摘　　要：为了实现再生能馈装置在城市轨道交通供电系统中的优化配置,提出一种适用于多列车运行情况的再生能馈装置容量优化配置方法。利用DCTPS软件和PSCAD软件搭建一套包含能馈装置的地铁系统等值仿真模型,在此基础上以能馈装置综合收益最大为目标,利用遗传算法对容量配置进行求解。算例结果表明,所提方法能够保证牵引变电所直流网压处于安全水平,满足牵引供电和再生制动电能吸收的需求,同时也将吸收更多的再生电能,有利于提高城市轨道交通系统的综合收益。In order to realize the optimal configuration of energy feedback device in urban rail transit,a capacity allocation method of regenerative energy feedback device suitable for multi-train operation is proposed. An equivalent simulation model of subway system with energy feedback device is built with DCTPS and PSCAD software. On this basis,the optimal capacity is calculated by means of genetic algorithm（GA） with the objective of comprehensive benefits of energy feedback devices. The simulation results indicate that the proposed method can ensure the DC voltage security of traction substation,satisfy the needs of traction power supply and regenerative braking power absorption and improve the comprehensive benefits of urban rail transit system.
