摘要
为适应不同电压等级的城市轨道交通供电系统,提出了一种新型模块化储能系统设计方案;以超级电容储能技术为基础,结合半桥型Buck/Boost双向DC/DC变换器,采用恒流反馈和飞渡电容均压控制策略,实现高效稳定的储能模块设计;最后利用MATLAB/Simulink建立了模块化储能系统的仿真平台,验证了储能模块设计的可行性以及控制策略的合理性。
For adapting to different voltage levels in urban rail transit power supply system, a new energy storage modular design is proposed in this paper. The schema based on super capacitor energy storage technology with the half-bridge Buck/Boost bi-directional DC/DC converter, adopts the control methods of current feedback and adjusts the fit capacitor voltage balance to realize the design of stable and efficient. A simulation platform of energy storage system module is built by using MATLAB / Simulink, the experimental results verify the rationality of the energy storage module design and the feasibility of control strategy.
