摘要
讨论了直流牵引变电所在供电系统运行仿真中的建模问题。直流牵引变电所主要由整流变压器和硅整流器构成。在进行直流牵引供电系统的运行仿真时,将其按戴维南电路建模,其等效内电阻和理想电压源由交流电源和整流机组的参数以及负载情况决定。本文给出了12脉波整流机组的计算实例。
It discusses modeling of DC traction substation in simulation of power system. De traction substation are composed of transformer and silicon rectifier circuit. It gives mathematics modeling by Thevenin circuit in simulation of power supple system. Its equivalent resistance and ideal voltage source are decided by AC supply, the parameter of rectifier unit and lord instance. It gives an example of 12-pulse unit.
