ФЕРРОРЕЗОНАНСНЫЕ ПРОЦЕССЫ В СИСТЕМАХ ЭЛЕКТРОСНАБЖЕНИЯ С РАСПРЕДЕЛЕННОЙ ГЕНЕРАЦИЕЙ

Relevance The article is devoted to the study of the possibility of occurrence of ferroresonant processes in power supply systems with distributed generation. Ferroresonant processes cause overvoltages in electrical installations and lead to their failure. In backbone and distribution networks without distributed generation facilities, the phenomenon of ferroresonance has been studied quite deeply, effective hardware and operational measures have been developed to prevent the occurrence of ferroresonance surges in electrical installations. However, the issue of the occurrence of ferroresonant processes in power supply systems with distributed generation, which is a promising direction in the development of the energy sector, seems to be little studied. Aim of research The main aim of the research is to investigate circuit-mode conditions for the occurrence of ferroresonant processes in power supply systems with distributed generation. Research methods To study the circuit-mode conditions for the occurrence of ferroresonant processes in power supply systems with distributed generation, the main provisions of the theory of electrical complexes and systems, the theory of nonlinear electrical circuits, and the principles of controlling objects of electrical complexes and industrial systems were used. Results The circuit-mode conditions for the occurrence of ferroresonant processes in power supply systems with distributed generation are studied. The power supply system of a HF radio center, containing a power plant with a lower installed power or corresponding to the maximum power consumption of the load, was chosen as the object of study. The features of the scheme-mode conditions for the occurrence of ferroresonant processes under conditions of distributed generation are as follows. Due to the insignificant remoteness of distributed generation facilities and consumers, additional opportunities arise for subharmonic ferroresonant processes. When a generating plant is connected to low-voltage busbars, conditions are created for the occurrence of a ferroresonant process involving low-voltage windings of power transformers. The low dynamic stability of generating installations of distributed generation facilities based on synchronous generators reduces the likelihood and duration of ferroresonant processes in the event of phase wire breaks and short circuits on the power line. Generating plants connected via grid inverters have a limited output current and can be turned off by emergency automatics in the event of an emergency operation of the grid, which, as a rule, precedes the appearance of ferroresonant overvoltages in electrical installations. Thus, in power districts with distributed generation facilities, the circuit-mode conditions for the occurrence of ferroresonant processes, known in the centralized power supply system, undergo changes, and it is also possible to form new ferroresonant oscillatory circuits. Keywords: distributed generation, ferroresonant process, power supply system, oscillatory circuit, generating plant, relay protection and automation devices Acknoledgements: The work was carried out under the state order of the Omsk Scientific Center of the Siberian Branch of the Russian Academy of Sciences (project state registration number 122011200349-3).

Economic analysis of graphene aerogel polyurethane sponge production as adsorbent for oil-water separation

In this study, economic feasibility of graphene aerogel polyurethane sponge (GAPU) production as an adsorbent for oil-water separation was investigated. GAPU has been made from graphite and it was further oxidized by the modified Hummers method to form graphene oxide (GO) or it was reduced to form reduced graphene oxide (rGO). The rGO was blended with polyurethane (PU) sponge and this rGO-PU composite was freeze-dried into an aerogel to change their shapes. This study was aimed to determine the economic parameters based on the scenarios of GAPU production being 547, 6,000, and 12,000 tons per year. The first scenario with a selling price of US$ 9.79/kg showed the net present value (NPV) of US$ 1,241,083.23, break event point (BEP) of 44.21%, internal rate of return (IRR) of 8.62%, and payback period (PBP) of 6.48 years. For the second scenario, the selling price is of US$ 2.62/Kg, NPV is US$ 10,075,984.08, BEP is 33.01%, IRR is 33.37%, and PBP is 2.21 years. The third scenario with an estimated selling price of US$ 2.05/Kg showed an NPV of US$ 17,039,863.70, BEP of 27.10%, IRR of 40.60%, and PBP of 2.19 years. The third scenario with GAPU production of 12,000 tons is the best. Sensitivity analysis showed that the selling price of the product decreases by 10% is more unfavorable to the economic value than the price of raw materials increased by 10%. GAPU gets a cheaper selling price than other methods with provided that the economic value is fullfilled when NPV is positive, BEP is less than 50%, and IRR is higher than 15%, and the removed oil can be reused and potential for sale. Finally, it can be concluded that the production of GAPU is feasible.

