乙醇装置粉碎传动设备联锁控制算法研究及应用

Research and Application of Interlock Control Algorithm for Grinding Transmission Equipment of Ethanol Plant

在乙醇装置中,因输送工段传动设备冗长繁杂,物料在整个传动设备中传输,一旦其中某一传动设备出现故障,由于传统联锁控制可能存在联锁响应时间长和响应不及时的缺陷,存在造成堵料等事故的可能性.为解决此问题,结合动态规划思想,将整体的联锁系统问题分解成单个设备的控制方案,改进联锁控制算法来降低设备联锁的时间.利用霍尼韦尔PKS系统对上述两种算法进行了仿真,仿真结果验证了改进算法优于传统算法.

In an ethanol plant,because the transmission equipment in the conveying section is long and complicated,the material is transmitted in the entire transmission equipment,and once one of the transmission equipment fails,because the traditional interlock control may have the defects of long interlock response time and untimely response,there is the possibility of causing clogging and other Accidents.In order to solve this problem,this paper decomposed the whole interlocking system problem into a single device control scheme,and improved the interlocking control algorithm to reduce the time of device interlocking.Both algorithms were simulated with Honeyville PKS system,and the simulation results showed that the improved algorithm was better than the traditional one.
