摘要
在轨道交通能源互联网发展背景下,首先通过分析轨道交通负荷分布特性,阐述光伏应用于交/直流牵引供电系统的发展潜力与意义;其次,针对交流牵引供电系统依据不同的供电制式,从异相(两相)供电制、贯通式同相供电制、机车车载3个角度出发,对国内外研究现状进行综述;针对直流牵引供电系统,通过融合制动能量回收技术,从光伏+能耗型、光伏+能馈型、光伏+储能型、多能互补型4种接入类型展开综述;最后,通过归纳、总结既有研究存在的不足,多方位探讨光伏接入后对电能质量、网压稳定性、负荷预测、系统可靠性、系统保护、利益博弈等特性的影响机理,在此基础上,提出进一步亟待开展的研究重点与建议,以期对推进轨道交通能源互联网的建设,拓宽光伏去补贴的商用化市场研究提供参考。
In the background of development of rail transit energy internet, the potential and significance of photovoltaic(PV) application in AC/DC traction power supply system was firstly pointed out based on the distribution characteristics of traffic loads. Then, according to different power supply modes, the globe research status of AC traction power supply system was summarized, which include different phase(two phase) mode, co-phase mode, directly application in locomotives. And the status of DC traction power supply system was also summarized by integrating different braking energy recovery technologies, which include PV + energy consumption system, PV + energy feeder system, PV + energy storage system. Finally, the impact mechanism between PV and traction power supply system was analyzed from power quality, network voltage stability, load forecasting, system reliability, system protection, economical efficiency, etc. On this basis, further research focuses and suggestions were put forward to provide reference for promoting the construction of rail transit energy internet and broadening the commercial market research of PV de-subsidy.
