Medium voltage power cables in wind farms: an introduction
This post is an extension of the previous short article I wrote some years ago on the characteristics of wind farms medium voltage system. I wrote it with the help of my friend and colleague Kamran, who spent more than an hour answering my questions on the subject. Thank you Kamran! The medium voltage network…

Cable trenches layout design
We try to design cable trenches as straight as possible, avoiding pronounced angles. There are several national norms on the minimum bending angle, for instance UNE 20435/2 in Spain. For environmental and technical reasons we try to design the trench parallel to the access road. When we have to cross an obstacle such as an…

Medium Voltage Cables Optimization
The optimum design of the medium voltage (MV) cables consists in finding the best compromise between the initial cost of the cables and the total energy loss of the system. For this reason we design wind farms with a radial network, and section of the cables decreasing from substation to the most faraway point of…
