摘要
针对地铁牵引网电压波动剧烈及机车再生制动能量利用率不高的问题,在地铁牵引供电系统中装设超级电容储能元件,提出一种地铁储能型再生能量回收装置。该装置不仅可实现机车再生制动能量的回收利用,还可通过装置与供电系统间协调控制,达到双向稳压、削峰填谷的目的。首先分析系统主电路结构及工作原理;然后构建系统上层能量管理,下层变换器控制的协调控制策略;最后搭建系统仿真模型,模拟分析多种运行工况,验证该装置及控制策略的正确性和有效性。
In order to solve the problems of violent voltage fluctuation of metro traction grid and low utilization rate of regenerative braking energy of locomotive,a novel type of energy recovery device for Metro energy storage is proposed.The device can not only realize the recycling of locomotive regenerative braking energy,but also achieve the purpose of bidirectional voltage stabilization,peak shaving and valley filling through the coordinated control between the device and power supply system.Firstly,the main circuit structure and working principle of the system are analyzed.Then,the coordination control strategy of the upper energy management and the lower converter control is constructed.Finally,the simulation model of the system is built,and the operation conditions are simulated and analyzed to verify the correctness and effectiveness of the device and control strategy.
