This document provides an overview of an individual's experience restoring the power system from complete collapse as the Deputy Manager of the Power Distribution Company (PDC) in Multan, Pakistan. It describes the structure and functions of the PDC, including monitoring load data across grids. It then discusses a case study where a blackout occurred in December 2020 and the strategy used to prioritize restoring 11kV feeders to defense, hospital, urban and industrial areas first. Key achievements included full restoration within 8 hours, while recommendations focus on installing new protection equipment, generation capacity and transmission infrastructure to prevent future outages.

15. Why Black Out Occurs
Power plants located at North and South part of the
country run in cascade.
There is major role of frequency while transmitting
the Power.
Frequency drops abruptly when one of the plant
trips.
Immediate action is required to disconnect the load,
otherwise other plants can be tripped due to load
with low frequency.
16. Case Study
In Dec. 2020 at 2200 Hours, suddenly blackout
occurred.
Informed to GM(OP) and worthy CEO MEPCO
about the Blackout.
Three No PTCL and Four No official Mobiles were
constantly ringing.
A lot of pressure from Public, Industrial consumers
and MEPCO field Formations.
Meeting was called with staff to set the priority of
restoration of supply of 11 KV feeders.
Repeately contacted to NPCC Islamabad, RCC
Islamabad and Jamshoro.
17. Strategy and Priority for the
Restoration of 11 KV Feeders
Defense Related Feeders.
Hospital Dominated Feeders.
Urban Area Feeders.
Industrial Feeders.
Rural / Tube well Feeders

19. PROBLEMS:-
The main problem faced was communication with
grid stations by telephone.
Due to old and manually operated circuit
breakers delay in restoration occurred.
Untrained and incompetent staff at grid stations.
Unnecessary telephone calls from higher
Authority.
19
20. ACHIEVEMENTS:-
Complete (Possible) restoration was done within 8
Hours.
Proper steps have been taken for early restoration
for stable and reliable supply to avoid public
disturbance and loss to authority.
Due to restoration in minimum time I have saved
revenue of MEPCO

21. SUGGESTIONS:-
Latest under frequency relays and other system
protection schemes should be installed.
Install new Power Plants on 220KV and 132KV
system and also increase generating capacity of
the existing Power Plants for minimum loss and
stable supply to consumers.
New 500KV and 220KV Transmission lines and
Power Transformers should be brought in
system.
Communication infrastructure should be
enhanced for prompt action.
Training must be provided to all staff to cope with
emergencies.
