PID 性能评估与整定系统在大型烯烃厂的应用

Application of PID Performance Evaluation and Tuning System in Large-scale Olefin Plants

对PID性能评估与整定系统在某烯烃公司的运用情况进行了介绍。通过对各控制回路的性能评估,一张表就知晓几千个回路的运行情况,对平稳率不好的回路进行自整定,实现了自控率、平稳率、仪表和阀门运行情况的实时统计和分析,显著提高了装置的自控水平和管理效率。

The application of PID performance evaluation and tuning system in an olefin company is introduced.Through the performance evaluation of each control loop,a table can know the operation of thousands of loops,self-tuning loops with poor stability rate,realizing real-time statistics and analysis of automatic control rate,stability rate,instrument and valve operation,significantly improving the level of automatic control and management efficiency of the device.
