摘要
开平市在20世纪70年代所建的小水电站低压机组很大一部分是采用电抗移相相复励磁,这种励磁装置具有线路简单、可靠性高、维护工作量小、无功调节范围宽和自励恒压特性较好等优点。但当使用不正确时,会出现发电机不能发出额定无功的毛病,针对该装置几种常见的发不足无功情况加以分析。
A great part of the low-pressure sets in midget water power stations built in 1970's in kaiping city are adopting reactance phase shift phase compounded self excitation,the advantage of the excitation equipments are straightforward circuitry、high dependability、little maintenance work、broad range idle adjustment and excellent self-excitation constant voltage characteristic. The generators can not give off rating idle when in improper usage. The article is aimed at analyze on some kinds of common defects of idle deficiency.
