WES18 Mid-Sized Wind Turbine from WES Canada

WES Canada provides the WES18 a midsized wind turbine. This wind turbine incorporates a two-bladed rotor with passive pitch, an OGBT converter and a synchronous generator.

The rotor of this wind turbine measures 18 m and the carbon and fiber reinforced epoxy blade measures 7.8 m in length and weighs less than 100 kg. The strong and flexible blades are coated with non-corrosive paint and a shock absorbing coating at the leading edges. The upwind positioned blades rotate in clockwise direction at a variable 60–120 rpm and cover a spanned area of 254 m².

The WES18 a midsized wind turbine offered by the WES Canada is available in tower lengths measuring 18, 24, 30 or 39 m made of hot-dipped galvanized steel. The 39 m tower is conical in shape while towers of other sizes are made from straight pipes. The nacelle installed at the top of the tower incorporates the generator, gearbox, control system and the yaw-system. The two stage FLENDER gearbox has 1:20 speed ratio to increase the speed of the rotor and stops the running of the blades by utilizing a blocking device. The four-pole, brushless, synchronous generator utilized in the model is not affected by fluctuations in the wind speed and functions without maintenance.

The WES18 wind turbine from WES Canada has a cut-in wind speed of <3 m/s, a cut-out wind speed of 25 m/s, a nominal wind speed of 13 m/s and a survival wind speed of 60 m/s, noise emission at 8 m/s speed and at 100 m distance is  measured as 45 dB and this wind turbine operates in -20°C up to +40°C
