摘要

介绍了一种为对称和非对称非线性用户提供无功补偿的电力电子无功发电机。控制系统提供补偿系统的惯性操作。通过负载电流的逐步变化，在几个交流电压周期内，VAr发电机将有功功率的某些值传递给线路。结果表明，该电力电子系统可以作为有源滤波器，有效地降低电流谐波。

Compensation of the reactive power drawn from the line by nonlinear consumers

A power electronic VAr generator that provides reactive power compensation for symmetrical and nonsymmetrical nonlinear consumers is described. The control system provides inertial operation of the compensating system. By a stepwise change of the load current, some value of an active power is delivered by the VAr generator to the line during a few AC voltage periods. It is shown that this power electronic system can be used as an active filter for unwanted current harmonics reduction.<>
