摘　　要：分析了一种采用永磁同步电机驱动的飞轮储能系统充放电过程,发现飞轮储能系统反向制动发电过程中传统PI电流调节器dq轴电流存在较大超调振荡,在弱磁区会导致负id电流的误补偿,指出其在高速飞轮储能系统应用存在局限性,并基于以上分析,提出采用复矢量电流调节器在弱磁区反向制动发电过程可取得理想的dq轴电流动态性能,仿真和实验结果验证了方法的可行性。In this paper, performance of magnet synchronous machine is evaluated during a flywheel energy storage system using a permanent both charging and discharging modes of operations. The id an iq of the permanent magnet synchronous machine have large overshoot and oscillation during the regenerative braking process, and this results in a mistaken id compensation in the flux-weakening region. The limitation of the PI current regulator is discussed and then the complex current regulator is demonstrated improved response compared with the other regulators. Simulation and experimental results verifiy the feasibility of the method.
