摘要
本文比较了小电网中大型泵用笼型异步电动机各种起动方式的优缺点 ,提出了并联电容起动的方案 ;给出了一套完整的电机起动参数、并联电容值的计算方法 ;通过计算机仿真得出并联电容后电机端电压、无功电流、功率因数等起动性能的改善 ;
This paper discusses the advantage of capacitor-compensation starting method used by large squirrel-cage asynchronous motors in small power net;Offers a set of calculation methods of motor starting parameters and capacitor-compensation value;Then a mathematical model for simulating the motor starting performances compensated by the capacitor is established.In the end,simulation results and practice prove that this method is practicable.
