High-speed railway traction power supply system design
Abstract:The world has entered a new period of the construction of high-speed electrified railway. Especially in Europe has broken through the borders, to the road network of international development. High-speed electrified railway has become one of the main symbol of national socio-economic level of development and modernization of railways. High-speed railway in the world has had 40 years of history, but China is still in its infancy. Safety rail transport is eternal theme, safe and reliable operation of traction power supply system is to ensure the safe operation of trains on the premise, guaranteed to train safety reliable power supply at the same time, the traction power supply system protection and monitoring aspects also play an extremely important role.
In this thesis, it described constituent elements of high-speed railway traction power supply system and runprinciple from the external power supply, power supply, electric traction, traction substation, traction power supply system protection and control, as well as comprehensive monitoring system and other aspects detailed .And then it designed and analyzed the high-speed railway traction power supply system, to eliminate traction substation power supply equipment hidden, narrow the scope of failure to reduce interference on the transport, restore normal train running order, the purpose of the design.
