本文论述了元宝山发电厂600MW 机组锅炉保护计算机控制系统的研制和开发,采用 OMRON 公司的可编程序控制器(PC)CV1000和 C200HS,实现了锅炉系统、火焰联锁及释放系统和空气吹扫系统的计算机控制。设计了故障首次记忆及故障排序等功能,故障分辨率小于5ms。由 SYSMAC LINK 构成最小令牌总线通信网。保证了互为热备用的两套控制系统可靠地工作。
This paper discusses the research and development of computer protection system of 600MW boiler protection in Yuanbaoshan Power Plant. Using OMRON programmable logic controller (PC) CV1000 and C200HS, the boiler system, flame interlock and release system and air purge System of computer control. Designed the first fault memory and fault sequencing and other functions, fault resolution is less than 5ms. By SYSMAC LINK constitute the smallest token bus communication network. To ensure that each other hot standby two sets of control system to work reliably.
