Wind Turbine Components

The major components of the FD5KW wind turbine are shown in Figure 1.

 

Blades/Rotor System

The rotor system consists of three fiberglass blades. Acting like aircraft wings, the blades convert the energy of the wind into rotation forces that can drive a generator. The rotor has three blades because three blades will run much smoother than rotors with two blades. The dogvane on the turbine can, together with the micro processor in the controller, push the rotor over to the side, away from the wind.

Alternator

The alternator converts the rotational energy of the rotor into electricity. The alternator utilized permanent magnets and produces three phase AC electric power. The internal windings and central shaft rotate, while the outside housing are stationary. The alternator was specially designed for the FD5KW and produces power at low speeds of 2m/second only. Eliminating the need for a speed increasing gearbox.

The output from the alternator is three-phase alternating current (AC), but it is rectified to direct current by the charge controller. Since it uses permanent magnets, the alternator is generating voltage whenever the rotor is turning.

Nacelle

The nacelle is the steel housing around the main body of the machine. It contains the main structural backbone of the turbine (called the mainframe), the slip-ring assembly, the yaw bearings and the tower mount. The yaw bearings allow the wind turbine to freely pivot around the top of the tower so that the rotor will face into the wind.

The slip-ring assembly is the electrical connection between the moving(as it orients with the wind direction) wind turbine and the fixed tower wiring. The slip-rings and yaw bearings are located just above the tower mount. The tower mount attaches the FD5KW to the top of the tower.

High wind protection system

The high wind protection system composed of a dogvane, anemometer and a micro processor which is inside the controller box. The dogvane is mounted on the nacelle (Figure 25), while the anemometer can be mounted on the building roof or anywhere high above the ground (Figure 33). During periods of high wind speeds(wind speed over 25 m/s), the anemometer detects it and send a message to the micro processor inside the controller which instruct the dogvane on the turbine and a DC motor against the turbine yawing. The rotor will turn over to the side, away from the wind, thus reducing the power output significantly. The rotor is kept facing into the wind at speeds up to 25 m/s, therefore the rotor will rotate again once the wind

speed falls down 25 m/s.
