输电系统的紧张运行状态可能会导致电压崩溃，从而导致电力供应中断。因此，有必要对电力系统的电压稳定性进行持续监测，以避免电压崩溃。提出了一种评估线路电压稳定状态和应力状态的指标--线路电压稳定指数(LVSI)。该指标可以用来估计以兆伏安计的电力系统的稳定裕度。该指标已在IEEE 30节点和IEEE 118节点测试系统上进行了不同运行条件下的测试，以评估其有效性。
The stressed operating conditions of transmission systems may lead to voltage collapse with consequent interruption in power supply. Therefore, it is necessary to continuously monitor the voltage stability of power system to avoid voltage collapse. In this paper, a line voltage stability index (LVSI) has been proposed to assess voltage stability state and stress condition of lines. The proposed index may be used to estimate the stability margin of the power system in terms of mega volt amp (MVA). The proposed index has been tested on IEEE 30-bus and IEEE 118-bus test systems under various operating conditions to evaluate its effectiveness.
