4 Frequently Asked Questions about “High-speed rail power system energy storage device - ID Solar Energy Systems”
What is energy storage system in high-speed railway power system?
Energy storage system is an important part of high-speed railway power system. Energy shift can be realized by energy storage system. Energy storage system can capture the residual energy from the regenerative braking by charging. The demand for power purchase of the system can be reduced by discharging when the traction load is high.
What is high-speed railway power system?
High-speed railway power system consists of traction power system and station power system. High-speed railway locomotives generate electrical energy that is fed back to the grid during regenerative braking, and the grid company adopts the policy of ignoring the reverse transmission, which wastes energy on the railway system.
