motor.FindingsWhen comparing speed and current profiles in experiments and simulations, it is seen that compound DC motor can be modelled with the proposed equivalent circuit including completely electrical elements in a simulation programme for the circuits. The results show that the proposed equivalent circuit satisfies the dynamic model of the compound motor.Originality/valueIn DC machine models, armature and excitation circuits are given as an electrical circuit, and mechanical part of the machine is modelled by only mechanical equations. The originality of this study is converting the dynamic model of an electrical machine consisting of electrical and mechanical equations into a completely electrical circuit. With the proposed method, the dynamic model of many motors can be converted into a completely electrical circuit. In this way, motors can be simulated as an electrical circuit in simulation programmes for the circuits, and the dynamic behaviour of motors can be obtained.

ELECTRICAL PROPERTIES OF ZnO(x)–Co3O4(1−x) (x = 0.7, 0.5, 0.3) OXIDE THIN FILMS VIA FOUR POINT PROBE DEVICE: SUBSTRATE TEMPERATURE EFFECT ON THE ELECTRICAL PROPERTIES

ZnO[Formula: see text]–Co3O[Formula: see text]([Formula: see text]= 0.7, 0.5, 0.3) oxide thin films were synthesized via spray pyrolysis deposition. The obtained films were investigated to find the surface electrical resistance ([Formula: see text]) and conductance ([Formula: see text]) using the four point probe device and the Van der Pauw mathematical relation to estimate the electrical resistivity ([Formula: see text]) and conductivity ([Formula: see text]). In addition, the electrical resistance, conductance, resistivity and conductivity were obtained. From the obtained results, we have observed that the electrical quantities of the nanocomposite films are close to the interval bounds of the electrical quantities of the pure materials. For example, at room temperature, the electrical resistivity values of ZnO, Co3O4, ZnO[Formula: see text]–Co3O[Formula: see text], ZnO[Formula: see text]–Co3O[Formula: see text] and ZnO[Formula: see text]–Co3O[Formula: see text] were found to be around 6.89 × 10[Formula: see text], 1.58−103, 339.75, 611.55 and 1333.632 Ω.cm, respectively. This note can be depending on the density (concentration) of the carriers (electron/holes) of the constituents (pure material) of the composite material. Besides, the variations of these quantities were measured as a function of the substrate temperature. It was found that the conductance and conductivity vary proportionally with the temperature, but the electrical resistance and resistivity were inversely proportional. This remark indicates a semiconducting electrical behavior. The possible reaction mixture of pure semiconductors materials in the synthesis process is explained. The studied semiconductor oxides show interesting electrical properties, which makes them potential candidates to be used in various optoelectronic devices.

Study on sound transmission characteristics and positioning strategy of gas insulated transmission line shell

Gas insulated transmission line (GIL) is widely used for large-capacity power transmission in complex environment, and has the characteristics of long distance and totally enclosed structure. When the insulation fault occurs inside GIL, its metal shell structure makes it more difficult to monitor through optical, electrical and other physical quantities. Considering the rapidity and accuracy of positioning, the propagation of sound waves along the GIL sheath is a commonly used method in GIL on-site PD testing and running state online monitoring for fault positioning. This paper establishes a high-pressure GIL acoustic propagation simulation model based on pipe acoustics theory, analyzes the frequency dispersion and mode distribution of acoustic waves along the GIL shell, determines an appropriate fault location strategy based on the propagation velocity and attenuation of the selected acoustic wave mode, and carries out experiments to verify it. The results of the research show that the low order bending wave F(1,1) propagated along the GIL shell has good positioning characteristics, and the propagation velocity conforms to the dispersion curve distribution. By taking into account the attenuation and delay of the acoustic wave passing through epoxy insulators or expansion joints in the fault localization strategy, the localization accuracy can be improved by 60%. And this positioning strategy was verified to be effective in the GIL insulation fault localization test conducted in the field.

A Line Loss Separation Method Based on Topology-aware Correlations and Nonlinear Impedance

Due to the varying order and hierarchical relationship of different meters on the same line, the variation pattern of line loss and electricity consumption is not obvious, making it difficult to separate them accurately. To address this issue, an innovative method for line loss separation based on topological relationship perception and nonlinear impedance is proposed. Firstly, based on the topology recognition algorithm, we identify the order of the electricity meters and the relationship between the father and child-level electricity meters. Then, using the principle of topology relationship, we accurately measure the impact of the father and child level electricity meters on the overall line loss electricity quantity. Combined with data difference and matrix difference methods, the fixed loss value is offset. On this basis, a sliding window method is used to draw the curve change of nonlinear impedance and loss of electricity quantity. By analyzing the approximate continuous relationship between electricity consumption and line loss rate through curves, the line loss electricity consumption can be effectively separated. The results indicate that the proposed method has a better performance compared to other methods.

