| Abstract: | The article introduces the characteristics of in dependent electrical power systems and harmonics and reactive current compensation prindple of active power filter （APF） firstly. Then,according to the characteristics of independent power supply system, the article presents a new harmonic current detection method. Through analysis and comparison with conventional instantaneous reactive power theory and the FFT method,shows that the current detection method has great advantages, as simple, accuracy,easy to achieve, and the method was used in the actual active filter device to get a better application,indicating that the method is effective. |
