SYNCHROPHASORS - INITIATIVE IN INDIA JUNE 20125.2 Detection of fault <strong>in</strong> neighbor<strong>in</strong>g gridsThe synchrophasors data provides a signature of the dynamic power system. In an<strong>in</strong>terconnected synchronous system the effect of the perturbation <strong>in</strong> one part can be sensed atother parts with the help of data from synchrophasors.5.2.1 Case Study-14: Three phase fault at 400 kV B<strong>in</strong>a on 22-Feb-2012From figure 57 the voltage profile at 400 kV Dadri (<strong>in</strong> Northern Region) shows dip <strong>in</strong> voltage ofall the three phases for a fault a 3 phase fault at 400/220kV B<strong>in</strong>a substation of MPPTCL(Western region). It can be seen that the fault got cleared <strong>in</strong> 520 milli second i.e. <strong>in</strong> Zone-2 time.Figure 57: Dip <strong>in</strong> 3-phase voltage seen <strong>in</strong> Dadri (NR) dur<strong>in</strong>g fault at 400 kV B<strong>in</strong>a (WR)POSOCO Page 71 of 143