A scalable electronic analog of the Burridge-Knopoff model of earthquake faults.

The Burridge-Knopoff model implements an earthquake fault as a mechanical block-spring chain. While numerical studies of the model are abundant, experimental investigations are limited to a two-blocks, analog electronic implementation that was proposed by drawing an analogy between mechanical and electrical quantities. Although elegant, this approach is not versatile, mostly because of its heavy reliance on inductors. Here, we propose an alternative, inductorless implementation of the same system. The experimental characterization of the proposed circuit shows very good agreement with theoretical predictions. Besides periodic oscillations, the circuit exhibits a chaotic regime: the corresponding markers of chaoticity, namely, the correlation dimension and the maximum Lyapunov exponent, were experimentally assessed to be consistent with those provided by numerical simulations. The improved versatility and scalability of the circuit is expected to allow for experimental implementations of the Burridge-Knopoff model with a large number of blocks. In addition, the circuit can be used as the basic element of scalable platforms to investigate the dynamics of networks of oscillators and related phenomena.

Monitoring Method for Off-grid Capacity of Direct Drive Wind Farm

A direct drive wind farm (DDWF) is composed of multitudinous permanent magnet synchronous generators (PMSG), with a small single-unit capacity. When the power grid mal-functions, some units in the DDWF may enter a fault traversal state, and some units may be disconnected from the grid. At this time, the DDWF exhibits a decrease in active output. Due to the large number of units in DDWFs, it is difficult to directly monitor each off-grid unit, resulting in the inability of the power grid to timely and accurately determine the load shedding amount. This article proposes a monitoring method for the disconnection capacity of DDWFs, which can calculate the disconnection capacity of DDWFs after a fault occurs by only monitoring the electric quantity at the connection point of the DDWF. And a DDWF grid connection model is built using PSCAD simulation software. The reliability of the monitoring is authenticated through simulation using a single-phase grounding short circuit fault as an example.

In order to solve the technical problems of traditional power system classic formulas that are difficult to explain the static stability limit changes of power grid interconnection lines, as well as the difficulties in improving and warning the static stability limit power of interconnection lines, this paper provides a method for improving and warning the static stability limit of power grid interconnection lines. Firstly, based on the electrical quantities measured by the wide-area measurement system (WAMS) of the power grid, the equivalent reactance of the power grid interconnection lines, and the equivalent impedance from the high voltage side and medium voltage side of the three coil transformers on both sides of the interconnection line are determined. Secondly, under pre-set operation mode and constraint conditions, the configuration quantity and capacity of the dynamic reactive power sources on the medium voltage side of the three coil transformers on both sides of the interconnection line are determined. Finally, based on the determined configuration and pre-set operation mode of the dynamic reactive power sources on the medium voltage side of the three coil transformers on both sides of the interconnection line, the historical electrical quantities measured by WAMS. The static stability limit and static stability margin of the interconnection line are calculated, and warnings are provided.

Многофакторное автоматизированное исследование методов определения места повреждения на модели воздушной линии электропередачи 500 кВ

Fault location is one of the main means of automation of electric power on overhead power lines. Well-timed elimination and organization of maintenance and repair work to put power lines into operation require high accuracy of fault location. Fault location methods based on the parameters of emergency mode using data of electronic (digital or optical) instrument transformers have been developed in Ivanovo State Power Engineering University (ISPU). The use of electronic transformers makes it possible to reduce the instrumental error of fault location due to accurate measurements of electrical quantities during short circuit, including the measurement of the derivative of the primary current. The aim of the study of fault location methods developed by the ISPU team is to evaluate the errors of these methods with a variation of many factors affecting the calculation of fault location in an automated mode using modern modeling tools. A multifactorial automated research of the fault location methods is carried out using a simulation model of an ultra-high voltage network in the Matlab + Simulink software package. One-sided and two-sided fault location methods based on the parameters of emergency mode developed in ISPU are chosen as the studied methods. In the research methodology presented in the article, the values of the factors affecting the measurement of fault location, including the parameters of the network element models, are changed using a program in the MATLAB language with parallel calculations performed on different processor cores. A technique for automated research of fault location methods has been developed including a model of an ultra-high voltage electrical network in Simulink and a simulation model control program in Matlab. More than 100,000 computational experiments have been carried out for each fault location method. According to the study, the influence of transient resistance is excluded, and the influence of the network frequency is practically absent in the two-sided method. The change in the parameters of power transmission lines and equivalent systems is less affected in comparison with the one-sided method. The Monte Carlo method of fault location algorithms has shown that the errors of one-sided method do not meet the requirements of PJSC «FGC UES» standards in less than 20% of cases, and the errors of the two-sided method under the same modeling conditions do not meet the requirements only in 1% of cases. The developed research methodology makes it possible to evaluate the accuracy of fault location methods when changing the set of factors influencing the measurement in an automated mode. The carried-out research of one-sided and two-sided fault location methods based on emergency mode parameters and data of electronic transformers has showed sufficient accuracy on the model of a 500 kV overhead power transmission line with changes in individual factors affecting the measurement of fault location and when randomly setting a set of parameters of the network model.

