摘　　要：阐述基于国家电网智能电网调度技术支持系统(D5000系统)的励磁变过流保护协调配置的自动评估方法。以励磁变过流保护和励磁系统强励为研究对象,通过研究两者之间的协调匹配关系,给出励磁变过流保护协调配置的自动校核方法。该方法可以迅速评估励磁变过流保护定值的合理性,防止励磁变过流保护误动而危及机组运行安全。Introduces the automatic evaluation method of coordinated configuration of excitation transformer overcurrent protection based on State Gird smart grid dispatching technical support system(D5000 system).Taking excitation transformer overcurrent protection and excitation system forced excitation as the research object,the automatic checking method of coordination configuration of excitation transformer overcurrent protection is given by studying the coordination and matching relationship between them,which can quickly evaluate the rationality of fixed value of excitation transformer overcurrent protection,and prevent excitation overcurrent protection misoperation which endangers the safety of unit operation.
