摘　　要：对电力系统稳定性的基本概念进行了阐述,电力系统几乎每时每刻都会遭受到来自于小扰动的威胁,可能会导致电力系统在运行时的各项参数发生很大的变化,从而整个系统运行失稳。因此研究电力系统在遭受小扰动情况下的静态稳定性具有一定的理论和工程实际意义。通过Simulink对构建的单机无穷大系统中的小扰动进行建模和测试仿真,分别对影响静态稳定性的三个条件:自动励磁、系统稳定器、改变电压增益后系统的稳定性进行实验分析,对结果进行验证对比,发现励磁电压增益的作用没有前两者明显。This paper expounds the basic concept of power system stability,the power system will suffer from the threat of small disturbances almost every moment,which may lead to great changes in the parameters of the power system during operation,so that the entire system is unstable. Therefore,the study of the static stability of power systems in the case of small disturbances has certain theoretical and engineering practical significance. Through the Simulink,the small perturbations in the constructed stand-alone infinity system are modeled and tested,and the three conditions that affect the static stability are simulated and analyzed automatic excitation,system stabilizer and system stability after changing the voltage gain,and the results are verified and compared,found that the effect of the excitation voltage gain was not as obvious as the former.
