摘要
为了吸收城市轨道列车再生制动产生的能量和维持供电网络电压的稳定,提出了一种基于非隔离双向DC-DC变换器的大功率超级电容型储能装置。分析了该储能装置的工作状态,并通过计算北京地铁5号线单列车再生制动反馈到电网的参数确定了该储能装置的主要参数。根据储能装置的数学模型和设计参数进行了储能装置双闭环控制器的分析,最后通过仿真验证了控制器的有效性和合理性。
In order to absorb the energy produced by regenerative braking of urban rail train and keep the voltage stability of power supply network,a high-power super-capacitor energy storage device based on non-isolated bi-directional DC-DC converters is proposed. The article analyzes the work state of energy storage device,as well as,detailedly design of energy storage devices by calculating the parameters feedback to supply network at the Beijing Subway # 5 single train regenerative braking.According to the mathematical model and designed parameters,a dual-loop controller is given.Finally,the simulation shows the effectiveness and rationality of the controller.
