摘要
建立了光伏阵列、风力发电机和蓄电池模型,基于蓄电池最佳充电电流曲线,提出先恒流后恒压的两阶段充电方式,并利用双闭环PID控制实现了蓄电池的恒压限流充电。通过对该双闭环控制系统仿真研究,结果表明该模型合理有效。
The article established circuit models of photovoltaic array, wind turbine and battery. It applied the twostage battery charging control （constant current-to-constant voltage） which based on the ＂best battery charging current curve＂, and then realized it by double-loop PID controller. The article also simulated the system. The simulation results proved that the model of the system and the double-loop PID control are effective and reasonable.
