Review on Capacity Optimization of Traction Transformer for High-Speed Railway

In electrified railways, traction load not only fluctuates between peaks and valleys, but also has a situation of low utilization rate average throughout the day short overload. The transformer selects capacity with peak as demand boundary, which will cause to be even lead economic decline power supply system. This article summarizes existing configuration methods for optimization transformer. Then under conditions energy storage new access system, three aspects are described follows. Firstly, device is connected can pull achieve shifting valley filling. Then, possibility integrated system optimize optimal by using such wind light summarized. Finally, this paper discusses current structure it looks forward feasibility cooperating devices
