| 摘 要： | 为了加强高压换流站交流侧滤波器的谐波抑制以及无功补偿效果，针对高压换流站交流侧滤波装置设计展开研究。针对无源滤波器的结构及原理进行分析，构建了滤波器阻抗稳态计算的目标函数，进而对其参数进行选择。针对直流输电检修状态时谐波特性，设计无源滤波器的配置方案和参数设定，并搭建仿真模型。其仿真结果得到:在交流侧装设品质因数为50的无源滤波器，对母线第3、5、7、9次谐波有显著的抑制效果，谐波总畸变率从加装前的1.80%减小至0.14%。当系统直流双极在全压情况下运行时，加装滤波器后能够有效抑制系统的谐波电压含有率，并能够降低其电压波形崎岖程度，进而变得光滑。研究结果表明，设计的无源滤波器对换流站交流侧产生的谐波能够起到很好的抑制作用。

| Abstract: | In order to enhance the harmonic suppression and reactive power compensation effect of AC side filter in high voltage converter station，the design of AC side filter device in high voltage converter station is studied.The structure and principle of passive filter are analyzed，the objective function of steady state calculation of filter impedance is constructed，and its parameters are selected.According to the harmonic characteristics of DC transmission under maintenance，the configuration scheme and parameter setting of passive filter are designed，and the simulation model is built.The simulation results show that the passive filter with a quality factor of 50 installed on the AC side can significantly suppress the 3rd，5th，7th and 9th harmonics of the bus，and the total harmonic distortion rate is reduced from 1.80% to 0.14%.When the DC bipolar system operates under full voltage，the harmonic voltage content of the system can be effectively suppressed by adding filters，and the voltage waveform roughness can be reduced，so as to become smooth.The results show that the designed passive filter can effectively suppress the harmonics generated by the AC side of the converter station. |
