Instrument Control Rate Evaluation Report
Thread Content
Recently, the maintenance center requested a report on the instrument control rate assessment. Thank you all! ! ! !
:Do we need an evaluation report for this too? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? 、
We used to only keep track of the three rates; it’s the first time we’ve heard of the concept of instrument control rate. It seems we’re really behind the times! How is it counted, and what is the basis?
The Maintenance Center of Shenhua Coal-to-Oil Ordos Branch needs this: L. I don’t know how to write it! ! ! !
I think the control rate is roughly similar to the operation rate; in other words, it refers to how many of your instruments and control devices are in use during normal production, and how well they are functioning So you need to clarify what the leader means regarding the statistics; later on, you can share them with everyone, hehe!
I haven’t been in this field for a long time; it seems that aside from process-related factors, it’s the time since the control system was put into use/total operating time
The control rate is the self-control rate, that is, the proportion of the control loop that is in use! ! ! It is indeed necessary to analyze why those circuits that did not initiate automatically 1. Reasons for process changes ； 2. Design reasons (unreasonable control scheme) ； 3. Instrument hardware issues ； 4. The operators are unwilling ； 5. Others
I happened to come across an English version; I’m not sure if it’s useful: What? It measures the \"automatic level of a plant\", reflecting the original design and maintenance skills as well as management practices, as well as the operational capabilities within that plant. It’s a comprehensive KPI. Why? 1. To improve the efficiency of control loops and enable the operation team to move away from manual control. 2. To use benchmarks to determine where we stand. How? Total number of control loops in automatic mode/Total number of control loops in use * 100%
Instrument control rate = Number of active control loops / (Total number of control loops – Number of loops disabled due to process reasons) * 100%.
Are factors such as improper instrument installation, inadequate selection, and poor maintenance not taken into account?
Hehe, in this case it usually needs to be included in the calculation! If this happens frequently, it will affect the control rate! For some units, the instrument control rate is required to be over 90%!
