Assistance in anticipating storm damage
Modelling maps are also very helpful in the planning of maintenance arrangements for cable paths and the surrounding woods. The models enable us to prioritise high-risk areas. We can also use the maps to anticipate possible future storms. If we observe a storm approaching from a specific direction, we can anticipate the situation and repercussions more accurately. This will provide extremely useful insights in the future. On-site visits have proven that the areas indicated by the analysis really are high-risk locations. Once we finish integrating the maps fully into our own grid data system, I believe the possible applications will broaden even further.
If the power grid covers a large area, local knowledge is no longer enough to identify risky locations. Moreover, it is impossible to cover all locations with human resources alone – at least not within any reasonable time frame. The storm modelling maps have provided us with a great additional tool for determining the risk level of our power grid. I find the map itself clear and easy to understand. The risk of falling trees and resulting power line damage has been illustrated well with colours.
For us, preparing for this project was not difficult at all. We simply provided Numerola with the initial data, which they then used for the modelling and analyses. We have been very happy with Numerola’s services. They have listened to our needs carefully and stated clearly what can be done in practice. They have extensive expertise in calculation methods, which we can supplement with field-specific knowledge of the power grid sector. This collaboration has worked extremely well.