Implementation of Break Event Point Analysis and Margin of Safety in Profit Planning

The break event point is a certain amount of production that the company must achieve to reach the break-even point (no profit and / no loss). Margin of safety is the amount of production required so that the company does not suffer losses. The determination of the margin of safety is closely related to the break event point, where the margin of safety is at one level above the break event point in terms of determining the minimum sales required. Both of these are some of the instruments that can be used to plan profits. The purpose of this study was to determine the application of break event point analysis at PT. Beton Jaya Manunggal, knowing the application of margin of safety analysis and to determine profit planning at PT. Jaya Manunggal Concrete. This study uses a non-statistical quantitative approach. The data used in this study is secondary data through PT. Manunggal Jaya Concrete in 2014-2018. The analysis method uses the least square method to plan the net profit of PT. Beton Jaya Manunggal in 2019 with reference to the net sales plan. The result of this research is the break event point of PT. Beton Jaya Manunggal in 2014 – 2018 showed a positive trend with the break event point being above the current year's production during 2015 – 2016. Margin of safety PT. Beton Jaya Manunggal in 2014 – 2018 showed an upward trend with negative margins throughout 2015 – 2016. Profit planning using least squares with reference to net sales planning is quite accurate considering that there is only a difference of 2% above net sales recorded in the 2019 financial statements. Net profit PT. Beton Jaya Manunggal was recorded in 2019 at 1.3 billion Rupiah so that profit planning was not carried out based on the consideration that the recorded profit was less or showed a downward trend when compared to the net profit trend in 2014 – 2018.

A superconductor free of quasiparticles for seconds

Superconducting devices, based on the Cooper pairing of electrons, play an important role in existing and emergent technologies, ranging from radiation detectors to quantum computers. Their performance is limited by spurious quasiparticle excitations formed from broken Cooper pairs. Efforts to achieve ultra-low quasiparticle densities have reached time-averaged numbers of excitations on the order of one in state-of-the-art devices. However, the dynamics of the quasiparticle population as well as the time scales for adding and removing individual excitations remain largely unexplored. Here, we experimentally demonstrate a superconductor completely free of quasiparticles for periods lasting up to seconds. We monitor the quasiparticle number on a mesoscopic superconductor in real time by measuring the charge tunneling to a normal metal contact. Quiet, excitation-free periods are interrupted by random-in-time Cooper pair breaking events, followed by a burst of charge tunneling within a millisecond. Our results demonstrate the possibility of operating devices without quasiparticles with potentially improved performance. In addition, our experiment probes the origins of nonequilibrium quasiparticles in our device; the decay of the Cooper pair breaking rate over several weeks following the initial cooldown rules out processes arising from cosmic or long-lived radioactive sources.

A new spectral parameter to predict dominant wave breaking based on the JONSWAP spectrum

