摘　　要：为解决电网系统载荷波动大的问题,研制了200 kW/180 MJ飞轮储能系统实现动力调峰运行。采用有限元法对飞轮轴系进行建模与仿真,计算出飞轮转子临界转速、振型;并对以机械轴承为支撑的飞轮转子进行模态及谐波响应分析;进行多次飞轮升降速全周期检测,记录飞轮运行过程的幅频特性,进行对比分析。飞轮储能系统运行良好,未产生摩擦,振动幅度最大为1.6 mm,小于设计空隙3 mm。A 200 kW/180 MJ flywheel energy storage system is designed to solve the problem of large load fluctuation of the power grid system.The finite element method is used to model and simulate the flywheel shafting,and the critical speed and vibration mode of the flywheel rotor are calculated,and the modal and harmonic responses of the flywheel rotor supported by mechanical bearings are analyzed.The full cycle detection of the flywheel speed rise and fall is carried out,the amplitude-frequency characteristics of the flywheel running process are recorded,and the amplitude-frequency characteristics of the flywheel are compared and analyzed.The flywheel energy storage system is running well without friction.The oscillation amplitude s maximum analysis result is 1.6 mm less than the designed gap of 3 mm.
