Norwegian company Statoil, along with the Arabic Masdar 18 October ushered in the Scottish Aberdeenshire the world’s first floating wind farm Hywind. As reported by a Norwegian company, the new plant with a capacity of 30 megawatts earned in the sea 25 km from the coast. Electricity from it goes to the grid of the city of Peterhead.
As noted, N+1, the coast and marine areas more remote from it, there is an advantage to placing wind farms. Because of the temperature contrast between water and land here there are often air flow is sufficient to generate electricity power.
Floating wind farm in Scotland comprises of five wind turbines. The height of the mast of the wind turbine of 175 m, and its weight is about 12 tons. The wind turbine is equipped with a screw with three blades, the length of each of which is 75 m.
The mast of the wind turbine is installed on the extended float with a length of 78 m, which as a stabilizing ballast used iron ore. In addition, the float under water is held by three flexible cables fixed to the bottom by using a heavy 60-ton blocks.
The angle of the blades of the propellers of the wind turbine may vary. It defines a special control software, which calculates the desired angle depending on the strength of pitching and wind. In the future, Statoil and Masdar intend to provide a floating power station in Scotland Li-ion battery with a capacity of one megawatt-hour.
The developers believe that the battery will allow you to accumulate energy and to serve as a buffer during peaks of energy consumption. Battery for floating wind power plants received the name Batwind.
In addition to the Scottish Hywind currently under construction is similar to floating power plants off the coast of the U.S. state of Maine and the coast of Spain. Formally, the world’s first floating power plant was the experimental station off the coast of Norway. It’s been tested in 2009-2011. It works today, but the EB is not connected and is used to Refine the technology.
In early June of this year, the Makani division of the American company Google has tested a new wind turbine, made in the form Cordoba glider. New flying turbines will have to soar to the heights, where almost ever-present wind to produce electricity.
The device, made in the form of a plane, will be the special cable is connected to ground. A wind turbine having a wing span of 25.9 meters, will rise to a height of 305 meters. The device is equipped with eight small generators connected to the propellers with a diameter of 2.3 meters each. Power tested flying vetrogeneratory amounted to 600 kilowatts.
