Urban Wind Power: Installation of an Urban Wind Power turbine in Polhemsskolan in Gävle

##### Abstract [en]

Urban wind power is not too developed yet. Only some years ago some countries started to be aware of the important source of energy that can be used within built-up areas. The U.K., the Netherland, France and Italy are already working on it, but they are still far away to reach models and equations that can be useful for any situation.

An urban turbine is going to be installed in Gävle, Sweden, in the roof of Polhemsskolan. Therefore, the wind velocity should be found out to come up with some results about the energy yield. But some problems appear when try to estimate that velocity.

To calculate this velocity three different ways can be used. They are Mathematical models, Measurements and Simulations or Computational Fluid Dynamic (CFD) calculations. All of them are quite difficult to use. Both mathematical models and CFD are very expensive as well as they need too much time to give a result. In addition, the area where the rotor is going to be installed is quite strange and therefore, it is even more difficult to put all the data in the mathematical model or CFD. On the other hand, measurements were almost impossible to carry on. The measurement of the wind velocity should be done during one year due to the big differences in that value depending on the season; winter, summer... depending on the weather; cloudy, sunny and so on. This thesis was only four months long and that was not enough to do it. It has been tried too to use any measurements that could be in any weather stations in the surrounding of Gävle. Nothing was found. No wind velocity measurements have been made in this area.

Hence, different books and reports about this topic have been study quite depth. Most of them from the U.K. Estimations and assumptions were taking into account to come up with different solutions to make easier in the future to calculate an energy yield when measurements will be done.
