    摘要:

    配电系统的最新趋势表明,非线性负载的使用将在未来呈现上升的趋势,因此研究了并联型有源滤波器,用来消除谐波,从而提升电能质量。使用一种无谐波检测方法,从而使补偿精度不再受负载电流检测精度的影响,输出电流波形的控制使用一种优化的准比例谐振控制器完成。在并联型有源滤波器主电路系统结构的基础上,提出了一种电压电流双闭环及电流比例负反馈的准比例谐振优化控制方案。最后,通过MATLAB/Simulink对所提优化控制方案进行仿真,所提出优化控制的可行性通过仿真实验得到充分验证。

    Abstract:

    Recent trend in the power distribution system is showing that the use of nonlinear loads and devices will take a rising profile in days to come. This introduces harmonics in source side currents which improves the power quality. In this paper, the use of a non harmonic detection method, so as to improve the accuracy of the compensation is no longer affected by the load current detection accuracy, control of output current waveforms using an optimized quasi proportional resonant controller. On the bases of shunt active power filter main circuit structure, the optimal control strategy of the quasi proportional resonant voltage current loop control and current ratio of negative feedback. Finally, through MATLAB/Simulink simulation results of the proposed control strategy, the proposed control strategy is feasible through the simulation experiment are fully verified.
