摘要
基于广义瞬时无功功率理论,借助dq变换分析了三相有源滤波器DSP控制器中谐波检测模块中低通滤波器设计的特定要求。利用MATLAB软件建立了谐波检测的仿真模型,通过分析比较不同类型、阶数、截止频率低通滤波器对谐波检测效果的影响,确定了谐波检测模块中的各项参数指标。
The detecting of harmonic and reactive current is very important in Power system. Based on generalized theory f the instantaneous reactive power in the three phase systems, this paper analyses the special requirements of LPF (Low Pass Filter) in detecting module of APF (Active Power Filter) DSP (Digital Signal Controller) through using dq vector transform. The influence of different type,order and cut frequency to detecting module are analyzed, the results from SIMULINK show that Butterworth 40 Hz is the best suitable LPF for this DSP controller.
