Siemens Gamesa installs its offshore Direct Drive wind turbine number 1,000
Siemens Gamesa Renewable Energy (SGRE) launches the world’s first 10 MW offshore wind turbine that delivers maximum power output at all wind speeds.
Such a huge power indicator was achieved thanks to the increase in the rotor diameter to 193 meters. Moreover, the length of each individual blade is 94 meters, which is comparable to the length of one ordinary football field. The working area of the screw rotation is 29,300 m2. A system of 20 such wind turbines will be able to cover the annual energy consumption of a city the size of Ryazan or Tomsk.
Direct drive technology reduces the number of rated and wear-prone components in offshore turbines, making them easier to service. Efficiency is increased by using a permanent magnet generator. The wind turbine is equipped with a High Wind Ride Through energy generation stabilization system, which in strong wind conditions (more than 25 m / s) does not turn off the device for self-protection, but gradually reduces the output power, providing a smooth decrease in performance, which increases the stability and reliability.
The cast epoxy blades are reinforced with fiberglass to increase strength and protect against damage. Special sensors help to detect anomalies and prevent possible failures, which continuously transmit data to the control center. Siemens Gamesa plans to start commercialization of SG 10.0-193 DD wind turbines in 2022.
Earlier we wrote that the University of Lancaster invented a new version of the rotating wind turbine, which is capable of capturing wind in any direction and is optimal for working in urban environments..
