摘要
介绍了电力系统的暂态稳定、MATLAB环境下Simulink动态仿真工具、电力系统工具箱的功能和特点及仿真数学模型。运用MATLAB电力系统仿真模块集SimPowerSystems构建了三机系统的Simulink模型,通过对电力系统故障仿真分析,表明了该模型能较准确直观地考察暂态过程中电力系统的动态特性,说明了Matlab在电力系统仿真中的强大功能。
The basic characteristics of power system transient stability, the function and feature, and mathematical model of power system blockset and Simulink based on MATLAB are introduced in the paper. MATLAB SimPowerSystems are used to build up Simulink models of a three-machine system. Powerful functions of Matlab in the simulation of power system are shown by the simulation of power system failure. The result shows that the dynamic behavior of power system during transient processes can be observed quite accurately and directly.
