The Development & Application Of Urban Railroad Power Supply System Simulation

The computer simulation also called the computer emulation, which is the technique that by the high speed big storage digital computer and relation technique, to turn the complicated real system's running procedure or status into digital emulation. Along with the technical development in computer and high speed, big storage's computer is more popular, at the same time, the simulation technique also get quikly development in engineering design realm and get get good economical performance, and become a kind of trend gradually.The calculation of the urban railway power supply system, all adopt the rate method in ago, only from the macroscopic aspect to designing project. And if use the railway train run diagram cuts method, it would separate the railway by the substation to several dependent power supply segment, the computing only involve 3 substation. In reality, under the normal condition, at the two sides power supply circumstance, by the substation bus line, it is making the whole line to connect segment eache other to trun as a whole entity, the train takes the current from the whole line, the railway train run diagram cuts methodcan not consider this point, also have shortage.This text introduce us, The simulation technique and advanced SQL Server database techniques are synthesized to apply in urban railway power supply system, Imitate the whole line traction net to a complete dynamic electric network, and apply the new the DC traction power supply RS model, making it even approached with train real running and can optimize the design, the engineering profit is obviously.In the first chapter, studying the structure and running performance include the DC traction power supply and AC power supply system.In the second chapter, introduce power flow calculate principle and method in the AC power supply system, then introduce and analysis the power flow calculating method of the urban railroad power supply net.In the third chapter, analysizing the simulation calculating method of the power supply system of urban railway.In the fourth chapter, analysizing the structure and realization method of the simulation software.
