摘要
文章利用MATLAB中的电力系统仿真模块SimPowerSystems工具箱搭建了电力系统中非常具有代表性的单机无穷大系统Simulink仿真模型。该系统模型在发生最为严重的三相短路故障的情况下,对其暂态稳定性进行分析。通过对仿真结果的研究分析,其结果表明该模型能较为准确地、直观地描述电力系统的暂态特性,并说明了系统故障切除时间及故障类型对系统稳定性具有重要影响。
MATLAB SimPowerSystems are used to build up Simulink models of the Single-machine Infinite-bus Power System,which is classical in power systems.The transient stability of power system is studied under the most terrible situation-Three-phase fault in the power systems.The result of simulation shows that the model can describe the transient stability of power system accurately and directly.The fault cleaning time has important significance to the transient stability of power system.
