摘要
容量水力发电机组发生三相短路的时候,短路电流很大,对发电系统的运行危害极大。计算无限大容量供电系统发生三相短路的短路电流较为详细的分析了其中的物理量。通过解微分方程法对无穷大容量电源供电系统发生三相短路进行了简单的分析,解出来其中的物理量,并运用MATLAB对算例进行仿真,验证了分析结果。
When three phase short circuit is happened in capacity hydraulic generator,the short circuit current is very big and has great harm to the power system operation.This paper calculated the short circuit current of three phase short circuit and analyzed the physical quantities.The differential equation method is used to analyze the three phase short circuit of power supply system with infinite capacity and calculate the physical quantities,and the MATLAB is used to the simulation and the analysis results is verified.
