变电站综合自动化在NBR装置供电系统中的应用

Integrated automatization for substation applied to power supply system of NBR plant

变电站综合自动化由继电保护与监控系统组成， Ｉ Ｓ Ａ 变电站微机成套保护装置，增加了多项新功能。在各种过流保护时，使过流动作值减小１２ ．３８ ％ 以上。 Ｂ Ｊ 监控系统由各从控部件及微机保护柜收集保护数据，转发给远方调度所及当地监控机；接收远方发来的控制命令。汉字显示运行及故障结果，操作灵活，分析处理故障及时。

The integrated automatization of substation is composed of relay protection and monitoring system. ISA complete sets of the computerized protection equipment added various kinds of new functions. The over current motion value is reduced more than 12.38% during various over current protections. The protection data are collected from various slave-controlled parts and computerized protection cabinets by BJ monitoring system, then transmit them to a distant dispatcher's office and local monitors. BJ also receives a distant control command. The run and breakdown results are displayed with Chinese character and the operation is flexible. The analyzing and removing breakdowns are in time.
