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 consider-ations 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/DCfilter banks are presented. On the basis of these works

the whole broadband equivalent model of the converter stationis built

the electromagnetic interference characteristics of the voltage/current of valve tower are analyzed

the atten-uation characteristics of converter transformer and smoothing reactor on the conducted electromagnetic interferencecharacteristic are researched respectively

and electromagnetic interference characteristics under different firing an-gles are compared. This paper provides the necessary reference for the subsequent study of this UHVDC project.
