Vestas has produced the initial kilowatt-hour from its multi-rotor wind turbine demonstrator in Denmark.
The manufacturer said the milestone at the Riso laboratory site followed “satisfactory results of necessary tests”.
The machine, which features four nacelles supported by a single tower, will continue to be put through its paces.
“Right now we are testing various software functions. One of them is the cut-out functionality, ie if the concept demonstrator stops when it reaches the cut-out wind speed.
“Another one is the yaw system supervision that shuts down the turbine in case the yaw misalignment exceeds certain values,” said Erik Carl Lehnskov Miranda, senior specialist for electrical, load and control at Vestas.
The turbine, which was erected in spring, features refurbished V29-225kW nacelles. Full-scale convertors and control features have been added to enable required testing. Tip height is 74 metres and tailored to site-specific requirements.
Vestas said when announcing the project that it “challenges the core scaling rules that turbines have to grow in size to increase their energy output”.
