Application of array 1 MW flywheel energy storage system in rail transit

本文根据城市轨道交通的运行特点和车辆参数提出了一种1 MW阵列式飞轮储能系统,用来吸收再利用机车制动时产生的制动电能。通过对比不同类型的再生制动能量回收方式,突出飞轮储能系统应用在城市轨道交通的必要性和先进性。文中通过对某些线路进行数据测试,根据现有单台飞轮储能装置进行阵列式组合,通过产品优化以及安全计算和工程实施预判,组装出容量为1 MW的阵列式飞轮储能系统,并证明了1 MW阵列式飞轮储能系统在城市轨道交通应用的正确性和可实施性。

A 1 MW flywheel energy storage array system is proposed according to the operation characteristics and train parameters of urban rail transit to absorb the braking power generated when the train is braking. By comparing different types of regenerative braking energy recovery methods, the necessity of application of flywheel energy storage system in urban rail transit are analyzed. The 1 MW array flywheel energy storage system is carried out from the array optimization, security calculation and project implement anticipation based on the test data for the rail transit electrical drive line. The feasibility of 1 MW flywheel energy storage array system applied in urban rail transit is verified.
