Transient Stability Analysis of Power System Based on Grid Point Meteorological Data
In order to ensure that the power system can maintain stable operation under different meteorological condi-tions,the paper proposes a transient stability analysis method of the power system based on grid point meteorological data.Firstly,the grid point data of the transmission corridor of the line are obtained based on numerical model forecast data.Secondly,the line parameters are calculated based on the heat balance equation and tidal current equation of the trans-mission line and using the meteorological data of the transmission corridor.Finally,the power system transient stability mar-gin is calculated using the equal area rule,and several indicators are defined to evaluate the algorithm.The simulation re-sults show that the meteorological factors have a significant impact on the transient stability of the system,and the devia-tion of the transient stability margins calculated under different weather conditions and conventional conditions is within 10%.
