摘要

为防止高压直流输电（HVDC）换流阀高频噪声对电力线载波（PLC）通信的干扰，常规方法是在换流站交、直流侧安装高频噪声滤波器，但噪声滤波器时有故障并造成HVDC系统停运。现代电力系统已逐步采用光纤通信，针对此条件下是否有可能取消直流输电换流站的高频噪声滤波器的问题，对高坡—肇庆直流输电系统的高频噪声进行全面测量分析，得到一些有参考价值的数据。在测量数据的基础上，讨论了取消换流站交、直流PLC噪声滤波器的可行方案。

Abstract

In order to prevent the high frequency noise interference from high voltage direct current（HVDC） converter to power line carrier（PLC） communication， the conventional method is that PLC noise filters are installed both on AC and DC sides of a converter， but sometimes， PLC noise filter faults caused the HVDC outages. Modern power system has phased in optical fiber communication， whether under this condition has the possibility to cancel PLC noise filters at HVDC converter station? For such a purpose， a high frequency noise measurement was carried out on Gaopo - Zhaoqing±500 kV HVDC system， and some useful data was achieved. Based on the analysis of measurements， this paper discusses the feasible scheme to cancel AC/DC PLC filters at HVDC converter station.
