The Wind Energy Institute of Canada (WEICan) operates a commercial, grid-connected 10 MW R&D wind farm. WEICan’s site includes five 2 MW wind turbines manufactured by DeWind. DeWind were a German turbine manufacturer and are no longer in existence. Each wind turbine has a 2 MW, four pole synchronous generator directly connected to the grid. No power electronics are used between the generator terminals and the power grid. The turbines have a rotor diameter of 92 m and a hub height of 80 m. Blade pitch is hydraulic. A two stage gearbox is used between the rotor and the torque converter. A torque converter (WinDrive from Voith) is used between the gearbox and the generator. The WinDrive provides a fixed 1800 rpm output to the generator shaft.WEICan’s site also has a 109 kW solar PV array with a mix of bifacial and monifacial panels. WEICan recently installed a 111.5 kw / 223 kWh Tesla Li-ion battery.
