| Abstract: | 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. |