Early Warning Analysis of Grid Ferromagnetic Resonance Overvoltage Risk Based on Multi-source Data

In the impartial factor ungrounded system, ferromagnetic resonance overvoltage is a frequent fault that lasts for a lengthy time and is hazardous to the grid. In this paper, the mechanism of grid ferromagnetic resonance overvoltage is first explored in depth. The precept of impartial voltage shift and ferromagnetic resonance brought about through PT saturation is analyzed with the aid of graphical and mathematical analysis. Then, the characteristics of fault current information are extracted by wavelet transform, and indicators such as wavelet fault degree, wavelet singularity and wavelet energy measurement are obtained respectively. D-S evidence theory is used to fuse multi-source information of electrical volume and switching quantity, so as to obtain comprehensive fault results of power grid more accurately. Finally, based on the time series risk assessment, the distribution network time series risk index is calculated, the risk level and risk area of each period are determined, and the early warning results are issued. Finally, an example is given to verify the effectiveness of the proposed method.

Experimental evaluation of conducted disturbances induced during high frequency switching of active components

Introduction. Power electronics devices are among the most widely used equipment in all fields.

The waveforms of the current and voltage across each component during its opening are presented. The results of the simulations are compared and validated with the realized measurements in order to better present the influence of the fast switching of semiconductors on the electrical quantities, which causes electromagnetic disturbances in the interconnected electrical system.

The Use of An Arduino Uno Ultrasonic Sensor in Desalination Equipment's Water Filling Control

A sensor called an ultrasonic sensor works by converting electrical quantities into physical quantities (sound) and vice versa. An Arduino Uno is required to activate the system's ultrasonic sensor. The reservoir's water level is determined using ultrasonic sensors. The purpose of this investigation is to learn how to put together, program, and utilize the HC-SR04 Arduino Uno ultrasonic sensor with the Arduino IDE (Integrated Development Environment) application. Controlling the water in the desalination system is required so that the water entering the reservoir does not waste or overflow and pollute the desalinated water. An ultrasonic sensor is attached to a seawater desalination system using the evaporation method, and the sensor is put on the edge of the evaporation pond in order to conduct experimental testing of the ultrasonic sensor on the device. The desalination tool can operate more efficiently and under control with the help of the HC-SR04 ultrasonic sensor by automatically filling the water in the evaporation pond. The sensor will automatically supply the water shortage when the seawater evaporates. Results of experimental observations made with the HC-SR04 ultrasonic sensor on an evaporation bath with three water filling cycles are available. so that after 7 days, 13% of the volume that was filled in the evaporation basin has evaporated.

Sensor Fusion for Power Line Sensitive Monitoring and Load State Estimation.

This paper deals with a specific approach to fault detection in transformer systems using the extended Kalman filter (EKF). Specific faults are investigated in power lines where a transformer is connected and only the primary electrical quantities, input voltage, and current are measured. Faults can occur in either the primary or secondary winding of the transformer. Two EKFs are proposed for fault detection. The first EKF estimates the voltage, current, and electrical load resistance of the secondary winding using measurements of the primary winding. The model of the transformer used is known as mutual inductance. For a short circuit in the secondary winding, the observer generates a signal indicating a fault. The second EKF is designed for harmonic detection and estimates the amplitude and frequency of the primary winding voltage. This contribution focuses on mathematical methods useful for galvanic decoupled soft sensing and fault detection. Moreover, the contribution emphasizes how EKF observers play a key role in the context of sensor fusion, which is characterized by merging multiple lines of information in an accurate conceptualization of data and their reconciliation with the measurements. Simulations demonstrate the efficiency of the fault detection using EKF observers.

