Distributed Photovoltaic Grid Connected Power Generation System for High-Speed Railway

The combination of renewable energy and transportation is becoming more and more common. At present, China’s high-speed rail operation mileage has reached 37900 km, ranking first in the world. HSR+PV can help rail transit achieve carbon peak and carbon neutrality. This article takes the Ningxia section of the high-speed railway from Yinchuan to Xi’an in northwest China as an example. It combines the abundant solar radiation resources in the local area to design a distributed photovoltaic power generation system that reasonably utilizes vacant land construction along the high-speed railway. The installed capacity is 7 MWp, and single crystal silicon double-sided double glass 550 Wp photovoltaic modules are used. Fixed brackets are installed on both sides of the slope and vacant land along the high-speed railway. The operation mode is connected to the grid and connected to the 10 kV distribution room along the high-speed railway power supply system, and the consumption method is spontaneous self-use.
