摘要
电力系统的电压不稳定现象正受到越来越多的关注。由于一个电力系统的负荷特性对其电压稳定至关重要，因此本文对典型的动态负荷作了全面的研究与仿真，比较了恒功率负荷和感应电动机负荷，研究了感应电动机负荷点的动态和暂态特性，对在稳定性分析中是使用感应电动机的高阶模型还是低阶模型作了对比，同时对感应电动机和恒电流负荷不同组成的动态特性也作了探讨。
The unstable voltage phenomena of power systems are suffe ring increasing concerns nowadays. Since the load characteristics of a power sys tem is most important to its voltage stability, hence this paper carries out a c omprehensive research and simulation for the typical dynamic load. The constant power load and load of induction motors are compared, the dynamic and transient characteristics of node loads for induction motors are studied; in the stability analysis , for the model of induction motor, higher order and lower are compare d; meanwhile, the dynamic characteristics of different combinations of constant current and induction motor loads are explored too.\=
