| 摘 要： | 提出一种负荷采用感应电动机模型时的暂态电压稳定的判断方法.该判据通过比较扰动后感应电动机电磁转矩和机械转矩以及转差的变化情况来判断负荷的稳定性,以系统的最大传输功率与负荷功率需求的关系来确定负荷失稳是否会导致暂态电压失稳.以单机单负荷系统和IEEE39节点系统为例,用MATLAB软件进行仿真分析,仿真结果验证了所提出的方法的准确性.

| Abstract: | A criterion for transient voltage stability of the power system with induction motor is proposed. The criterion determines the stability of the induction motor by analyzing slip change and comparing the values of electromagnetic torque and mechanical torque. Whether transient voltage instability of power system would be introduced by load instability is determined by the relationship between power systems＇ maximum power transmission capacity and load＇s power demand. The correctness of the proposed criterion is verified by the simulation results of a single-generator-single-load system and the IEEE39-bus system. |
