15/50 Wind Turbine Generator
The 15/50 wind turbine generator provided by AOC is downwind type. This wind turbine does not possess an active yaw control and tracks the wind direction by utilizing its blades. This rotor deployed in this wind turbine is of hub fixed pitch type, measures 15 m in length and covers an area of 177 m². The 15/50 model incorporates a 3 phase/4 pole asynchronous generator with a rated frequency of 60 Hz and 1800 rpm. This generator uses a class F type of insulation and TEAO enclosure. The three legged, self supporting tower of this wind turbine is made of galvanized steel and measures 24.4 m. The tower is erected either on concrete or on a special anchor bolt type foundation. The PLC based control system utilized in this wind turbine monitors the wind speed, generator shaft speed, line interconnection and brake deployment.
The AOC15/50 wind turbine achieves the maximum 50 kW output at 11.3 m/s, the cut-in wind speed of this wind turbine is 4.6 m/s, its cut-out wind speed 22.4 m/s and its peak survival speed is 59.5 m/s. The annual calculated output at 5.4 m/s is 87000 kWh and at 8.0 m/s is 215000 kWh.
