近年来现代城市有轨电车发展迅猛,现代新型无网供电模式越来越受到广泛关注。下面简要分析基于车载超级电容方式下的车站充电全线无网的牵引供电方案。车站中压供电网络可分为单环网以及双环网两种。单环网的充电站主接线应为单母线不分段,双环网的充电站主接线应为单母线分段系统。(1)单环网形式电源引入点车站主接线采用单母线分段形式,每段母线引入一回10 kV进线,其他各站均采用单母线不分段形式,全线充电站通过10 kV开关柜串接形成“手拉手”
In recent years, the rapid development of modern city tram, a modern new network-less power supply mode has drawn more and more attention. The following brief analysis based on the vehicle supercapacitor charging stations under the network without charging the entire network program. The station medium voltage power supply network can be divided into single ring network and double ring network two kinds. Single-loop charging station main wiring should be a single bus without segmentation, double-loop charging station main wiring should be a single busbar system. (1) Single-loop network power introduction point The main wiring of the station adopts the single busbar sectionalization mode, each busbar introduces one 10kV incoming line, and the other stations adopt the single busbar and non-sectionalized form. All charging stations pass the 10kV switch Cabinet concatenation form “hand in hand”
