摘　　要：阻尼型双调谐交流滤波器是高压直流输电系统中最常用的滤波器,其优化设计关系到交流滤波器的性能及定值。从不同位置阻尼电阻的双调谐滤波器的统一阻频特性表达式出发,推导出适用于双调谐滤波器的分流比表达式,进一步分析了阻尼电阻对交流滤波器性能和定值的影响。分析了阻尼电阻与电话谐波波形系数之间的关系式,且推导了阻尼电阻对交流滤波器设备定值和造价的影响公式,为阻尼型双调谐交流滤波器的优化设计提供计算依据。最终总结了优化设计的算法和流程。Damping type double tuned AC filter is the most common filter in HVDC system,and its optimal design is related to the performance and value adjusting of AC filter. The harmonic current split ratio expression of double tuned AC filter is derived based on the impedance-frequency characteristics expression of double tuned AC filter with different damping resistances,and the effect of damping resistance on AC filter＇s performance and value adjusting is further analyzed. The relationship between the damping resistance and THFF is derived,and the impact expression of the damping resistance on AC filter ＇s value adjusting and cost is derived,providing the optimization calculation basis of double tuned AC filter. The algorithm and flowchart of optimization design are summarized.
