摘　　要：针对某一工程实例，分析了晶闸管换流装置的换相高频振荡现象与波形的畸变问题，提出了采用交流滤波器同时抑制振荡与谐波的措施。并设计了相应的滤波器，仿真研究表明所提方案对振荡与谐波起到了有效的抑制作用。The frequency oscillation and the wave distortion caused by the thyristor commutation are analyzed for a substation. A reasonable scheme of suppressing both oscillation and harmonics by using an A. C. filter is put forward,and the selection of the filter parameters is discussed. Finally,a good result for suppressing the oscillation and harmonics is verified by the digital simulation.
