In view of complex interface operations, the low efficient development and less functionality of current relay protection resource configuration system, this paper provides the design scheme which has better interface operations, the parallel development method for hardware and software and more perfect configuration function. The system provides the easily accessible and understandable interface to ensure that users can quickly and correctly configure resource files; the system also provides solutions for the separation configuration of hardware and software, which greatly improves the development efficiency; the system supports hardware configuration, software configuration, protection logic diagram configuration and overall configuration for relay protection devices. Results of practice prove that the system will greatly improve the development efficiency, shorten the development cycle, and reduce human and maintenance cost of human for resource files. At the same time, this system is suitable for all levels of users who want to configure and develop resource files of the power the relay protection device.
