Synchronous machine parameter identification based on the simulation in PSASP

PSASP (Power System Analysis Software Package) is the software for power system simulation independently developed by China, which can be used for the calculation of power system (transmission, power supply and distribution system). This paper studies the online parameter identification of synchronous machine through the simulation in PSASP. The incremental equation for identifying the fifth-order synchronous machine model was given. An identification program was written based on least squares method. Then the simulation data obtained in PSASP was input the program. The results verified the effectiveness of using PSASP simulation to identify the synchronous machine parameters.
