摘要
本文基于三相光伏发电与有源滤波器的工作原理,分析了一种能够对两者实现统一控制的系统拓扑结构,并基于该系统拓扑结构提出了一种无差拍控制与PI控制与相结合的复合控制策略。所提到的无差拍控制具有响应快速、精度高等特点,能够解决光伏微网系统负载侧的电流突变问题;而PI控制单元具有适应性好,鲁棒性强,算法简单的特点,能提高系统稳定性。最后,利用Matlab/Simulink仿真验证了该复合控制策略的合理性和可行性。
Works based on the three-phase photovoltaic and active filters, a way to both achieve a unified control system topology, and a non-deadbeat control and PI control based on the system topology and combining the hybrid control strategy. Deadbeat control of the mentioned fast response and high accuracy, able to solve the current of the photovoltaic system on the load side to the problem of mutation; PI control unit has a good adaptability, strong robustness, simple algorithm characteristics, can improve system stability. Finally, the use of Matlab/Simulink simulation to verify the rationality and feasibility of the hybrid control strategy.
