摘　　要：针对同步发电机励磁系统缺乏友好、便捷的可视化参数辨识和校核工具的问题,基于Matlab/GUI开发平台,依据同步发电机励磁系统建模导则设计开发了一种同步发电机励磁系统参数辨识与校核可视化工具,给出了可视化工具的功能需求和架构设计,描述了工具包含的励磁系统模型搭建模块、参数辨识模块、参数校核模块和结果输出模块的实现方法及其功能特点,并利用某发电机励磁系统实测数据对开发的工具进行了测试。测试结果表明:通过模块化和局部化将复杂的程序操作和计算过程封装简化为少量关键参数的输入与调整,可有效降低操作繁杂度,参数自动辨识算法及专家经验规则化,可保障自动辨识结果的精度,降低对人员技能经验的依赖,开发的可视化工具可减少40%的操作量。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%.
