Two-Phase Short Circuit in the Power Grid Powered by a Transformer with a Y/Δ-11 Winding Connection

The article describes main provisions and relations for calculating short-circuit currents and phase currents in a three-phase traction transformer with a star-triangle-11 connection of windings, which feeds two single-phase loads in AC traction networks with a nominal voltage of 25 kilovolts. These transformers provide power to the enterprises of the agro-industrial complex located along the railway line. (Research purpose) The research purpose is in substantiating theoretical equations for digital intelligent relay protection in two-phase short circuits. (Materials and methods) It was found that since the sum of instantaneous currents in each phase is zero, each phase of the transformer works independently. We found that this significantly simplifies the task of analyzing processes with a two-phase short circuit. In this case, the problem of calculating short-circuit currents in the traction network can be simplified by reducing it to the calculation of an ordinary electric circuit with three unknown currents. (Results and discussion) The article describes equations for calculating short-circuit resistances for one phase of the transformer when connecting the secondary winding as a star or a triangle. The currents in the phases of the transformer winding at short circuit for the star-triangle-11 and star-star-with-ground schemes are compared. It was found that when calculating short-circuit currents, there is no need to convert the secondary winding of the traction transformer from a triangle to a star. (Conclusions) It was found that the results of the research can be used in the transition of relay protection systems from electromagnetic relays to modern high-speed digital devices, which will increase the operational reliability of power supply systems for traction and non-traction power consumers.

Optimal Selection of Time-Current Characteristic of Overcurrent Protection for Induction Motors in Drives of Mining Machines with Prolonged Starting Time

The aim of this study is to analyze the effects of mine power network impedance on the starting time of induction motors, as well as on the operation of overcurrent protection relay. Proper selection of the time-current characteristic of overcurrent protection is crucial for the operation of the drive. A specific feature of mining power grids is their high impedance, which results from long cable lines with relatively small cross-sections. This causes relatively large voltage drops and significantly reduces the starting torque of the motor. Reduced starting torque increases the starting time and intensifies the motor overheating. This study analyzes a series of standardized time-current characteristics used in Invertim company protection devices. A simulation study of startup current and starting time was conducted for an exemplary medium-power motor with a large inertia fan at different values of power supply voltage below the rated value. Parameters of the motor equivalent circuit were calculated on the basis of manufacturer data. A new shape of the time-current characteristic has been proposed that would allow for prolonged starting at significant voltage drop in the mine network, ensuring protection from failed starting. This solution can be implemented in digital protection relays in addition to the standard characteristics.

Digital protection and inheritance of ancient villages in southwest minority areas under the strategy of rural revitalization

The growth in urbanization leads to a decline in traditional agriculture in Asia, and consequently, may result in the loss of cultural heritage. The central task of developers and researchers is to obtain and preserve as much reliable information on the heritage item as possible so that it could be recreated in the future. Digital technologies may not only determine the dimensional features of an object but also collect information about its structure and composition. This work offers a novel method to examine the cultural heritage sites, which combines synchronized laser triangulation and laser induced breakdown spectroscopy (LIBS). The results obtained through the application of this method revealed that LIBS was as accurate in detecting the composition of dyes as the IR spectrometry. The proposed method provides complete information of the historical relics (i.e., color, surface reliefs, and chemical composition). Furthermore, the technology is suitable for examining large complex objects in field conditions. This possibility will be addressed in future works.

A Texture Selection Approach for Cultural Artifact 3D Reconstruction Considering Both Geometry and Radiation Quality

3D reconstruction of culture artifacts has great potential in digital heritage documentation and protection. Choosing the proper images for texture mapping from multi-view images is a major challenge for high precision and high quality 3D reconstruction of culture artifacts. In this study, a texture selection approach, considering both the geometry and radiation quality for 3D reconstruction of cultural artifacts while using multi-view dense matching is proposed. First, a Markov random field (MRF) method is presented to select images from the best angle of view among texture image sets. Then, an image radiation quality evaluation model is proposed in the virtue of a multiscale Tenengrad definition and brightness detection to eliminate fuzzy and overexposed textures. Finally, the selected textures are mapped to the 3D model under the mapping parameters of the multi-view dense matching and a semi-automatic texture mapping is executed on the 3DMax MudBox platform. Experimental results with two typical cultural artifacts data sets (bronze wares and porcelain) show that the proposed method can reduce abnormal exposure or fuzzy images to yield high quality 3D model of cultural artifacts.

Improving security for wind energy systems in smart grid applications using digital protection technique

Wind power generation is the clean energy source by which the pollution in the environment can be reduced to an extent and also it can be installed in and around the cities for electrical supply. The wind energy generated at the level of distributed generation also reduces the impact on the transmission system in terms of loss in the line and improves the efficiency of the power system. The increase in the level of penetration of wind power generation into an island power system network, causing severe threat in the system in terms of protection and security. The decrease in system inertia by means of increasing in Renewable Energy Sources (RES) causes an impact on the stability of the system and further may lead to a blackout of the system. The protection and control of this system are becoming more complicated due to the penetration of RES into the system. So in order to solve these issues, an intelligent control technique is implemented between the robust energy storage system and wind energy system. The Load Frequency Control (LFC) is required to emulate the virtual inertia into the island power system to stabilize the frequency variations and power variations. Furthermore, a digital frequency relay is implemented to protect the system from large power fluctuations for longer duration and a security system is implemented for protecting the whole island system from cyber-attacks. To verify the effectiveness of controller as well as protection system robustness, it is tested for different load disturbances and by increasing the penetration level of wind power, the digital relay has been tested for large frequency variation in the system by using MATLAB/Simulink.

Digital consent and data protection law – Europe and Asia-Pacific experience

ABSTRACTA serious dilemma for regulators of the Internet is to ensure that data providers secure the informed consent of digital consumers before accessing and transmitting their personal data. An economic dilemma for Internet regulators is to recognize the economic costs to data providers of informing data consumers about the nature and consequences of consenting to the use of their personal data, while preventing data users from eroding the privacy of those consumers. In issue, too, is a self-management model in which consent to the use of personal data is managed by data subjects and data users, even if the latter dictate the terms of that usage. A further issue relates to the external regulation that oversee how data is managed. This includes a primary framework with which data users must comply. This article will address these issues in the dynamic and evolving sector of data protection across the global economy. It will argue for greater legal consistency and harmonization in the law governing consent to the use of personal data, in defining the nature of that consent, and in devising a regulatory framework that takes account of the cognitive capacities and behaviour of data consumers.

Digital protection of traditional villages of “Retaining Homesickness”

<p>With the rapid disappearance of traditional villages, the traditional culture contained in them has been in jeopardy, and digital protection has become the international trend and necessary way to protect traditional culture. Under the new situation, “retaining homesickness” has become a realistic demand at the national level. Homesickness originates from the distance of time and space. The satisfaction of homesickness demands not only the protection of culture, but also higher requirements for digital technology. The main obstacles to the digital protection of traditional villages are the lack of mechanism and top-level design, the fragmentation of departments and disciplines, and the emphasis on “form” over “spirit” in digitalization. The key to solve the problem lies in the top-level design from the aspects of system and standard, choosing digital memory content based on landscape gene theory, and designing virtual tourism products that meet the needs of homesickness by taking virtual tourism as the service form.</p>
