Based on the Utilization and Impact of New Energy Access on Traction Power Supply

With the continuous strengthening of the operating mileage of electrified railways in China, electrified railways are also being popularized. The increase in the mileage of electrified railways has led to an increase in equipment load, an increase in electricity and energy consumption, and an increasingly serious problem of carbon emissions. Connecting photovoltaic and energy storage devices to the traction power supply system and recovering the regenerative braking energy of the train can effectively save energy and reduce consumption. Secondly, the construction of a green power technology framework based on through-type traction power supply, so that the train traction, renewable energy recovery and renewable power can flow naturally in the through-traction catenary, which can appropriately reduce the investment in remote catenary energy dispatching and equipment capacity.
