| 摘 要： | 基于局部相量量测的在线电压稳定监测是目前电压稳定研究中一个活跃的分支。它可分为基于节点局部量测和基于支路局部量测两大类。后者又可分为基于一元二次方程根的可行解域、基于支路传输功率极限和基于支路复功率摄动为0的3种电压稳定指标和方法。文中首先对基于戴维南等值参数辨识的指标和方法进行了分析和评述,继而对3种基于支路量测的指标和方法分别进行了分析和质疑。通过IEEE39节点测试系统进行了数值分析和比较。结果表明,基于支路当地量测的电压稳定指标和方法不能用于复杂电力系统的电压稳定在线监测。

| Abstract: | On-line voltage stability monitoring based on local phasor measurement is at present a very active branch of voltage stability assessment. It can be divided into local bus measurement based methods and local branch measurement based methods. The latter can be classified into three versions,the voltage stability indices based on the feasible solution region of quadratic equation of received bus voltage,the branch power transfer limit and the zero perturbation of branch complex power. A comprehensive review a... |
