牵引变电所的外特性及其在继电保护中的应用

The theory of external performance of traction substation and its appliance in relay protection

根据电路原理和电机学的基本理论,结合电气化铁路的实际状态,构成三相牵引变电所和牵引供电系统的等值电路,得出外特性曲线。同时。

On the basis of the circuit theory,electromechanics and practical state of the electrified railways,we have made up equivalent circuit of threephase traction substations and traction power supply systems and have got external performance curves.At the same time,important practical values of the equivalent calculation circuit and external performance curves have been expounded in the design,motion and relay protection setting for the electrified railways.
