SMART Catch system utilizes real-time data feeds from various plants through a PI System. Plant information supplied by the OSIsoft’s PI System serves as a backbone to this system and captures, aggregates, and contextualizes the critical data, transforming it into a reliable source of information. All data utilized by SMART system is coming through a PI Server installed at each power station and fetching data from the DCS. The data from the PI Server is available on the Corporate Data Highway which makes it available enterprise wide. PI ProcessBook along with its PI DataLink tool for MS Excel is being used extensively by SMART system to access current process values, archived data, and to develop many templates covering Start-up/Shutdown events, Plant Overview, Water Chemistry, etc. This presentation describes utilization of a PI System in development of SMART Catch system, a real-time solution, intended to provide early warning of emerging equipment problems with diagnostic guidance from SACS centers being established at Corporate and Regional level in NTPC. The presentation also discusses case studies based on the SMART system observations, showcasing the immense potential of a PI System.
