The invention discloses a dynamic configuration technology of a power grid local county office relay protection management system function module. The technology consists of a database module, a configuration management module, an exclusive service module, a system management module and a business operation module. The application of the dynamic configuration technology can improve system establishment efficiency and the expandability of an application function and specifically shows in the following way: the system service functions and interfaces do not need to be developed and can be directly generated through system configuration, a flow can be graphically configured, generated and revised, warning information can be configured, generated and revised, and a report can be configured, generated and revised. Five elements of system business functions are dynamically configured to practically realize a purpose that the system functions are changed along with demands. The implementation of newly increasing or changing business functions, interfaces, flows and warning information in a later stage becomes convenient so as to improve the extensibility of the system to a higher level.
