【摘要】 有源滤波器是一种消除电力系统谐波污染的重要装置。提出了一种建立在ip iq法的基础上,用混合有源滤波器对任意次谐波电流进行检测的方法。该方法是通过增加预置补偿角,对数字控制器产生的时间延迟做出补偿,实现谐波的实时补偿。理论分析与仿真结果表明该方法具有较好的检测功能,且算法简单,易于实现。更多还原

【Abstract】 Active power filter is an important device to eliminate the pollution of harmonics.A new method for random harmonic current detection of hybrid active power filter based on i_p-i_q principle is presented.This method employs added compensatory angle to compensate controller’s time delay and realize the real time compensation.Theoretical analysis and simulation results show that this method has high performance of detecting the harmonics and is easy to implement.更多还原
