摘　　要：对串联电抗器的作用、抑制谐波的原理以及串联电抗器电抗率选择时应注意的问题进行了简单的介绍,通过对某供电公司进行现场实测,发现变电站的谐波电流以及谐波电压已有不同程度的超出了电能质量国标限值,针对这一现象,对电容器串联电抗率的选择问题进行了重点分析,同时指出,选择合理的电抗率仅仅考虑避开谐波放大区以及对谐波电压放大率的验算是不够的,还应做更为细致的相关工作。The function of series reactor,the principles of harmonic restraint and the issues in series reactor selection have been briefly introduced.Spot measurement in a certain power supply company shows the harmonic current and voltage in substation have exceeded the limitations of national standards in different levels.The selection of capacitor series reactance ratio has been focused on. It is pointed out that avoiding harmonic amplification zone and checking voltage amplification ratio are not enough,further work should be carried out in detail.
