摘要
针对地铁运行站间距短、启动加速和制动减速频繁等特点,尤其是再生制动所产生的巨大能量,可通过飞轮储能装置吸收贮存。基于飞轮储能的再生制动能量回收控制策略,通过飞轮储能充电吸收地铁车辆再生制动所产生的巨大能量,在地铁车辆启动时,经飞轮储能装置放电又回送储存的能量;分析了飞轮储能的充放电控制策略,给出了电流、电压以及速度调节器的参数整定公式,并通过仿真验证了飞轮储能装置能够满足运用所需,有效控制了地铁牵引供电系统中的电压波动。
Due to the operation characteristics of short distance between stations,start acceleration and brake deceleration frequently and the huge energy generated by regenerative braking for the metro vehicles can be absorbed and stored by flywheel energy storage device.Based on the control strategy for recycling regenerative braking energy of the flywheel energy storage,the great energy generated by regenerative braking of metro vehicles was absorbed by slywheel charging the flywheel energy storage device could be used to absorbed regenerative braking energy,and sent it back when vehicles start.The charging and discharging control strategy of flywheel energy storage was analyzed,and the parameter setting formula of the current,voltage and speed regulators were provided.The flywheel energy storage device could meet the requirements of operation was verified by simulation,and effectively control the voltage fluctuation in the metro traction power supply system.
