SYNCHROPHASORS - INITIATIVE IN INDIA JUNE 20125.5 Validation of steady state SCADA and offl<strong>in</strong>e network modelThe synchrophasors data has been used for validation of network model <strong>in</strong> SCADA or offl<strong>in</strong>esimulation studies. Case studies <strong>in</strong> the follow<strong>in</strong>g section illustrate these applications.5.5.1 Case Study-27: Validation of the SCADA network model <strong>in</strong> NRA study was carried out to validate the SCADA network model with the help of synchro-phasordata. Figure 84 shows the phase angles obta<strong>in</strong>ed from SCADA data and synchrophasor data.Rihand and V<strong>in</strong>dhyachal at located <strong>in</strong> close vic<strong>in</strong>ity <strong>in</strong> south eastern part of Uttarpradesh. Theangle between Rihand and Dadri (SCADA) and V<strong>in</strong>dhyachal and Dadri (PMU data) wererecorded and compared. It can be observed that both the data are closely match<strong>in</strong>g with eachother.Figure 84: Comparison of Angular Separation based on SCADA measurement and PMUsPOSOCO Page 92 of 143