Power capture analysis of a five-unit oscillating water column array integrated into a breakwater in terms of flow field visualization

Oceanic waves possess immense untapped potential as a renewable energy resource, presenting a remarkable opportunity for energy extraction. To unleash the full extent of wave power within a given region and generate substantial quantities of electricity for widespread distribution, it is plausible to envision the deployment of wave farms—expansive arrays comprising wave energy converters. This study investigates the performance of an oscillating water column (OWC) array system integrated into a straight breakwater for wave power extraction. The array consists of five identical rectangular-shaped OWC units with a circular-curve bottom profile, arranged in a linear configuration. Computational Fluid Dynamics simulations are conducted to analyze the power capture of the array system and understand the operational dynamics compared to individual OWC device. Flow field visualization is employed to gain insights into the array effects and the influence of the transverse spacing between the interior units. The array configuration reveals that the OWC units positioned at the lateral sides exhibit the highest performance, while the central chamber achieves the lowest performance. However, none of the units within the array surpass the wave power extraction of an individual OWC device. The array effect introduces interference, significantly influencing the velocity field distribution of the water flow and contributing to disparities in wave power extraction between the individual device and the closely-adjacent array configuration. The study also emphasizes the role of transverse spacing between the interior units in the array. Within a certain range of transverse spacing, increasing the spacing enhances the power capture by mitigating destructive interactions involved in the inflow and outflow processes between adjacent chambers. However, when the transverse spacing becomes sufficiently large, the behavior of each unit within the array resembles that of an individual OWC device, and the constructive interaction effects between units become negligible, thereby weakening wave power extraction.

Energy generation by crystalline silicon photovoltaic network per meter square in Iraq

&lt;span lang="EN-US"&gt;Iraqi people have been without energy for nearly two decades, even though their geographic position provides a high intensity of radiation appropriate for the construction of solar plants capable of producing significant quantities of electricity. Also, the annual sunny hours in Iraq are between 3,600 to 4,300 hours which makes it perfect to use the photovoltaics arrays to generate electricity with very high efficiency compared to many countries, especially in Europe. This paper shows the amount of electric energy generated by the meter square of crystalline silicon in the photovoltaic (PV) array that already installed in 18 states in Iraq for each month of the year. The results of the meter-square of PV array in three tracking positions are presented in this paper. This paper shows that the average electricity generated in North cities (Dohuk, Al-Sulaymaniyah, and Erbil) are less than the southern cities in the winter season (three positions) by about 40-50%. Iraq has a stable PV electrical generation during all the year in all regions except the North cities while the highest cities in electricity generation are (Najaf and Al-Anbar).&lt;/span&gt;

Daily rolling estimation of carbon emission cost of coal-fired units considering long-cycle interactive operation simulation of carbon-electricity market

The high overlap of participants in the carbon emissions trading and electricity markets couples the operations of the two markets. The carbon emission cost (CEC) of coal-fired units becomes part of the power generation cost through market coupling. The accuracy of CEC calculation affects the clearing capacity of coal-fired units in the electric power market. Study of carbon–electricity market interaction and CEC calculations is still in its initial stages. This study analyzes the impact of carbon emissions trading and compliance on the operation of the electric power market and defines the cost transmission mode between the carbon emissions trading and electric power markets. A long-period interactive operation simulation mechanism for the carbon–electricity market is established, and operation and trading models of the carbon emissions trading market and electric power market are established. A daily rolling estimation method for the CEC of coal- fired units is proposed, along with the CEC per unit electric quantity of the coal-fired units. The feasibility and effectiveness of the proposed method are verified through an example simulation, and the factors influencing the CEC are analyzed.

ANALYSE STATISTIQUE DE LIMPACT DES PANNES DU RESEAU ELECTRIQUE SUR LES SOURCES ET LA CHARGE: ETUDE DE CAS DU RESEAU ELECTRIQUE DE LA COMMUNAUTE ELECTRIQUE DU BENIN

Breakdowns in the electricity network contribute to economic losses and upset populations who are increasingly dependent on this source of energy in their daily lives. The Benin Electric Community (CEB) is in charge of the electricity transmission network for Togo and Benin. It is responsible for dispatching the national sources of electrical energy production in the two countries and the import sources to the distribution networks of the two nations. Minimizing breakdowns and blackouts of this network will make it possible to contribute effectively to the economic and technical development of the company on the one hand and the socio-political development of the two countries on the other. This study aims to analyze the impact of breakdowns of the CEB network on the socio-economic level of the two countries on the one hand and on the electrical quantities of the operation of the network (sources or loads) with the aim of proposing a digital failure prediction solution. To achieve this objective, an analysis based on descriptive statistics and statistical linear regression was used. The results showed that more than 55.68% of breakdowns are caused by distribution networks. Earth faults are the most represented among the failures inherent in network control and management systems. There is an impact of blackouts on the social level. The populations of Parakou in Benin are the most affected with cumulative service unavailability of 75 days 19 hours 52 minutes. The economic impacts on the CEB were also recorded. For the correlative study, it appears that there is a weak negative correlation between the number of triggers and the sum of the sources of the CEB. This indicates a possibility of predictive detection of network failures using data from CEB sources. In the rest of this work, a stochastic statistical analysis of the data would be made to determine a mathematical model in order to design the CEB network failure prediction tool.
