摘　　要：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。As for the AC filters configuration at Deyang converter station in ± 500 kV Deyang-Baoji EHVDC transmission project,this paper analyzes the filtering performance of AC filter system composed of single-tuned high-pass filters, double-tuned high-pass filters,and the shunt capacitors.By comparing the advantages and disadvantages of the different configuration options,the optimal configuration strategy is formulated for different operating power points. The alternative configuration strategy of applying shunt capacitor to replace the 24th /36th double-tuned filter in case of fault is reasonably verified.As a result,a new filter configuration scheme is proposed for Deyang converter station, greatly valuable for the practical project operation.
