According to the team, they found that the most efficient strategy could be to pick a fraction of towers from the highest wind speed zones (according to the Indian standards) that are associated with substations serving a large population.
Researchers at the Indian Institute of Technology (IIT), Gandhinagar, have developed a comprehensive framework that can reduce the damage to power transmission systems in coastal areas under cyclone scenarios. The team used damage-cum-wind speed data of Cyclone Fani in Odisha to develop a fragility model for towers, which helps assess the functionality of the network and the influence of strategic interventions on the same.
According to the team, they found that the most efficient strategy could be to pick a fraction of towers from the highest wind speed zones (according to the Indian standards) that are associated with substations serving a large population.
Strengthening towers nearest to the coast may somewhat help reduce the number of towers damaged during a cyclone, but its resultant impact on the affected population may not be as significant.
The study results revealed that a greater number of reinforced towers or a greater level of strengthening in them based on tailor-made and efficient reinforcement prioritisation strategies in a particular region leads to better functionality of power transmission systems.
