摘　　要：基于三相瞬时无功功率理论的ip-iq谐波检测方法利用BF506数字信号处理(digital signal processing,DSP)芯片完成对三相负载电流进行谐波检测。首先对谐波检测的方法进行理论分析,然后介绍了有源电力滤波器以BF506 DSP为核心的控制系统的构成,完成对负载电流的谐波检测和补偿。仿真实验表明,这种谐波检测方法在BF506上具有较好的实时性和准确性,能够满足并联型有源滤波器对谐波检测的要求。ip-iq harmonic detection method based on three-phase instantaneous reactive power theory uses BF506 digital sig- nal processing chip to complete harmonic detection for three-phase load current. This paper firstly theoretically analyzes de- tection method, then introduces constitution of control system of active power filter centering on BF506 DSP which is to perform harmonic detection and compensation for load current. Experimental simulation shows that this detection method is provided with better instantaneity and correction and can meet requirement for harmonic detection by paralleled active pow- er filter.