Finding a robust and universal diagnostic parameter that determines the onset of deep-water breaking and its strength has been challenging in wave breaking research. In this paper, a new diagnostic parameter (wave-breaking spectral parameter, WSP) is defined based on the significant steepness of the spectral peak ϵp that was initially proposed by Banner et al. (2000) and Babanin et al. (2001). In addition, the WSP formula contains the spectral peakedness parameter Qp and spectral width ν for taking into account the effect of spectral shape on the value of breaking threshold. To derive the WSP formula and verify the prediction ability of this diagnostic parameter, multiple wave types including nonbreaking waves, critical waves, and single and multiple breaking wave trains were generated in our experiments. The wave trains were generated using a linear focusing theory with components following the JONSWAP distribution. Results show that the threshold value of the new WSP, which distinguishes single and multiple breaking events from non-breaking waves, is found to be 0.042. Furthermore, WSP is used in isolated deep-water spilling breaking packets, and its prediction accuracy is compared with that of the kinematic criterion parameter Bx. The results show that WSP has advantages in predicting the onset of wave breaking, especially for non-sharp wave conditions. Finally, the spatial variation of the total loss rate of the wave energy flux ΔFbrE¯¯ΔFbE¯¯ in deep-water unsteady breaking waves was investigated. It was found that the new WSP has a strong linear correlation with the total loss rate of the wave energy flux. Considering that WSP can be mathematically expressed directly using the spectrum, WSP will be parameterized into the dissipation term of the spectral wind-wave model in our future work. It is expected that the calculation accuracy of the dissipation term will be improved, and the wave model's prediction accuracy of wave parameters will be enhanced because WSP provides a reliable wave-breaking threshold value and has a strong linear relationship with the dissipation rate.

Economic Feasibility Study on The Development of Irrigation Channels

Indonesia is an agricultural country where the livelihood of the majority of the population is farming. Geographically, Indonesia is an archipelagic country that has enormous natural potential, both in the marine and agricultural fields. The agricultural sector is a sector that has an important role in improving the welfare of the entire population of Indonesia. Rice fields in Blang Beurandang Village still rely on irrigation from using rainwater to meet irrigation water needs. To increase rice yields, an irrigation network is needed that can flow water to the rice fields. It is necessary to conduct a feasibility study on the irrigation to be built so that it can be calculated from an economic point of view whether the project is feasible or not. This feasibility study is equipped with an analysis using the first method; Net Present Value (NPV), the second is the Benefit Cost Ratio (BCR) analysis, the third is the Internal Rate of Return (IRR), and the fourth is the Break Event Point (BEP). The results of this study are the value of the investment cost of the construction project or the initial capital of the irrigation canal which is IDR. 2,088,058,500, and the value of the operational and maintenance costs is IDR. 9,578,250 per year. The results obtained that NPV was IDR. 30,614,330, BCR was 1.01%, IRR was 5.88% > 5% and BEP occurred in the 22nd year and the 7th month. Based on the calculation results obtained from these four methods, it shows that the irrigation channel construction project has met the eligibility requirements and the project can be implemented or built. This means that the construction of irrigation networks in the village is feasible.

Location Analysis for Arabic COVID-19 Twitter Data Using Enhanced Dialect Identification Models

The recent surge of social media networks has provided a channel to gather and publish vital medical and health information. The focal role of these networks has become more prominent in periods of crisis, such as the recent pandemic of COVID-19. These social networks have been the leading platform for broadcasting health news updates, precaution instructions, and governmental procedures. They also provide an effective means for gathering public opinion and tracking breaking events and stories. To achieve location-based analysis for social media input, the location information of the users must be captured. Most of the time, this information is either missing or hidden. For some languages, such as Arabic, the users’ location can be predicted from their dialects. The Arabic language has many local dialects for most Arab countries. Natural Language Processing (NLP) techniques have provided several approaches for dialect identification. The recent advanced language models using contextual-based word representations in the continuous domain, such as BERT models, have provided significant improvement for many NLP applications. In this work, we present our efforts to use BERT-based models to improve the dialect identification of Arabic text. We show the results of the developed models to recognize the source of the Arabic country, or the Arabic region, from Twitter data. Our results show 3.4% absolute enhancement in dialect identification accuracy on the regional level over the state-of-the-art result. When we excluded the Modern Standard Arabic (MSA) set, which is formal Arabic language, we achieved 3% absolute gain in accuracy between the three major Arabic dialects over the state-of-the-art level. Finally, we applied the developed models on a recently collected resource for COVID-19 Arabic tweets to recognize the source country from the users’ tweets. We achieved a weighted average accuracy of 97.36%, which proposes a tool to be used by policymakers to support country-level disaster-related activities.

