Al Fujaij Wind Turbine:
As part of the Wind Energy and Concentrating Solar Power Project (WECSP) project:
A 1.65 MW wind turbine is installed at Al-Fujeij site which is part of the TWT-1.65 wind turbine family from MTOI- Spanish Company. The TWT-1.65 wind turbines have active pitch power control and variable rotor speed.
Its electrical machine is a multi-pole variable speed synchronous generator connected to the grid through an electrical converter to supply 1650kW active power; the wind turbine is able to generate reactive power up to cosPhi 0.9, both capacitive and inductive. The generator couples directly to the rotor main shaft with no gearbox.
The turbine rotor has three blades located upwind (in front of the tower). The machine has an auxiliary mechanism for the nacelle orientation (yaw system) to keep the rotor aligned towards the incident wind direction. Rotor blades have pitch mechanisms to regulate the output power constant above the rated wind speed.
The control system monitors and controls all the wind turbine functions and the turbine is built on a tubular steel tower with a total hub height of 71m.
