Offshore wind farm, Alpha Ventus, has delivered its first run of power to the German national grid. Five out of 12 turbines have been completed, three of which are in their adjustment phase, all of which are due to be fully functional by the end of this year.
Composite materials are used in the construction of the rotor blades at the Borkum-based Aplha Ventus project.
According to project leaders, this is the first time offshore wind power has been used in the North Sea to assist Germany’s power demands.
The turbines, with a nominal capacity of five megawatts, are located 45 kilometres north of the island of Borkum.
“The wind turbines ‘AV 8’, ‘AV 9‘ and ‘AV 12’ are currently undergoing the so-called adjustment phase“, explains Wilfried Hube, the overall project leader of alpha ventus.”As the name suggests, during this phase all the functions of the turbines are technically inspected and adjusted for the subsequent long-term operation. This is comparable with making technical adjustments to the engine of a new car,” continues Hube.
The adjustment phase is followed by a period of so-called trial operation. In this phase, the wind turbines are subjected to various test scenarios, such as operating under full load at different wind speeds. These test scenarios last for several hundred hours.
Construction of the wind turbines began in mid-April this year, after a first attempt had to be aborted in August 2008 due to poor weather conditions.
