Abstract
In this paper a new voltage control for shunt active power filters is presented. The proposed system is able to compensate one harmonic current flowing into the electric network without the need for measuring the non linear load current, or supply line current. Only the line voltage is measured. The developed control sets, by means of a genetic algorithm, the suitable values of amplitude and phase of the harmonic compensating current used as reference signal for a carrier modulated PWM voltage source inverter. Simulation tests carried out using Simulink and the Power System Blockset, show the reliability and the effectiveness of the compensation action.
本文提出了一种新的并联型有源电力滤波器电压控制方法。该系统能够补偿流入电网的一次谐波电流，而不需要测量非线性负载电流或供电线路电流。只测量线路电压。利用遗传算法确定谐波补偿电流的合适幅值和相位值，作为载波调制PWM电压源逆变器的参考信号。利用Simulink和Power System Blockset进行了仿真试验，验证了该补偿措施的可靠性和有效性。
