A Method of Data Integration Check Based on Online Operation Data of Large-Scale Power System

An important part of power grid voltage stability online intelligent warning system was to research into the current Energy Management System real-time power grid operation parameters and power networks offline data splicing integration, form a set of online dynamic simulation trend data, and implement preventive voltage stability calculation. A splicing model of power grid online data integration and practice was established, and a grid online data splicing method was proposed, which had been verified by actual data. The method of practical data online and offline networks data integration can significantly improve the accuracy of the simulation data.
