摘要: 混合型电力滤波器由无源滤波器和有源滤波器通过不同的连接方式构成。根据煤矿电网谐波源特性选择了适用的混合型电力滤波器拓扑方式 ,针对其中的有源滤波器部分设计了基于电压检测的谐波电流获取方法 ,并由此构造了电路模型。经仿真实验分析 ,证实该方案具有优良的谐波抑制特性 ,该设计思路和方法是可行的。Abstract: Hybrid power filter is consist of passive and active filters linked by different methods. In this paper, the configuration of hybrid filter suited to coal mines is selected by Characteritics of harmonic source in mine power network. A kind of method which calculates harmonic current using DSP with harmonic voltage detection is proposed and circuit mode is constituted by the method. Excellent harmonic suppression characteristics of the hybrid filter are shown by the simulation results, and the rationality of the design thought of the hybrid filter and the validity of the conclusions are proved.
