针对±500 kV德阳—宝鸡超高压直流输电工程德阳换流站交流滤波器配置问题,分析了由单调谐高通型滤波器、双调谐高通型滤波器、以及并联电容器构成的交流滤波系统滤波性能,比较了不同配置方案的优劣,确定了不同运行功率点下最优的配置策略,并验证了24/36次双调谐滤波器故障情况下采用并联电容器进行替代的配置方案的合理性。分析的结果为德阳—宝鸡直流德阳换流站的滤波器配置提供了新的方案,为实际工程运行提供了参考。
According to the AC filter configuration of ± 500 kV Deyang-Baoji UHVDC transmission project in Deyang converter station, the filter performance of AC filter system composed of single-tuned high-pass filter, double-tuned high-pass filter and shunt capacitor is analyzed. The advantages and disadvantages of different configuration schemes were compared, the optimal configuration strategy under different operating power points was determined, and the rationality of using alternative capacitors with parallel capacitors under 24/36 double tuned filter failure was verified. The result of the analysis provided a new scheme for the filter configuration of Deyang-Baoji DC Deyang Converter Station, which provided a reference for the actual project operation.
