Selection And Implementation Of High And Low Voltage Power Supply And Distribution System For New Rail Passenger And Freight Car Factory

This thesis analyzed and confirmed on registration and network system of rated voltage of high voltage power supply and distribution system in new type passenger and freight train car manufacturing plant power supply and distribution system by aiming at the requirement on production process and corporate operation management of the plant.It provided an overview of applications of various algorithms for load calculation when exploring the pros and cons of them.As a solution to the problem of sectionalizing switch configuration in high voltage ring network power supply system,this thesis introduced an optimum algorithm and applied the output from this methodology to guide the design of the high voltage system for a new type passenger and freight train car plant.This algorithm has been proven to be fully capable of simulating the grid operation in reality.In the meanwhile,this thesis has completed calculating short circuit current and shed light on selecting and calibrating high and lower voltage power supply and distribution equipment.It further examined the common issues of supplied power in low voltage power distribution system and addressed them with solutions.
