摘　　要：文章首先介绍了独立电源系统的特点，并阐述了独立电源系统有源滤波器谐波和无功电流的补偿原理。而后，根据独立电源系统的特点，提出了一种新型的谐波电流检测方法，通过与传统的瞬时无功功率理论和快速傅里叶变换提取谐波方法相比，该方法计算简单、准确度好、实现方便，具有较大的优越性，并在实际的有源滤波器装置中得到了较好的应用，表明该方法是正确和有效的。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.
