摘　　要：为研究独立电力系统采用飞轮储能系统对大功率脉冲负载的供电性能,本文在分析了飞轮储能系统工作原理基础上,对飞轮储能系统建模与仿真开展了研究。采用了PSCAD/EMTDC软件搭建按照其实际组成搭建了SPWM控制的变流器及触发控制信号仿真模型,利用具有大转动惯量、小摩擦系数和小阻力转矩的负载模拟飞轮转子,建立了飞轮储能系统的全系统模型。通过对建立的模型进行仿真,给出了飞轮储能系统在储能状态、放能状态及两者之间的转换过渡时刻的转速、转矩、电流及母线直流电压响应曲线,深入分析表明,该仿真结果与理论完全一致,证明了飞轮储能负载的仿真模型是正确有效的。研究的相关结论可用于相关电力系统供电稳定性的仿真设计。On the base of the operation principle,the mathematic models and simulation of the flywheel energy storage systems are researched to analyze the supplying performance of the high power impulse load in the independent power systems.Software PSCAD/EMTDC is adopted to establish the simulation models of the converter controlled with PWM and its trigger system according to the real case.The full system models of the flywheel energy storage system are established with the flywheel rotator imitated by high rotate inertia,small friction coefficient and small resisting torque load.By the simulation models established,the speed,torque,current and DC-link voltage characteristic curves in the transient during energy storage and energy release are got.The simulation results are same as the theories,which approve that the established simulation models of the flywheel energy storage systems are correct.Conclusions got in this paper can be used for the power system stability design.
