    摘 要:飞轮储能对环境的要求和影响非常低,充放电深度和健康状态预测相对简单,且方便实现模块化应用。基于背靠背双 PWM 变频器和永磁同步电机的数学模型,在 MATLAB/Simulink 中搭建了飞轮储能系统单机并网仿真模型,通过分析复杂工况下的仿真结果,发现了系统抗扰动能力差、直流母线电压波动较大的问题,经理论分析,提出了一种背靠背变频器的优化双回路前馈协调控制策略,该方法在传统网侧变换器电流内环控制结构中附加了电容电流控制环,同时引用负载电流估算值和电网电压作为前馈项,通过仿真分析,验证了该控制策略的有效性,能够实现两侧变换器的一体化协调控制,整体提高了飞轮储能系统的自抗扰能力和动态性能。

    Abstract: The flywheel energy storage has little need for the circumstance, and it has a low impact on the environment. In addition, the charging depth of the flywheel energy storage is simple, and the prediction of the health condition is basic.This paper constructed a single-machine grid-connected simulation model of the flywheel energy storage system in MATLAB/Simulink based on the mathematical model of a back-to-back dual PWM inverter and permanent magnet synchronous motor. By analyzing the simulation results under complex working conditions, this research found that the system has a low ability of anti-disturbance and severe problems with DC bus voltage fluctuations.This paper proposed an optimized dual-loop feedforward coordinated control strategy for back-to-back inverters by theoretical analysis. This method added a capacitor current control loop to the structure of the inner current control of the traditional grid-side converter. Moreover,it used the estimated value of the load current and the grid voltage as feedforward terms. It verifies the effectiveness of the control strategy through simulation analysis. In addition, this research proves it could realize the integrated control of the converters on both sides. All in all,it improves the self-disturbance immunity and dynamic performance of the whole flywheel energy storage system.
    Key words: back-to-back inverter; flywheel energy storage system; vector control; feedforward control; load disturbance; pulse-width modulation
