Earlier this year Vestas revealed that it was working on optimising wind energy production and lowering the cost of energy by testing a multi-rotor concept demonstrator. Today, it has been confirmed that the concept demonstrator uses the remote sensing technology from ZephIR Lidar, an approved Vestas lidar supplier.
“The installation of this multi-rotor concept demonstration turbine has enabled us to show that innovation sometimes requires new mind-sets and bold approaches“, said Jorge Magalhaes, Senior Vice President Innovation & Concepts at Vestas. “ZephIR Lidar has supported us extensively through identifying the best possible application of their unique circular scanning lidar technology to our new concept design, giving us an innovative edge that just isn’t possible through traditional techniques or other technologies.”
The Vestas concept demonstrator challenges the core scaling rules that turbines have to grow in size to increase their energy output, and also addresses transport and installation challenges in some markets. Many new load and control features will need to be developed, tested and proven to assess the technical and eventually the commercial feasibility of the concept. After a successful demonstration, Vestas will know more about the potential and possible use of the technologies. The installed ZephIR DM wind lidar will be used to accurately measure the wind characteristics, including wind speed, direction, veer and shear across the full swept area of the rotors installed on the concept design. This information will enable the ongoing development of the Vestas control strategies on the design.
Ian Locker, MD at ZephIR Lidar, was delighted at the multi-rotor launch. He commented: “This is certainly a landmark project for both Vestas and the wind industry, challenging the traditional wind turbine design constraints in a highly innovative method. ZephIR Lidar continues to support and enable innovation within the industry with our wind lidars, and we have very much become the industry standard for concept demonstrations, operating as an absolute wind measurement system with accurate and repeatable results that turbine manufactures can rely on.”
