Static Voltage Stability Emergency Regulation Method Based on Wide Area Multi Source Data
In this paper,an online static voltage stability emergency regulation method based on wide area multi source data is proposed.In order to improve the real-time warning and control,the real-time voltage stability margin is got from the distance between the PMU measuring voltage of key nodes weighted by participation factor and critical voltage value,and the critical voltage value and participation factor of key nodes are calculated by PV curve and QV modal analysis.When the voltage stability margin does not meet the requirements,the control measures is obtained from the pre-decision results in which the control measures to improve different levels of stability margin are given by matching the difference of current margin and target margin with the margin levels.,The effectiveness and practicality of the method have been verified by the cases of actual power grid.
