On the low-voltage side of this equalizer, two adjacent battery cells and corresponding switches and transformer windings form a half-bridge unit, and the cells in this unit can be equalized by means of the magnetizing inductance of the transformer. Further, the secondary sides of these transformers are linked to a high-voltage half-bridge unit, whose output connects the entire battery string to realize the equalization between the low-voltage half-bridge units. The proposed scheme achieves time-division multiplexing of power devices in the equalization process, which effectively reduces the cost and volume of the equalizer, and improves its modularity and practicality. Besides, the two-stage balancing structure and continuously controllable equalization current ensure the equalization speed and equalization efficiency. The operating state and principle, parameter calculation and control strategy of the equalizer are thoroughly analyzed. Finally, the equalization verification results based on four series-connected battery cells fully validate the feasibility and correctness of the proposed two-stage hierarchical battery equalizer.","PeriodicalId":143306,"journal":{"name":"2022 IEEE 3rd China International Youth Conference on Electrical Engineering (CIYCEE)","volume":"360 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113989098","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}

This paper studies the protection system of substation indoor operation area based on lidar. It is through installing lidar in the switch room or relay protection room of substation, using lidar positioning technology to obtain the real-time position of the staff, combined with the work content to generate electronic fence. The system can comprehensively judge whether the staff have the behavior of mistakenly entering the interval, cross-border operation, etc., and make local voice alarm when there are violations. The experimental results show that the real-time positioning accuracy of lidar is within 2cm and the recognition success rate reached 99%. Therefore, the use of an electronic fences, automatic generation of defense areas, and real-time monitoring technology can greatly control the operation process of staff and improve the efficiency and quality of substation operation and inspection.","PeriodicalId":143306,"journal":{"name":"2022 IEEE 3rd China International Youth Conference on Electrical Engineering (CIYCEE)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115510751","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}

A vacuum system, together with DBD chamber, is designed to achieve low pressure environment. Also, a one-dimensional fluid model of the CO2 DBD is established for simulation research. Different energization parameters were used, including voltage magnitude, voltage rising rate, repetition frequency and plateau region duration. The relationships between discharge voltage and current waveforms and energization parameters have been analyzed. Experimental results were compared with simulated ones in order to figure out the mechanism and characteristics of CO2 discharge under Mars atmospheric condition. Results showed that the discharge current magnitude is proportional to the voltage rising rate while it is reversely proportional to repetition frequency. The current magnitude is irrelevant to plateau region duration under Mars atmospheric condition. However, the current magnitude, on the falling edge of voltage, is proportional to the plateau region duration under Earth atmospheric condition. This is due to the difference in the mobility of charge carriers under different conditions.","PeriodicalId":143306,"journal":{"name":"2022 IEEE 3rd China International Youth Conference on Electrical Engineering (CIYCEE)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125204194","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}

Virtual Power Plant (VPP) technology has become an important way to improve the economy and reliability of new power systems. Since distributed photovoltaic and interruptible load included in VPP have strong uncertainties, which make system regulation and operation safety difficult, this paper proposes a bi-level optimization scheduling method based on water-photovoltaic storage complementary to improve the overall operating profit of multi-virtual power plants. First, the water-light-storage complementary method is used to realize the coordination of multiple power sources and improve the energy utilization efficiency. Secondly, the power sharing and market game strategies are introduced among multi VPPs and the multi VPP cooperative sharing dispatch model and VPP market game dispatch model are constructed with the objective of maximizing the economic benefits of VPP by considering system uncertainty. Finally, the feasibility and effectiveness of the proposed optimal dispatching method are verified based on simulation case analysis.","PeriodicalId":143306,"journal":{"name":"2022 IEEE 3rd China International Youth Conference on Electrical Engineering (CIYCEE)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127182107","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}
