摘　　要：针对农村电网中的谐波污染日趋严重的问题,分析了一种并联电感型混合有源滤波器的工作原理,并利用广义积分控制方法来实现电网电流的无差跟踪。利用PSCAD/EMTDC软件进行仿真,结果表明,该算法在并联电感型混合有源滤波器中的应用效果与传统PI控制器相比,能获得较好的滤波效果,为农村电网的谐波治理提供了很好的理论基础。The problem of harmonic pollution becomes more and more serious in rural power grid.To solve the problem,the working principle of the parallel inductor type hybrid active power filter is analyzed,and a generalized integrator control method is applied to track current signals without static error.Simulation experiments are done with the software PSCAD/EMTDC,and the results show that the new algorithm has better steady accuracy and filtering performance in application of parallel inductor type hybrid power filter.Good theoretical basis is provided to correct harmonic in rural power grid.
