Research and Engineering Practice of Series Reactor Selection in Shunt Capacitor

通过实例对并联电容器的谐振的计算方法、串联电抗器选取与电容器谐振等问题进行了分析,并指出电容器的串抗率选取还应对所有可能出现的运行工部进行全面的谐振点分析计算。

Harmonics resonate the inherent characteristics of shunt capacitor. Series reactor is the most effective method for adjusting the resonant point unable to be eliminated,which could adjust the resonant point away from the integer harmonics. Howev-er,resonance cannot be completely avoided simply by applying series reactor design principle,which was analyzed through the engi-neering examples. Finally,all the conditions of resonant point were analyzed for series reactor selection of capacitor in this paper,and the practical engineering problems of resonant point calculation were further discussed.
