Therefore, the paper proposes a high precision prediction algorithm for electromagnetic environment based on hybrid intelligent optimization. The algorithm combines particle swarm optimization algorithm and artificial colony algorithm to fit variogram, so as to break through the limitations of mathematical statistics optimization or single intelligent optimization algorithm in regional electromagnetic environment prediction. In addition, we modeled the regional electromagnetic environment from time, space, frequency and energy domain.

It has the characteristics of large amplitude, high frequency and fast fluctuation. It is easy to cause safety problems such as electrical insulation breakdown of GIS and related equipment. In this paper, the VFTO generated in the GIS of the 1000kV UHV transmission system is taken as the research object. Aiming at this problem, the two suppression measures including metal oxide surge arrester and parallel brake resistance are analyzed and compared by using ATP-EMTP. The simulation result show that both of these measures can effectively suppress the impact of VFTO on the entire power system.","PeriodicalId":194675,"journal":{"name":"2020 6th Global Electromagnetic Compatibility Conference (GEMCCON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114373487","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}

Therefore, in this paper, the Multi-conductor Transmission Lines (MTL) theory is adopted to establish the mathematical model of the traction network and study the current distribution ratio of each conductor while the protection wire is laid on the ground and overhead. According to the Magnetic Inductive Coupling theory, the longitudinal electromotive force of the signal cable is calculated and analyzed. The calculation results show that the protection wire laid on the ground increases the traction return current in the rail and the ground wire, and correspondingly reduces the return current in the protection wire, which leads to the large longitudinal electromotive force of the signal cable. Therefore, protective measures should be taken.","PeriodicalId":194675,"journal":{"name":"2020 6th Global Electromagnetic Compatibility Conference (GEMCCON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131092340","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}
