摘要
对电力系统无功及谐波电流有源补偿器中采用的脉宽调制（ＰＷＭ）电流波形控制方法进行了研究，提出一种改进的ＰＷＭ预测控制法。仿真结果表明，该方法较现有的其它各种方法具有更好的补偿效果，且具有更广泛的适用范围。
The methods of pulse Width modulation(PWM)used for current wavecontrol of reactive and harmonic current compensator(RHCC)are studied.A modifiedforecasting PWM control scheme is proposed. Sedation results show that bettercompensating effect can be achieved by use of the proposed scheme than other existingmethods under unbalanced and distorted conditions.
