摘要
针对楚雄-穗东UHVDC输电系统穗东站,全面测量分析其换流阀产生的高频传导噪声。结果表明,楚穗UHVDC不设置PLC噪声滤波器是完全可行的,不会对邻近线路的载波信号造成干扰。根据测量结果,对已有HVDC的高频PLC噪声滤波装置提出了处置建议。
PLC noise measurement and analysis were carried out on AC and DC sides at Sui Dong converter station of Chu Xiong - Sui Dong ±800 kV UHVDC transmission system. The results showed that it was entirely feasible for HVDC system without the instal- lation of AC and DC PLC filters, and no interference to parallel lines. There are some proposals for HVDC systems having PLC filters installations.
