摘要
变电站投运时,因经常发生分频谐振现象而误发母线接地信号,或因谐振引起TV过压过励磁,严重时可能烧毁TV。本文通过对实际谐波进行理论分析,总结出防止分频谐振的几项措施,可供实际工程应用。
The papers analyze the phenomenon of harmonic When the substation begin to work,this phenomenon can affect the operation of substation and gives wrong message usually. In view of this, the author present the preventive measures, which can be used in the engineering.
