摘要

笔者根据糯扎渡±800 kV直流工程招标文件对于PLC干扰水平限制值的要求

提出了交流侧加装2个带调谐装置的1.5 mH电抗器和1个不带调谐装置的100 nF电容器而在直流侧极母线和中性母线上不安装PLC滤波器的噪声滤波器配置方案

并进行了PLC滤波器性能与定值的计算。该研究对于特高压和超高压直流工程交/直流PLC滤波器的设计具有一定的借鉴意义。

Abstract

According to the limit value of PLC interference level in the tender invitation documents of Nuozhadu ±800 kV DC transmission project

noise filter configuration schemes are proposed

in which two reactors of 1.5 mH with tuner and a capacitor of 100 nF without tuner are equipped at AC side

and no PLC filter is needed on pole bus and neutral bus at DC side. The performance and rating of PLC filter are calculated. This study may provide a reference for the design of PLC filter in UHV and EHV DC transmission project.
