Abstract: The configuration of relay protection setting is faced with great difficulty because of the increasing scale and complexity of the power system. In this context, in order to solve the problem of slow response of the previous system, which can not realize the on-demand and on-demand WYSIWYG and the lack of self-adaptability of the change generation of relay setting values, the power network structure and relay setting values are organically combined, a visual relay protection configuration management system based on IEC61970-CIM is designed. Draw lessons from B/s frame design system frame, including data access layer, business logic layer and visual display layer, build hardware system around C8051F040, select suitable physical equipment for the system. Based on IEC61970-CIM standardization technology, information database synchronization technology, expert decision system, instruction simulation and error proofing technology, visual technology design system function module. The results show that the average response delay of the designed system is less than that of the relay setting system and the general relay setting automatic calibration system based on the intelligent optimization algorithm in the application of the designed system, the output power of the relay protection is closer to the theoretical value, and the absolute value of the correlation coefficient is larger.
