How do offshore wind turbines generate electricity? You probably know that wind turbines produce electricity from wind. But how do they do it Let’s take a look at this
particular offshore wind turbine. Sensors on top of the turbine
measure wind speed and direction They signal the yaw-motors in which direction to turn
in order to point the nose in the wind. The kinetic energy in the wind causes the blades of the rotor to rotate. The rotor drives the low speed shaft and by using a gearbox, the speed of the shaft is amplified. This high-speed shaft drives the generator which converts the kinetic energy into electricity. A frequency converter synchronises the generated electricity to the grid. Subsequently a transformer amps up the voltage before the electricity is transmitted. It then goes through subsea-cables to a substation to which several arrays of wind turbines are connected. At this substation the voltage amps up even more to minimize transmission losses. Finally it is then transmitted into the mainland power-grid. From the main power-grid the energy can be used to power hospitals, charge electric vehicles or turn on light bulbs. And this is how offshore wind turbines generate electricity. We hope you enjoyed our 60 second lecture.
