扎鲁特——青州±800kV特高压直流换流站传导电磁干扰水平研究
Research of Conductive Electromagnetic Interference in Converter Station of Zhalute-Qingzhou ±800 kV UHVDC Project
摘要
Abstract
The paper conducts the quantitative analysis of the conductive electromagnetic interference of Zhalute-Qingzhou ±800 kV/10 000 MW UHVDC project. Based on the design method of existing projects and the considerations of the features of this project under study, the main parameters of primary devices in converter stations are de-signed, and the broadband equivalent circuit of converter valve, converter transformer, smoothing reactor and AC/DC filter banks are presented. On the basis of these works, the whole broadband equivalent model of the converter station is built, the electromagnetic interference characteristics of the voltage/current of valve tower are analyzed, the attenuation characteristics of converter transformer and smoothing reactor on the conducted electromagnetic interference characteristic are researched respectively, and electromagnetic interference characteristics under different firing angles are compared. This paper provides the necessary reference for the subsequent study of this UHVDC project.关键词
