A Relay Protection Measurement Platform Based on Modularization and Logic Diagram

In order to improve the research and development efficiency of relay protection devices, simplify project processes, and enhance the customization and reusability of functions, this paper proposes a relay protection platform based on logic diagram visualization programming and configuration. It can not only encapsulate typical protection and measurement functions into graphical logic modules, but also draw the logic modules into complete logic diagrams. The relay protection and measurement devices developed based on this platform have better reliability, maintainability, flexibility, and reusability. This platform can support logic module unit testing and parallel development of logic modules and diagrams. This development method can greatly improve research and development efficiency, shorten development cycles, reduce operation and maintenance costs, and enhance engineering flexibility.
