摘要

对异步电动机进行就地无功补偿是一种投资小、见效快的有效方法。本文就补偿容量的选择进行了讨论

并利用Matlab/Simulink对异步电动机的就地无功补偿进行了仿真。通过仿真验证了异步电动机无功就地补偿在不同工况下不出现过补偿与自激励过电压的条件下

能取得较好的补偿效果。并分析了电压变化时对补偿的影响以及对电容投切时的浪涌电流的限制问题。

Abstract

Local reactive power compensation to asynchronous motor is an effective way with less investment and quick result. In this paper

the selection of compensation capacity is discussed and the local reactive power compensation of asynchronous motor is simulated by the use of Matlab/Simulink. It is verified by the simulation that better compensation result can be obtained under the condition of no occurrence of over compensation and self-excitation overvoltage of the local reactive power compensation of asynchronous motor under different conditions. And the influence to compensation in the case of voltage variation and limit of surge current in case of capacitor switching are analyzed.
