一种广域智能保护主机的硬件结构

The hardware configuration of an intelligent wide-area protection main engine

随着数字化变电站建设、通信技术飞速发展,研发了一种广域智能保护控制系统,并重点阐述了其主机总体系统结构、保护主机多种CPU结构、多种CPU结构内部通信方式比较和基于Gbit交换机的通信方式,分析了接入报文特点,并对广域保护系统220 kV尚志、宾州、亚布力变电站具体硬件进行了配置。应用结果表明,广域智能保护主机硬件结构在传输流量控制、系统可扩展性、传输效率、传输的优先级控制具有优越性,能够完全满足广域保护主机要求。

Abstract：With the rapid development of the construction of digital substation and communication technology, an intelligent wide - area protection control system is developed. In this paper, it expounds the general system configu- ration of the main engine, its CPU configuration, the comparison among these CPU configurations and the commu- nication mode based on Gbit switch. The paper also analyzes the characteristic of access message and deploys the specific hardware of wide -area protection system for Shangzhi, Binzhou, Yahuli 220 kV substation. The applica- tion proves that the hardware configuration of the intelligent wide - area protection main engine is superior in trans- mission flow control, system expandability, transmission efficiency and priority control, and meets all the require- ments for the wide -area protection.
