基于Simulink的电力系统仿真研究

Research of Power System's Simulation Based on Simulink

介绍如何根据一个电力系统的电路模型在Simulink环境下构建系统的仿真模型。对于系统在空载运行时变压器低压侧母线发生三相短路的暂态响应进行仿真研究,通过对理论计算和软件仿真所得到的结果进行比较分析,表明用模型仿真得到的系统运行特性与理论计算一致,Simulink的仿真平台是分析供电系统实时运行的重要工具。

This paper introduces how to build up a Power System＇s model in the Matlab / Simulink environment based on it＇s circuit mechanism.The system processes on idle load when three-phase short circuit fault occurs on the bus.Research results show that the performance obtained from the model is consistent with those obtained from theoretical calculations.Nevertheless,simulation results also show that modeling and simulation by using Matlab/Simulnk play an important role in understanding the theory of power system＇s operation.
