According to the different power supply equipment, the main function of power supply system is to provide power for locomotive running, while the main function of distribution system is to provide power for some equipment (interval equipment) along the railway. These two power supply modes exist independently and do not interfere with each other. At the same time, when supplying power to the interval equipment, most of the equipment is powered by independent power supply, including the main power distribution and standby power distribution, which are switched through the electrical control circuit. However, in the traditional distribution mode, the overall stability of the power grid is required to be high. If the electric energy of the power grid often fluctuates, it will cause the distribution failure of the equipment in the interval, resulting in the effectiveness of the equipment. Therefore, it is necessary to improve the stability of the interval distribution system and select a more reliable distribution mode. Photovoltaic power generation is a way of railway power supply, whether it is feasible to be applied in railway interval distribution system needs continuous research. Based on this, this paper takes photovoltaic power generation technology in the application of railway interval distribution system as the entry point, and discusses the way of its application, hoping to bring certain reference significance to the application of interval distribution system.展开更多
