| 摘 要： | 随着电力系统规模的越来越大和复杂程度的越来越高,传统的人工建模已不能满足电力科研实验的要求,为了适应电力系统的发展,采用了基于MATLAB的仿真方法。在分析供电系统变压器低压侧母线短路电流和冲击电流的基础上,利用MATLAB的电力系统工具箱建立短路仿真模型,运行仿真,得出了故障时电压电流波形,分析了其故障特征,得到理想的仿真结果。因此,在电力系统设计和运行中,可以运用MATLAB对电路进行短路计算和仿真,对供电系统的故障分析、继电保护整定具有指导意义。

| Abstract: | With the increasing scale and the increasingly high complexity of the power system,the tradi tional manual modeling can not meet the requirements of Electric Power Research experimentlin order to adapt to the development of the power system,taking a simulation method based on MATLAB.On the basis of analysing short circuit current and the impact current of power supply system transformer low voltage side bus,using MATLAB power system toolbox to established short circuit simulation model,run the simulation,obtained fault voltage and current waveforms,and analysing its fault characteristics,get the ideal simulation results.Therefore,in the power system design and operation,using MATLAB on Circuit for short circuit calculation and simulation,is guiding significance on the power supply system fault analysis and relay protection setting. |
