摘　　要：提出一种飞轮电池储能系统的控制方法,该方法在电压外环和电流内环的双闭环控制结构基础上加入转速控制环,无需切换外环控制对象,通过控制飞轮转速的改变即可实现飞轮电池的充放电过程。在充电过程中,电网决定直流母线电压,利用转速控制环对飞轮转速进行限制,防止飞轮电池过充电;在放电过程中,则由飞轮电池维持直流母线电压的稳定。分别给出电流环、电压环和转速环控制器参数设计。利用Matlab/Simulink软件建立飞轮电池储能仿真系统并在样机上进行实验验证,仿真和实验结果均已验证所提控制方法的有效性。This paper presents a novel control method for the flywheel battery energy storage（FBES）system. Theproposed method adopts a double closed-loop control structure,which is based on an outer DC bus voltage loop cascadedwith an inner current loop,and has an additional speed control loop. It can realize charge and discharge process of theflywheel battery through regulating the flywheel speed without switching the outer loop control object. During the chargeprocess,the DC bus voltage is completely determined by power system and the speed control loop limits the flywheelspeed to avoid overcharge. Accordingly,the stability of the DC bus voltage is maintained by the flywheel battery duringthe discharge process. Meanwhile the controller parameters for current loop,voltage loop and speed loop are designedrespectively. A FBES system was established with Matlab/Simulink to complete the charge and discharge controlsimulation and the sudden loading simulation during the discharge mode. Correlative experiments on a flywheel batteryprototype are conducted. Simulation and experimental results verify the effectiveness of the proposed method.
