The measurement results directly affect the control loop of the DC system and are closely related to the reliability of the DC transmission operation. For example, since the control and protection of DC transmission are based on the measurement value of the secondary side of DC voltage divider, if its characteristics are not considered in the control, the control and protection performance will inevitably decline. In this paper, aiming at the DC voltage divider commonly used in UHVDC transmission projects, combined with the actual parameters, the broadband transfer characteristics of the DC voltage divider is proposed, and the simulation and verification are carried out.

The traditional second harmonic differential protection is difficult to distinguish the inrush current and the fault current under the special angle of the transformer closing angle and the certain value of the remanence, which results in the transformer protection not moving or refusing to operate. This paper proposes an optimized support vector machine (SVM) magnetizing inrush current recognition model based on the particle swarm algorithm (PSO), and combines the current waveform itself to perform feature extraction to realize the identification of transformer magnetizing inrush current and internal faults. The influence of closing angle and remanence on inrush current is studied and the effective feature is extracted to identify the inrush current intelligently.

This paper analyzes the scenario when the thermoelectric generating set of the wind-thermal bundled system are withdrawn from operation, resulting in wind turbines experiencing short-time voltage disturbances with weak reactive power support. The probability distribution model of the electrified traction load is established, and the reactive power regulation range of the doubly fed induction generator is calculated. By identifying the equivalent parameters of the power system, a time-domain simulation model of the wind turbines is constructed, and the critical value of tripping is adjusted accordingly, then the operational risk index of the wind turbines is calculated. The simulation results illustrate that the risk of tripping due to the access of impact load is high when the main reactive power source of the system is withdrawn, and it is urgent to develop corresponding emergency control strategies to reduce the operational risk level of wind turbines.","PeriodicalId":252797,"journal":{"name":"2022 4th Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132671456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To evaluate the vulnerability of RMES, a vulnerability evaluation framework is implemented which includes probability modeling of distribution generations (DGs), power flow calculation and comprehensive evaluation. Then, the vulnerability evaluation indexes system is established based on the topological structure and operational risk. Finally, the grey comprehensive evaluation method is applied to calculate the solution of the evaluation models. An improved IEEE-37 test case is built on the CloudPSS platform to test the method. The test results show that the vulnerability indexes of each scheme can be calculated accurately, and the comprehensive vulnerabilities of different schemes can be ranked by the method.

In order to develop the arc extinguishing chamber of a 550kV 80kA circuit breaker and reproduce the process of breaking the arc fault (arc-ignition-arc extinguishing) of the circuit breaker, this paper is based on the existing mathematical model of the arc breaking process of the circuit breaker. The close fault breaking process of a 550kV 80kA circuit breaker was simulated and calculated, and parameters such as the pressure, temperature and axial velocity of the arc extinguishing chamber during the breaking process were obtained, and the boundary conditions were combined for analysis.

Droop control is usually used to maintain the power balance and voltage stability of photovoltaic power supply point, and the voltage stability is realized by reactive power compensation. In the actual photovoltaic microgrid system, due to the transmission line impedance mismatch, there are errors in reactive power distribution. In order to solve this problem, this paper proposes a virtual impedance to improve the accuracy of reactive power distribution, specifically using dynamic virtual impedance to improve the resistance characteristics of the system and compensate for voltage drop. Aiming at the transient impact caused by the voltage surge caused by load removal in photovoltaic microgrid, the changes of active and reactive power are analyzed, and a reactive current control strategy is proposed to stabilize and consolidate the bus voltage. The above strategies are verified by Matlab/Simulink simulation and experiment to verify that the proposed scheme can effectively improve the control performance of photovoltaic microgrid.","PeriodicalId":252797,"journal":{"name":"2022 4th Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114779134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
