Design and Implementation of Online Data Assessment Based on E Format

With the extended development of complication of power system, the accurate reflection of power system operation has become an important factor of power system stability. In order to get more accurate data, this paper proposes a software design philosophy of online data assessment system based on E format, which includes Online/Offline data modeling matching, online/offline parameter estimation and online data adjustment. The research plays an important role on practical power system real-time analysis.
