摘　　要：准确、快速地检测农电系统电流的谐波成分是保证滤波器具备良好工作性能的关键。采用同步旋转park变换的d-q法对并联混合有源滤波器的谐波电流进行了检测,并进行了仿真分析。该方法不仅应用于三相平衡系统的谐波检测,也适合于电网电压有畸变和不对称情况下的检测。经实验和仿真,验证了该方法的准确性和实时性。The key of guaranteeing the work performance of filter is the real and fast time detection of harmonic ingredient of current in Rural Power system. A harmonic current detection method is presented on the base of d-q calculating modes of Synchronous rotation park transformation in shunt hybrid filter,and the result is conducted by simulation analysis . The method not only can detect harmonic current in the system of balance,but also can satisfy harmonic current detection in the condition of distortion. The experiment and simulation results demonstrate the veracity and precise of this method.
