摘　　要：随着各种新技术的应用,电压稳定问题日益突出,根据现实情况提出一种新型电压稳定的计算方法.首先给出了小干扰电压稳定极限的数学模型,从而提出新型电压稳定的判据,通过常规潮流计算与病态潮流计算的方法,对过渡运行方式进行分析,最后通过模态分析的方法确定了系统初始稳态点和稳定极限点的电压功率灵敏度及其参与因子,从而更有效地确定系统的关键节点和区域.最终通过PSASP的实验,验证了该方法的有效性和可行性.With the new technology, voltage stability problems have become increasingly prominent, the paper proposes a new reality based on voltage stability calculation. First, it gives the voltage stability limit mathematical model of small disturbance which proposed a new voltage stability criterion, by conventional power flow calculation and pathological flow calculation methods, analysis of the transition operation mode, and finally through the modal analysis method to determine the system between the initial steady-state point and the point of voltage stability limit sensitivity of their participation in the power factor, so as to more effectively identify critical nodes and regional systems. Final adopt PSASP to test the validity and feasibility.
