The National Electric Power Regulatory Authority (NEPRA) has unfurled a 34-page request report about a countrywide power breakdown on January 23, 2023, considering six substances fundamentally liable for the blackout. The authority held the Public Transmission and Despatch Organization (NTDC), Public Power Control Center (NPCC), GENCO-III, Guddu Nuclear energy Plant, and Port Qasim Electric Power Organization (PQEPC) liable for the breakdown.
NEPRA likewise accounted K-Electric (KE) as answerable for the inability to stay in island mode because of the stumbling of Canister Qasim Power station — III.
The report said the breeze age decrease lifted at 07:30hrs., and thus around 500 megawatts age infused in the framework, which caused over-burdening of transmission lines as well as low voltage under consistent state conditions considering long AC hallway of around 1100KM, from Thar in South to Haveli Bahadur Shah in North with the deficient age, as the Guddu 747 Plant was under constrained closure. It diminished the transmission line limit considering Flood Impedance Level (SIL).
Thus, aside from rising pattern in framework recurrence because of expansion in wind age, the motions on the framework likewise began. Simultaneously the age in the Northern locale was decreased by closure of one unit and sloping down the age of one more unit of Ghazi Brotha at around 07:32:22.187hrs. That activity irritated the circumstance as the framework was at that point frail and under pressure because of high AC stream and low voltage/less VAR pay in the center, as per the report.
The postpone in the rebuilding of the NTDC framework was chiefly because of bombed endeavors of dark beginning offices at WAPDA hydel stations and KAPCO. Different variables remembered a deferral for synchronization of different power plants and the non-accessibility of the SCADA (administrative control and information procurement) framework in NPCC. The KE framework was additionally postponed because of rehashed bombed endeavors on dark beginning.
The report referenced that nine endeavors were started from Tarbela to empower the framework with various blends of transmission lines and different region loads, yet all endeavors fizzled and the island couldn’t grow and couldn’t synchronize with Mangla.
The endeavors were additionally produced using the Warsak and Mangla hydropower plants, however no achievement was accomplished. The back start offices at all power plants were seen as profoundly problematic with the exception of the dark beginning capacity of the UCH-I power complex. The dark beginning office at the UCH-1 power plant was profited to empower the framework.
The absence of SCADA and far off tasks fundamentally affects the reclamation cycle of the power framework. SCADA is a fundamental device that permits the framework administrator to screen all framework boundaries which helps the framework administrator in speeding up the activity. Similarly significant is the grouping of occasions, particularly connected with hardware, of the total organization, which by and by are not accessible, and can be recorded at NPCC just through SCADA, as per the report.
Prior, a 18-page request report of the four-part advisory group headed by State Clergyman Musadik Masood Malik had previously been submitted to PM Shehbaz Sharif. Nonetheless, the controller’s report organized 15 arrangements of occasions that occurred during the event of power outages and 18 medicinal measures to deflect future power outages.
NEPRA had comprised 6 part request panel involving Imran Kazi, senior guide, M&E, NEPRA convener, Nadir Ali Khoso, market master part, Ghulam Abbas Memon, market master part, Syed Safeer Hussain, market master part, Manu Smash market master co-pick part, and Syed Aqib Ali Shah, agent chief, M&E, NEPRA secretary.
