储能有轨电车以其无须架设外部供电网、零尾气排放等优点受到广泛关注,其储能单元由充电速度快、充电效率高的超级电容组成,其快速储能技术在短时大功率应用中有较好的技术经济性,非常适用于有轨电车储能。针对传统有轨电车充电装置存在的诸多问题,提出了一种有轨电车新型供电系统,即通过储能变流器并网控制,采用超级电容储能供电方式。仿真及试验结果表明,该供电方式具有功率因数可控、谐波含量低以及输出电压稳定性好等优点,具有极高的推广应用价值。
The energy storage tramcar has drawn much attention due to its advantages of no need to set up an external power supply network and zero exhaust emission. The energy storage unit is composed of supercapacitors with high charging speed and high charging efficiency. The rapid energy storage technology is applied in short-time high-power applications In the better technical economy, very suitable for tram storage. Aiming at many problems existing in the charging device of traditional tram, a new type of power supply system for tram is proposed, which is controlled by energy storage converter and controlled by supercapacitor. Simulation and test results show that the power supply has the advantages of controllable power factor, low harmonic content and good output voltage stability, which has a very high value for application.
