The role of the Offline/online data mapping table based on online operation data of large-scale power system

摘要

An important part of the Xinyang power grid voltage stability online intelligent warning system was to research into the current system of EMS real-time power grid operation parameters and power networks offline data splicing integration, forming a set of online PSASP (Power System Analysis Software Package) trend data, implementing preventive voltage stability calculation. By splicing model of Xinyang grid online data integration and practice, summed up the grid online data splicing method and the model, this article mainly introduced the offline and online data mapping change reason, function is established. It had been verified by actual data achieved by the method can significantly improve the accuracy of the data. It was a kind of practical data online and offline networks data integration method.
