摘要
采用三相不对称半桥SRM功率变换器与PWM变流器构成飞轮储能系统能量转换系统电力电子接口,具有电路简单,易于控制等优点.针对开关磁阻电机飞轮储能系统非线性强、多变量耦合等特点,采用模糊PI控制策略以提高系统的鲁棒性与稳态精度.在能量存储阶段,采用恒转矩与恒功率结合的控制策略,加快储能速度;在能量释放阶段,采用电压闭环控制策略,实现系统的频率、功率和电压控制.仿真结果验证了所提出的飞轮储能/能量释放控制策略的正确性和有效性.
Energy conversion system of flywheel energy storage system with power electronics interface composed by three phase asymmetric bridge converter and PWM converter,has such advantages as simple circuit structure and easy to control.Since flywheel energy storage system with SRM is strongly nonlinear and multivariable coupled,a fuzzy-PI controller is proposed to improve the robustness and steady state accuracy of the system.In the energy storage stage,constant torque control and constant power control are combined to accelerate the speed of energy storage.In the energy release stage,the voltage closed loop control strategy is used to achieve good control for frequency,power and voltage of the system.Simulation results demonstrate the correctness and effectiveness of the proposed energy storage/release control strategy.
