摘要
提出了一种新的ip、iq运算方式,为单相电路有源电力滤波器谐波电流的实时检测提供新的方法。该方法的算法简单且容易实现,可以实时准确地检测出基波电流或各次谐波电流。计算机仿真结果有效地表明该方法能达到预期的效果。
A new ip, iq calculating modes is presented and it offers a new harmonic currents detecting method for active power filter in single-phase circuit. The arithmetic of this method is simple and can be realized easily. This method can precisely detect fundmental current or harmonic current instantaneously. Computer simulation results confirm the validity of the proposed approach.
