Constraints to medium voltage power cables in wind farms
(This post has been updated in July 2020 with the help of my friend and colleague Kamran) I already discussed in two other posts how the wind farm cable trenches are usually built and how the medium voltage cables are made. However, a more comprehensive explanation should include on how the medium voltage cables are dimensioned. The power produced…

How to measure wind resource
I have to start with a disclaimer – I’m not a specialist in wind resource analysis. However, through the year I’ve seen several time this process so I think I can summarize it with a reasonable level of accuracy (and obviously if you spot a mistake, please let me know). The wind resource assessment is…

Wind sector management – how to put more wind turbines in the same area
In many project my colleagues from the wind and site department (the people who calculate the best wind turbine model and the optimal layout in a wind farm) are forced to put quite a lot of wind turbines in a reduced space. Each of these wind turbines generate a “wake effect” – basically, they create…

Dynamic loads on wind turbines
I discussed in another post the relevance of resonance analysis in the design of steel tower for wind turbines and the different technical solutions currently in the market. But what are the loads that could induce resonance in the wind turbine? There are several different type of dynamic loads: Unbalanced rotor. This basically means that…
