摘　　要：将斩波串级调速方案应用于改造绕线式异步电机的矿井提升机电控系统,不仅克服了有级调速的缺点,而且采用闭环控制,使调速性能大大改善,逆变器的容量大为减小,大大改善电机拖动系统的功率因数。This paper presents the use of chop-wave cascade speed-regulation system to the transformation of mine hoist electric control system of wound asynchronous motor which not only overcomes the disadvantages of step-speed- regulation, but also improves the performance of speed regulation with close-loop control, the capacity of inverter is decreased and the power factor of motor driving system is improved.
