A Abstract 目录 目录 IV IV PAGE PAGE VII improve the reliability of the circuit breaker action. The part of software need complete three sections of the current protection function, the RMS of voltage and current, the harmonic analysis and ZSI, etc. which also need to timely response to the operation instructions, display, communication and events requests record. The DSP processing has heavy workload and high real time requirement, so the use of front and back of modular programming mode operation is difficult to complete the software development. So, the embedded real-time operating system μC/OS-II is transplanted into DSP to carry out software development. Experimental results indicate that the group controller basically achieve expectant purpose. Aew intelligent circuit breaker in the ship on the application of power system provides thought method and design basis in the future.
