    摘要:

    地铁能量回馈系统可以将地铁刹车的能量回馈到电网中,达到节能和稳定直流电压的目的。而充电回路的设计不仅关系到能馈装置的安全运行而且影响并网后对电网系统的冲击。分析了地铁能馈系统的工作原理,并给出交流充电和直流充电2种设计方案和充电流程,最后通过搭建1.2 MW背靠背的能馈系统试验平台,进行了充电和并网试验。试验结果表明,直流充电方案不仅能满足能馈系统的并网需求而且操作流程简单可靠,是理想的充电方案。

    Abstract:

    Subway energy feedback system can put the subway brake energy back to the power grid,to save energy and stabilize DC voltage.The design of the charging circuit is related to not only the secure operation of the energy feedback device,but also the impact on the power grid when the device is connected to the power grid.After analyzing the working principle of subway energy feedback system,AC charging and DC charging,the two design schemes are given with their charging process.Through building 1.2 MW back-to-back test platform system,the charging experiment and the grid connection experiment have been conducted.The results show that the DC charging scheme is the ideal charging scheme,not only because it meets the cut-in requirements of the subway energy feedback system,but also because its operation process is simple and reliable.
