中文摘要	利用电能测量方法对500Wh飞轮储能实验系统的充放电效率进行测量,飞轮储能系统充放电循环的升速、降速范围为12000r/min～36000r/min～12000r/min,实验中测得电机及其控制损耗为49%。分析表明,即使将电机效率、控制器效率提高到95%,系统充放电循环效率也难以超过80%。综合考虑飞轮储能系统及辅助系统的能耗,探讨了高效率飞轮储能系统的运行方式和条件,飞轮储能系统应用于航天环境对提高充放电循环效率比较有利。; The efficiency of charging-discharging cycle of the 500Wh flywheel energy storage system was tested through the electric energy measurement method.In the charging model,the flywheel speeds from 12 000 r/min up to 36 000 r/min.The speed decreases from 36 000 r/min down to 12 000 r/min in the discharging model.The test showed that 49% of the energy was wasted by the motor and the motor control system.About ten percent of the energy become the bearing and wind friction loss.It is difficult to make the efficiency of the charging-discharging grow up to 80% even if both the motor and the controller efficiency was increased to 95%.The power consuming of the assistant equipment for the running of flywheel energy storage system was considered in the impro-vement of the efficiency of the flywheel energy storage system.It is concluded that the aerospace conditions are very suitable for the running of the flywheel energy storage system in high efficiency.
