Synchronous Generator Parameter Verification Based on Multiple Measuring Hybrid Dynamic Simulation

For improving effectiveness of affection on dynamic simulation result by synchronous generator parameter,this paper presents one hybrid dynamic simulation method based on combination of multiple measuring signal and simulating model.Accordingly it proposes one verification method for synchronous generator electric parameter.This hybrid simulation method uses custom model function to inject willful measuring into simulation model which overcomes defects of traditional method such as limited types and low precision of inject signals and necessity to modify simulating procedure.By using this method,it can precisely inject terminal voltage amplitude,phase angle,excitation voltage and power angle into generator model and strictly verify electric parameter.Aiming at inconsistency of measuring result and simulation result in large power grid,it proposes synchronous generator parameter error source strategy.Level 4 double area example and one practical power grid actual measuring parameter verification example confirm effectiveness of this method.
