摘要
为了提高继电保护装置的可靠性和稳定性,改善其可移植性和可扩展性,基于优先级可剥夺式调度策略,在TMS320F2812DSP硬件平台上,实现了μC/OS-II实时操作系统的移植。以中低压输电线路继电保护装置为例,提出了该装置的保护方案,通过划分不同的任务实现了保护装置的多种功能。根据网络化继电保护装置的需要,在操作系统里嵌入TCP/IP网络协议栈,实现了网络通信功能。采用μC/OS-II的继电保护装置能够很好地满足电力系统的实时性要求。
To improve reliability and stability of relay protection device, and ameliorate its transplant ability and expansibility, this paper realize μC/OS-Ⅱ real-time operation system transplant on the TMS320F2812 DSP hardware platform, based on deprivable priority scheduling strategy. In case of low and medium voltage transmission line relay protection device, the protection scheme is proposed. Through dividing into several missions a variety of functions of relay protection are accomplished, and in order to meet networking relay protection device＇ s need, through embedding TCP/IP protocol stack into operating system, the function of network communication is implemented. Relay protection device transplanted μC/ OS-Ⅱ is able to meet well the real-time requirements in power system.
