| 摘 要： | 随着电力电子装置的普遍应用,其非线性特征而引起的电网电压和电流畸变越来越引起人们的重视,有源电力滤波器(APF)是一种较好的谐波滤除装置,但存在直流侧电压不稳的问题。分析了影响APF直流侧电压稳定的几个因素,推导了电压源型有源电力滤波器的数学模型,结合遗传算法辅助优化计算了该系统中APF的PI调节系数,MATLAB/simulink仿真验证了该方法的可行性,为遗传算法在PI整定方面的研究提供了借鉴。

| Abstract: | With widespread application of power electronic devices, distortion of grid voltage and current caused by its nonlinear characteristics is drawn increasing attention. Active power filter （APF） is an effective harmonic filtering device, but presences DC voltage instability problems. This paper points out the influence of its DC voltage stability on several factors and derives voltage sourcing APF mathematical model. The APF system＇s PI coefficients is optimized using genetic algorithm. The feasibility of the method is verified by MATLAB/Simulink simulation. This paper provides a reference for the application of genetic algorithm in PI tuning. |
