Majorityof modes lie in the range of Inter-Area Oscillation. All the modes detected haveinsignificant amplitude and of not much of consequences. During 750 MW flow throughHVDC B’wati link to SR no Intra-Plant mode of oscillation was observed either in NEWGrid (at Bhadrawati and Raipur) or in SR Grid (at Hyderabad, Bengaluru and Salem).POSOCO Page 116 of 143
