在电力系统电网的稳定性探索背景中给出了定义与分类这是学习电网稳定之基础内容，对确定保证电网保持稳定的方法进行了罗列和陈述包括静态的和动态的。研究中静态负载和动态负载进行比较并它们在什么条件下能更好的促进电网的稳定性，什么时候会使已经不稳定的系统更加趋于崩溃。利用配电网失稳的几种平时所常见的条件和所遭遇的状况进行了动态稳定性研究并介绍了为了保证配电网尽可能的平衡我们所能选择几种措施以及意义。
利用MATLAB对实例的模拟中的电力系统分析软件包（即PSAT）细致比较各种动态负荷的稳定性、电网的稳定性、功角的稳定几个因素相互影响的方式及特殊性。在对各种常见的模型及常见条件的配合搭建下我们可以分析得出最大的因素导致电网进入失稳阶段和崩溃阶段就是感应电动机。这包括系统的影响因素：选择发电机以及某些装置能够调压调频，分接头调整也很重要，还有选择SVC及负荷特性。

Abstract Recent years due to the rapid development of the growing demand for electricity and the community, voltage stability range of issues received attention. This paper mainly constrained by economic and environmental stability of the distribution network to explore, taking into account the distribution network in peak time is often at its limit state can guarantee its stability issues must be decided knot.
The definition and classification in the stability of the power system distribution network to explore the background of this is to learn the basics of stable distribution network, to determine the distribution network to ensure stable methods are listed and statements, including static and dynamic . Promoting the stability of the distribution network of research of static load and dynamic load they can better compare and under what conditions, what time would have become more unstable system crash. By distribution instability usually common to several conditions and it encountered the dynamic stability of the situation and describes the distribution network as much as possible in order to ensure the balance that we can choose several measures and significance.
The use of MATLAB simulation examples of the power system analysis software package (PSAT) detailed comparative stability of the various dynamic loads with grid stability, steady power angle several factors affect each other way and particularity. In models with a variety of common and common structures under conditions we can draw the biggest factor analysis led to the distribution network into the instability and collapse stage is the stage of the induction motor. This includes influencing factors: the device is capable of selecting the generator and some regulator, also very important to adjust the taps, as well as select the SVC and load characteristics.
