摘　　要：μC/OS-II是一种源码公开的实时操作系统内核,具有易移植、可靠、稳定等特点,作者研制了基于μC/OS-II实时操作系统的嵌入式发电机微机继电保护装置,论述了将实时操作系统引入微机继电保护的必要性和应用价值。完成了μC/OS-II在高性能浮点DSP芯片TMS320VC33上的移植工作,将μC/OS-II与TMS320VC33相结合,进而依据保护原理提出了该装置的保护方案。该保护装置的多种功能通过划分不同的任务来完成。实践表明,采用μC/OS-II的嵌入式发电机微机继电保护装置具有可靠、灵活、易于维护等优点。μC/OS-Ⅱ is the kernel of a source-code publicized real-time operating system and is portable, reliable and stable. A μC/OS-Ⅱ based embedded protection device for generator is presented and the necessity and application value of leading real-time operating system into microcomputer based relaying protection is illuminated. On the basis of expiating μC /OS-Ⅱ to digital signal processing （DSP） chip TMS320VC33, the μC /OS-Ⅱ is integrated with high performance floating point DSP chip, then according to the protection principle the protective scheme of the presented protection device, whose multi-functions are implemented by dividing different tasks, is proposed. Test results of the presented protection device show that the embedded generator protection device using μC /OS-Ⅱ is reliable, flexible and easy to maintain.
