Upgrade Of The DCS System Of No. 7 Unit In Datang Wuan Power Plant

In order to improve the effectiveness of the industrial estate.The more and more plant used and popularized DCS as their controlled system.The DCS system of Datang Wuan power plant plays a decisive role in the process of production and distribution control. But by the passing of time,the DCS appears more and more malfunctious.Especially the No. 7 machine has a lot of problems in the repair period. To improve the reliability of the DCS and to serve the manufacture better,this paper mainly carry out how to improve and optimize the old DCS.At the first,the paper analyses cost performance so improvement and optimization to the DCS. Secondly,in order to decrease capital and continuity of the DCS,the most work of the paper is to improving and optimizing hardware and software of the DCS. Last the configurations are renewed to develop the flow picture is renewed to optimize.The DCS after the improvement and optimization can substitute for the old very well.Further the capability becomes better.The DCS after improvement and optimization runs more reliably and steadly.This will improve productive efficiency.
