INFI-90是美国Bailay公司在N-90基础上推出的第三代分散型控制系统,也是集计算机技术、控制技术、通信技术和CRT显示技术于一体的新型过程控制装置.由于INFI-90的设备来源主要靠国外进口,许多从事自动控制的人员对它还比较陌生,在分散型控制系统的设计、安装、调试和运行维护方面还都缺乏经验,特别是大型大电机组的自动控制系统,受机组安全运行的限制,一般很难在现场对系统进行有效的试验研究.因此,很有必要建立一套采用INFI-90的控制系统仿真装置.
The INFI-90 is the third-generation decentralized control system introduced by Bailay Company based on N-90 and a new type of process control device integrating computer technology, control technology, communication technology and CRT display technology. Most equipment sources are imported from abroad. Many people engaged in automatic control are still unfamiliar with it. They also lack experience in the design, installation, commissioning and operation and maintenance of decentralized control systems. Especially, the automatic control system for large large electric units, Due to the limitation of safe operation of the unit, it is generally difficult to carry out effective experimental research on the site, so it is necessary to establish a set of control system simulation device using INFI-90.
