乌石化炼油厂利用DCS现有的报表功能实现了DCS自控率自动统计，将PID控制模块的手自动模式（仪表位号.MODE）作为一个变量，引入到DCS报表Excel表格中，判断出这个变量在手自动哪种模式上，然后统计出自动模式的控制回路数量即可完成实时查看控制回路投自动情况。实时监控生产装置自控回路状态，记录回路状态的相关信息，自动进行自控率计算，提高了管理人员的工作效率，并通过自动数据采集和标准统一的计算方法，有效保证了数据的客观准确性及考核管理的公平和公正。另外，在DCS报表中引入仪表调节器输出值，这样能直观的显示所有仪表阀位开度，并将30%以下开度工作的控制阀进行统计，以提高阀门预知性维修的准确性。%PetroChina Urumqi Petrochemical refinery by using the DCS function of the realization of the existing report DCS automatic rate automatic statistics, manual and automatic mode PID control module (the instrument tag number.MODE) as a variable, is introduced to the DCS statements in the Excel table, determine the variable in which model, then statistics of the number of control loop automatic mode, you can complete the real-time view of the automation of case control loop. Real time monitoring of production unit automatic control loop state, record relevant information loop state, automatically controlled rate, improve the efficiency of the management staff, and through the calculation method of automatic data collection and unified standards, effectively guarantee the accuracy of data and objective examination management fairness and justice. In addition, the introduction of instruments in the report of DCS regulator output value, so it can display all instrument valve opening, and the 30% following the work of opening the control valve for statistics, in order to improve the accuracy of the predictive repair valve.
