Gamesa trio win innovation award

Gamesa has awarded an innovation prize to a trio of its engineers for an anti-icing paint for rotor blades.

Bladeshield, developed for onshore and offshore turbines by María Yoldi, Rosario Ortigosa and Almudena Muñoz, prevents the formation of ice and protects the blade coating’s against erosion.

"The goal is to further improve wind turbine reliability and availability as part of our bid to continually bring down the cost of energy,” says Gamesa chief technology officer José Antonio Malumbres.

The novel coating is based on the development of a breakthrough procedure for concocting the mix, with the additive dissolved first in a dispersing agent and then in the paint base.

This results in a homogenous mix that can "double" a blade's anti-erosion and durability properties.

A second prize went to a rotor inertia management system, devised by Gamesa chief electrical engineer Francisco Jiménez Buendía, which detects changes in the frequency in the power grid so that turbines can make a split-second injection of energy stored in the powertrain to prevent a stall.

Before now, this boost did not happen until 30 seconds after the disruptive event.

The awards were made as part of Gamesa's Patents and Inventors Competition, which is designed to acknowledge its employees’ efforts to develop innovations "with the potential to set the company's technology offering apart".
