End report ID3AS AirOPT

Large wind turbines have recently had the energy sector’s attention given their reliability, cost-effectiveness, competitive power, and the maturity of their technology. Unfortunately, large wind turbines usually face obstacles regarding their social acceptance near rural or residential areas. On the other hand, small wind turbines are better accepted in these areas as their presence is perceived as less threatening. For this, Tandem Wind Energy (TWE) has developed a small wind turbine concept that would be robust, reliable, and affordable. The TWE turbine shall especially target rural areas in developing countries where the access to the grid is limited. To ensure that the turbine will deliver as promised, the turbine has been heavily instrumented with different sensors on the rotor and the tower to measure its performance. Prior measuring its performance, a simulation model was developed by the Emden/Leer consortium team members to estimate the aerodynamic performance of the wind turbine. The output of this model would be validated against the measurements from the test site. The wind turbine was then assembled and erected successfully at the Hanzehogeschool test site. The wind turbine concept has proven to be successful yet due to complications, the test field measurements could not be obtained in time, which shall result in the continuation of the analysis beyond the ID3AS project in 2021.
