| 摘 要： | 并联有源电力滤波器预测电流跟踪控制方法,根据其电路结构及电流跟踪特点,延展传统滞环跟踪控制思想,以数字化的方式单步预测滞环宽度、单步预测脉冲宽度调制(PWM)信号占空比,实现可控功率开关器件以固定的开关频率工作,优化了三相桥式逆变器,并保证补偿电流在一定的误差范围内跟踪指令电流信号的变化,达到滤除谐波、补偿无功的目的。通过数字仿真实验,表明此方法是可行有效的。

| Abstract: | The predictive current traced control method of shunt active power filter is proposed according to its features of circuit configuration and current traced control, which is developed by the fundamental principles of hysteresis band traced control. Through changing PWM duty cycle digitally with step prediction and step predicting hysteresis bandwidth, switching frequency of inverter is optimized, as well as command current is tracked by compensation current in a certain error range to eliminate the harmonics and compensate the reactive power. Through digital dynamic simulation tests the method is available and effective. |
