【摘要】 运用MATLAB/Simulink中的电力系统仿真模块(Sim Power Systems)搭建单机无穷大系统,重点研究自动重合闸装置的作用效果。从理论上分析了自动重合闸装置的作用原理,通过单机无穷大系统的仿真,研究在电力系统发生短路故障情况下,对故障线路进行切除、自动重合闸等操作时对电力系统暂态稳定性的影响,并通过间接法测量得到的功角来确定系统能否保持暂态稳定。更多还原

【Abstract】 The power system simulation module( Sim Power Systems) in the MATLAB/Simulink is used to build single machine infinite bus system,for the detailed study of the effects of single-phase reclosing. Then theoretically analyzes the function principle of single-phase reclosing. And based on the simulation,the transient stability of the power system under short circuit fault,considering cutting fault line and reclosing,is analyzed. At the meantime,the power system is transient-stable or not is judged by the power-angle,which is measured using indirect method.更多还原
