SYNCHROPHASORS - INITIATIVE IN INDIA JUNE 2012Figure 16: Architecture of pilot project in Northern RegionThe synchronized phasor measurement processing system operates as a programmable dataconcentrator with network access to provide a combination of functions including, but not limitedto, simultaneous collection of data from serial- and Ethernet connected phasor measurementunits, correlation and concentration of collected data based on UTC time stamp, andsimultaneous transmission of time-aligned IEEE C37.118-2005 synchrophasor messages for asmany as seven clients.The Human Machine Interface (HMI) workstation application has been developed using proficyreal time information portal SCADA software development environment. The developmentenvironment supports creation of graphic objects that represent the status and conditions,display of analogue values, input field for analogue values. The HMI updates the screen once 2second. It keeps a detailed alarm history of all the alarms, errors and fail-overs.POSOCO Page 36 of 143
SYNCHROPHASORS - INITIATIVE IN INDIA JUNE 20123.1.2 Displays in Operator ConsoleTwo sets of displays are available; one set of displays with data from Historian and second setof displays with real time data from PDC. Few customized displays have been prepared for theoperators. Displays are presently of two types- dial display and trend display.Synchrowave console SEL-5078 is the application-level software package used for viewing datafrom server.Figure 17: Trend display of current phasor magnitudeFigure 18: Trend display of voltage phasor magnitudePOSOCO Page 37 of 143
