广东茂名500kV变电站220kV微机母线保护装置的研究

Research on the numberical busbar protection for the 220kV busbar in Maoming 500kV substation guangdong province

介绍了自适应式母线保护装置系统结构及功能,该装置采用多微机、分层式结构,管理机采用高性能的工业控制计算机系统,提供了基于Window95/98/NT全汉化的管理功能和人机交互界面。保护机采用基于intel80386EX、16-bitA/D的STD工业控制计算机系统。采用支持OSI的七层协议的LONWORKS网络,实现管理机与保护机的通信。文中还介绍了母线保护、失灵保护的配置。

The structure and function of the adaptive numberical busbar protection is presents. The multi-CPU, hierarchical structure and high reliability industrial computers are used in the system. The STD industrial computer system based on Intel 80386EX CPU, 16_bit A/D is used in the protection system. Communication among the protection systems and management system is the LONWORKS network supporting OSI seven protocols. Busbar protection, circuit break failure protection are also presented in this paper.
