Abstract: Aiming at the lack of friendly and convenient visualization tool for parameter identification and verification of excitation system of synchronous generator, based on Matlab/GUI development platform and modeling guide for excitation system of synchronous generator, a visualization tool for parameter identification and verification of excitation system of synchronous generator was designed, the functional requirement and architecture design of the visualization tool was provided, the realization method and feature of the tool including excitation system modeling module was described, parameter identification module, parameter verification module and result output module, and accomplished the test of the tool by making use of the measured generator excitation system data. The test results indicate that the complex operating procedures and calculation processes can be packaged and simplified to the input and adjustment of key parameters through modularization and localization, which can effectively reduce the complexity of the operation. Automatic identification algorithm and regularization of the expert experience can guarantee the accuracy of automatic identification results and reduce the dependence on staff skills and experience. The visualization tool developed can reduce the amount of operation by 40%.
