| 摘 要： | 在高压直流(HVDC)输电工程建设中,为了抑制高压直流换流站中的换流器在运行时对交直流输电线路出线产生的载波噪声干扰,有必要在线路中加装交直流载频噪声滤波器(PLC滤波器)。文章在分析了换流站噪声频谱和载波干扰限制值的前提下,扼要介绍了PLC滤波器工作原理,并结合贵广直流工程中肇庆换流站建设项目,阐述了实施的PLC滤波器设计内容,为今后直流国产化工程提供技术参考。

| Abstract: | In construction of HVDC power transmission project,a PLC filter need to be installed to restrain the noise interference to AC/DC transmission line coming from the converters in HVDC converter stations.This paper analyses noise frequency spectrum of the converter stations,introduces the working principle of PLC,and discusses the design example of PLC filter based on Zhaoqing converter stations,Guizhou-Guangzhou DC project.It provides a technical reference for the domestic DC project in the future. |
