The invention discloses a hybrid energy storage method based on flywheel energy storage and related assemblies, and relates to the field of flywheel energy storage. A flywheel energy storage device and a battery energy storage device jointly form an energy storage system; the stability of the voltage of the direct-current bus is maintained through the battery energy storage device, that is, the voltage of the direct-current bus is maintained between the first charging threshold value and the first discharging threshold value, and it is guaranteed that the flywheel energy storage device has enough energy storage capacity while it is guaranteed that the direct-current bus does not have too large voltage fluctuation and power supply is reliable; when the voltage of the direct-current bus is larger than the second charging threshold value, namely, large regenerative braking energy fluctuation occurs, the flywheel energy storage device with sufficient energy storage capacity can absorb large electric energy generated instantly, and therefore the regenerative braking energy can be recycled to the maximum extent when unnecessary starting of the braking resistor is avoided.

    本发明公开了一种基于飞轮储能的混合储能方法及相关组件,涉及飞轮储能领域,通过飞轮储能装置和电池储能装置共同构成储能系统,当城市轨道列车处于再生制动能量较大的低峰期时,先通过电池储能装置维持直流母线的电压的稳定,即将直流母线的电压维持在第一充电阈值和第一放电阈值之间,在保证直流母线无过大电压波动、供电可靠的同时,也保证了飞轮储能装置有足够的储能量;当直流母线的电压大于第二充电阈值,即出现较大的再生制动能量波动,储能量足够的飞轮储能装置可以吸收瞬间产生的较大的电能,以当避免制动电阻不必要的启动,最大程度回收再生制动能量。
