摘　　要：根据基于新型换流变压器的交直流输电系统中谐波抑制和无功补偿新方案,分析计算了谐波电流在新系统下的分布,在此基础上对新建的直流输电实验平台系统阀侧滤波方案进行设计,详细计算了阀侧主要次特征谐波滤波器的设计参数。最后,对新系统下阀侧谐波方案进行仿真,并与传统滤波方案效果进行了对比,结果说明新系统下阀侧滤波方案可有效地将5、7、11和13次谐波抑制于阀侧,大大地降低流窜至交流网侧的谐波含量。Based on a new scheme of harmonic repression and reactive power compensation used in novel converter transformer＇ s AC/DC transmission system, analyzing and calculating the harmonics distribution, and taking the new building DC transmission test platform for example, designing the filtering scheme in the valve side and calculating mainly characteristic harmonics filters＇ parameter. In the last, simulating the new system with filtering scheme in the valve side and contrasting traditional scheme, the results show the filtering scheme under new system can efficiently repress the harmonics in the valve, greatly decrease the harmonics content flowing into the AC side.
