摘　　要：为了减少地铁供配电系统中谐波带来的危害, 提高电能的利用率, 有必要对地铁供配电系统中谐波产生的原因进行分析, 并找出特征谐波次数, 从而正确选择滤波器.本文对地铁运行现场的实际电能质量数据进行采集分析, 发现特征谐波次数与整流机组脉波数有关.然后通过数学仿真论证特征谐波次数与整流机组脉波数之间的关系, 从而证明假设是正确的.In order to reduce the harm of harmonics from the power supply and distribution system of the subway and improve the power utilization rate, it is necessary to analyze the cause of harmonics and find out the main frequency of harmonics, so that we can select the filter correctly. The actual operating data of power quality was collected in the subway running site, it was found that the main frequency of harmonics were closely related to the pulse number of rectifier. What＇s more, the relationship between main frequency of harmonics and the pulse number of rectifier was researched by mathematical simulation, which proved that the hypothesis was correct.
