摘　　要：为了检测用于抑制电力系统的谐波、防止谐波对其造成危害的交直流滤波器的性能,根据各换流站设计规范书所规定的25℃下失谐度不超过1%,对南方电网所辖绝大多数直流滤波器和部分交流滤波器进行了调谐特性普测。通过测试发现被测交直流滤波器出现失谐的概率很低,说明交直流滤波器仍处于较好的运行状态。In order to detect the performance of AC＆DC filters that are used to restrain the harmonic of a power system and prevent it from the harmonic harm, this paper makes a general check out to the most DC filters and parts of the AC filters in China Southern Power Grid （CSG） about their tuning characteristics according to the design specifications of disresonance degree less than 1% in the tempreture of 25℃. It is found that the probability of these filters being in disresonance is very much lower, showing they are in good operation.
