| 摘 要： | 直流换流站载频噪声干扰,是由换流站交直流换流运行时换流阀开断的暂态过程引起的.该噪声干扰会沿换流站直流出线和交流出线方向传导,造成对PLC通信系统的干扰.安装交、直流PLC滤波器,就是为了抑制载频噪声以达到规定的限制标准.是否安装PLC滤波器,还应结合500,220 kV系统以及近远期电力系统通信发展规划综合考虑.

| Abstract: | The carder frequency noise interference in the HVDC converter station is caused by the transition of the converter valve switching.The noise propagates along the DC and AC lines,interfering with PLC communication system.In order to suppress the noise below limit,DC and AC PLC filters are installed.However,the decision of equipping PLC filter depends on the 500 kV,200 kV systems and near and long-term planning of power system communication development. |
