Preamble Preamble

Bangladesh is identified as a natural disaster prone area in the globe. Due to geographical situation and climate, natural disaster is a common scenario in this country. In comparison with earthquake risk maps of the USA, Bangladesh is comparatively less Seismic than

California. For Design purpose, in the coastal area, wind velocity is

considered as 250 Km/hour and surge height is 10~15 meter. Mitigation and preparedness is the only way to face the challenges of disaster.

Extent of Major Disaster i Extent of Major Disaster in Pow er Sector Pow er Sector

Cyclone In 1988 and in 1991, devastating cyclone damaged the distribution system of Western and Southern Zone

f Bangladesh respectively. Small

Diesel Power Stations & Power System in offshore islands were completely washed away by storm surge. Flood In 1988 and in 1998, a few number of substations (Ullon, Moulavibazar, etc ) were inundated due to severe flood. Earthquake In 2003, earthquake damaged bushing

f the Power Transformer &

Transformer itself at Modunaghat Grid Sub Station in Chittagong and damaged School building of Karnaphuli Hydro Power Station at Kaptai.

Disaster /Securi Disaster /Security Plan for Pow er Sector y Plan for Pow er Sector

Alert and Warning Phase –

Designating a focal point for disaster management.
Set up central / local control room.
Set up communication with all bases.
Mobilize manpower, transport, tool and maintain emergency lines.
Set up standing committee centrally and base level at affected areas.
Electric lines to shut off to prevent accident.
Keep ready in stock emergency electrical material.

Disaster Phase -

Run the Control Room round the Clock
Ensure speedy supply of material

Recovery Phase -

All efforts to restore power supply
Assess the fund required for restoration and rehabilitation
Prepare plan for rehabilitation

Present Communication System of Present Communication System of Pow er Sector Pow er Sector

For day to day routine works and system operation Power Sector maintains its

wn communication system called Power Line Carrier (PLC) Communication

using its high voltage transmission lines connecting all the power plants and high voltage sub-stations (230 KV& 132 KV) with the Load Dispatch Center. The functions include Telecommunication, Tele-protection, Data-transmission, Supervisory Control and Data Acquisition (SCADA) , Economic Load Dispatching etc. The frequency band of the existing PLC communication system is very low (100 Khz to 500 Khz) and its speech band is only 4 Khz. To overcome the low bandwidth limitation and to expand communication system, installation of optical fiber over high voltage transmission lines throughout the whole country is going on. Until now about 500 Km optical fiber (single mode) has already been installed around Dhaka and Dhaka to Chittagong route as OPGW (Optical Ground Wire) without having any terminal equipment.

Microw ave System Microw ave System

One Microwave link between Faridpur and Manikganj has been planned to make redundancy in case of disruption of Sirajganj – Ashuganj Optical link between the East and West part of the country. The link is approximately 38 Km in length and crosses the Padma river (the aerial distance is roughly 5 Km). The link shall operate in the 7.5 GHz band and shall carry one or more STM-1 Signals.

Conclusion Conclusion

During Disaster, PLC of the power sector could be a good choice for emergency communication, where normal Tele-communication will be impossible. To extend the service of PLC system as backup communication during disaster especially in the costal belt, microwave link with the PLC system may be considered. The Optical network of Power Sector will be much reliable and safe in comparison to other Optical Fiber Network because this optical network has been installed over the high voltage transmission line and so it is free from most of the unwanted interruptions.
