The Functional Design on Fault Recorder of μC/OS-II-Based Intelligent Substation

Abstract:

Regarding the functional requirements for smart substation in fault recorder, this paper introduced μC / OS-II, an embedded real-time multitasking operating system as the functional design. The program works with the embedded operating system, the state machine theory and new methods for embedded development, whilst tasking full use of the advantages of such functions as task scheduling, message queues, etc., aiming to achieve a fault recorder function of intelligent substation. More than taking care of the difficulty of programming, it could improve the program reliability and portability. The program has been applied in an intelligent substation protection in centralized control unit, which has brought back a good fault recorder performance. On this basis, more functions can be integrated, including network log analysis, state estimation, etc., in order to truly meet the application requirements of the smart substations.
