Gen loss (MW)

1 GD-I 05-04-2019

15:03 WBPDCL

Bus-II at Santaldih S/S was under shutdown. At 15:03 hrs total power failure occurred at Santaldih S/S due to flash over at B phase

isolator of ST-III resulting tripping all feeders connected to S/S

40 480

2 GI-II 11-04-2019

13:39 ISTS

+/-500 KV Talcher Kolar HVDC Pole 1 got blocked due to Emergency switch off signal

receipt from Kolar end resulting reduction of power flow from 2000 MW to 1000 MW. Pole 2 was operated in metallic return mode after

the incident.

3 GD-I 12-04-2019

23:55 ISTS

At 23:55 Hrs, R-Y phase to phase fault occurred on 400 kV Teesta 3-Kishanganj circuit resulting in its tripping. Subsequently 400 kV

Rangpo-Kishanganj ckt tripped on backup over current protection leading to Isolation of Sikkim Hydro complex (1908 MW) with Gangtok Load (17 MW) and the island collapsed due to large load generation

imbalance causing total blackout of 400/220/132 kV Rangpo, 400 kV Teesta V, 400

kV Teesta 3, 400/132 kV Dikchu, 220 kV Jorethang, 220 kV Tashiding, 132 kV

Chujachen and 132 kV Gangtok substations.

23:30 ISTS

At 23:32 Hrs, 400 kV Rangpo-Kishangunj circuit tripped from Kishangunj end on directional E/F. With this fault, Dikchu

400/132 kV ICT tripped on Backup Overcurrent protection causing tripping of both its units. In addition, during this fault, Jorethang Unit 2 also tripped on generator

protection. The SPS associated with this circuit did not operate at Rangpo End. As the line

loading on 400 kV Teesta3-Kishanganj circuit was 1538 MW, the SPS for Line overloading at

Teesta 3 end operated tripping its unit 1. However, this did not reduce the loading on

the line below the set limit of 2000 Amps. The low voltage persisted at Teesta 3 generating plant and after 5 minutes, the Teesta 3 Unit

2,3,4 and 6 tripped .

10:16 JUSNL

220 kV Ranchi – Hatia D/C was out of service. At 10:16 hrs 220 kV Biharshariff-Tenughat S/C tripped on R-N resulting into islanding of Hatia load with 2 running units of Tenughat and one

unit of CPP Inland power. Island could not survive due to generation load unbalance

leading to the load loss of around 150 MW at Hatia/ Namkum/Lohardangha /Kamdara area in Jharkhand system and loss of two running units of Tenughat and 1 running unit of CPP

Inland. 315 MVA ICT-I & II of Biharshariff tripped sensing the fault of 220 kV

Biharshariff-Tenughat S/C.

02:15 ISTS

At 2:15hrs, 765 KV Bus I at Angul tripped on Bus bar protection due to B ph bursting of CT associated with Tie bay of 765 KV Angul-Jharsuguda IV. At the same time,1500 MVA 765/400 KV ICT IV also tripped on back up O/C protection.
