It proposes a simulation method based on the Partial Element Equivalent Circuit (PEEC) for modeling the fast transient processes associated with the operation of primary equipment in UHV FSC. Initially, a multi-conductor system model for both primary and secondary equipment on the cascade platform is developed. Then, the lumped components\u2032 modeling of primary equipment and secondary equipment is added on the basis of multi-conductor model. Through simulation, the rapid transient overvoltage of primary equipment and the electromagnetic disturbance of the secondary system are analyzed. The simulation results provide insights into the distribution of fast transient overvoltage and the transient electromagnetic disturbance along the bus, from the low-voltage bus to the high-potential platform, under various primary equipment operating conditions. These findings provide a basis for theoretical analysis of the layout of sensor devices on platform and the design of electromagnetic shielding for interference-prone systems on platform.<\/jats:p>","DOI":"10.3390\/s25154662","type":"journal-article","created":{"date-parts":[[2025,7,28]],"date-time":"2025-07-28T09:53:02Z","timestamp":1753696382000},"page":"4662","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Study on the Fast Transient Process of Primary Equipment Operation in UHV Fixed Series Capacitors Based on PEEC Method"],"prefix":"10.3390","volume":"25","author":[{"given":"Baojiang","family":"Tian","sequence":"first","affiliation":[{"name":"State Grid Henan Electric Power Company, Zhengzhou 450052, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kai","family":"Xu","sequence":"additional","affiliation":[{"name":"State Grid Corporation of China, Beijing 100032, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yingying","family":"Wang","sequence":"additional","affiliation":[{"name":"Central China Branch of State Grid Corporation of China, Wuhan 430200, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pei","family":"Guo","sequence":"additional","affiliation":[{"name":"Electric Power Research Institute of State Grid Henan Electric Power Company, Zhengzhou 450052, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chao","family":"Xiao","sequence":"additional","affiliation":[{"name":"Electric Power Research Institute of State Grid Henan Electric Power Company, Zhengzhou 450052, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Han","sequence":"additional","affiliation":[{"name":"Electric Power Research Institute of State Grid Henan Electric Power Company, Zhengzhou 450052, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yiran","family":"Dong","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Power Transmission Equipment Technology, School of Electrical Engineering, Chongqing University, Chongqing 400044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4771-9456","authenticated-orcid":false,"given":"Jingang","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Power Transmission Equipment Technology, School of Electrical Engineering, Chongqing University, Chongqing 400044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"109186","DOI":"10.1016\/j.epsr.2023.109186","article-title":"Research on TRV transient characteristics of EHV controllable series compensation line","volume":"220","author":"He","year":"2023","journal-title":"Electr.
