对同步发电机突然短路的研究

Research on Short Circuit Situation of Synchronous Generator

本文首先采用d、q、O坐标系统对电网中的同步发电机的短路后的情况进行分析,然后推导出短路后的发电机定子电流计算公式,并通过计算机仿真实验验证该公式的有效性。为提高供电系统的稳定性,合理的选择与使用与发电机相联的其它电器及继电器保护设备进行了有益的探索。

This paper adopts d,q,O coordinate system to analyze a synchronous generator which is in a short circuit power system,then deduces the current formula of generator stators,and verifies the effectiveness of the formula by computer simulation.It undertakes a beneficial exploration for improving the stability of power supply system,a reasonable choice and the use of other electrical appliances or relay protection equipment.
