中文摘要：
基于稳定域边界二次近似，提出了暂态电压稳定裕度指标，并分析了计及感应电动机机电暂态过程的单负荷无穷大系统的暂态电压稳定性。仿真表明：该指标具有准确度高及易于计算机实现等特点，具有较好的工程实用性，并可应用于判断系统暂态电压稳定裕度和估计暂态电压稳定的临界切除时间以及故障排序。
英文摘要：
Based on the quadratic approximation of the stability region boundary, this paper proposes a transient voltage stability margin index, and analyzes the transient voltage stability of a one-machine and one-load system including an electromechanical transient model of induction motor. Simulations show that the proposed index has the advantages of high accuracy, high engineering practicability and facility of computer-implementing, and can be applied to obtain the margin of the transient voltage stability, estimate the critical clearing time of transient voltage stability and rank the severity of the contingencies. Simulations show that, for the system of this paper, the heavier load and larger static portion of mechanical torque in the load are more inclined to lead to transient voltage instability.
