SoE在干熄焦余热发电控制系统中的设计与应用

摘要

In CDQ waste heat power generation unit, in order to find out reasons of failure and shutdown quickly,SOE (sequence of events) system is designed to analyze reasons of failure and shutdown in this paper. The redundant 1756-L63 and redundant 1756-CNBR of Controllogix were used in SoE system. After the application of SoE, the event information is acquired with the resolution of milliseconds, and the current event of failure and shutdown is successfully detected.%为保证及时查明干熄焦余热发电机组发生故障及停机的原因，以ControlLogix系统为基础，CPU采用1756-L63冗余控制站、ControlNet网络采用冗余的1756-CNBR模块与远程I/O站通讯，设计应用了控制系统的事件顺序记录功能。应用SoE后，实现了以毫秒级的分辨率获取事件信息，可成功地检测出引起机组故障停机的原因。