Dam Safety Emergency Action Plan: A Current Practice for Hydropower Dam in Malaysia

There are currently 104 dams constructed in Malaysia. The dams were built for various purposes; 16 of them were built for hydropower. The dam's reservoir often presents significant risks to downstream areas if a massive downfall release occurs. The enormous downfall could be due to a dam break event, overtopping, and emergency operational release. An incident may occur due to massive flows over a spillway with high-speed discharge or unexpected peak discharge. The obvious impact of the incident is direct to the community in the downstream area. Although there is no dam failure recorded case in Malaysia since the 1900s, the possibility of dam failure occurring is still there. Therefore, the dams must have an emergency action plan (EAP) to prepare the likelihood of the emergency occurrences. This paper aims to explore the EAP practices for dam incident over the region and review the EAP practices of a hydropower dam in Malaysia. Implementing EAP in the emergency response system would minimise the public and environment's impact due to dam failures. The benefit of establishing an EAP is to create better communication and effective responses system among agencies during dam emergency occurrences. This paper revolves around the EAP practices by dam owners in mitigating the risk of dam failure occurrences.

Predicting the domain and nature of instabilities in charging and discharging Li batteries

A pattern of sequential group-by-group charging or discharging, of Li batteries with phase-separation thermodynamics, was detected by numerical simulations and justified by several experiments published in literature. The present work is the first to quantitatively predict the main characteristics of the sequential symmetry breaking (SB) events, such as the average Li concentration and the fraction of the Li-poor part at the SB transition times. Using a reduced two-zone (Li-poor and Li-rich) model, that ignores gradients in the liquid phase potential (ϕl), we derive an approximate solution predicting the effect of non-uniformity in initial conditions or in imposedparameter (collectively referred to as 'noise') on the characteristics. We show that gradients in ϕl, although extremely small, operate like noise leading to break-up of the homogeneous solution. A bifurcation map, showing the lowest current boundary that ensures a homogeneous lithiation/ delithiation as a function of noise level, is constructed.

Real-time dynamic changes in intraocular pressure after occlusion break: comparing 2 phacoemulsification systems.

To compare real-time intraocular pressure (IOP) response to occlusion break event in 2 phacoemulsification systems. Iladevi Cataract and IOL Research Center, India. Randomized, experimental study. Rabbits were randomized to:Group I (n = 10 eyes), Centurion Vision system with active fluidics, or, Group II (n = 10 eyes), Centurion with Active Sentry. Within each group, parameter set 1 (IOP 30 mm Hg, aspiration flow rate [AFR] 20 mL/min, and vacuum 600 mm Hg) and parameter set 2 (IOP 50 mm Hg, AFR 25 mL/min, and vacuum 600 mm Hg) were tested. Real-time rate of drop and rise of IOP after occlusion break event (mm Hg per second) and percentage reduction of IOP from maximum during nuclear fragment removal were compared. 10 rabbits (20 eyes) were included. Rate of drop of IOP after occlusion break was not significantly different between groups. Rate of rise of IOP was statistically significantly higher in Group II with both parameter sets (199.09 ± 69.28 vs 94.33 ± 45.66 in parameter set 1, P = .006; and 256 ± 45.05 vs 165.25 ± 51.80 in parameter set 2, P = .005), suggesting faster recovery to baseline IOP after occlusion break. The mean percentage reduction of IOP from maximum was significantly higher in Group I (P = .003). Rise of IOP to baseline after occlusion break event was faster and mean percentage reduction of IOP from maximum during nuclear fragment removal was lower when using the Centurion Vision system with the Active Sentry upgrade compared with the traditional handpiece. The ability to sense IOP at the level of the handpiece with the Active Sentry upgrade allows faster mitigation of surge response.
