Notable applied research projects

LIDAR validation with NRG Systems/Léosphère, GL Garrad Hassan and the École de technologie supérieure (ÉTS)

LIDAR technologies offer great potential to wind energy producers by reducing wind measurement uncertainty which in turn reduces the related capital investment risk. The LIDAR WINDCUBE v2 is an instrument currently used in the wind energy industry. For it to be considered "bankable" for measurement in complex settings and northern climates, it must be shown to function properly in such conditions.

The TechnoCentre éolien set up and commissioned a WINDCUBE v2. This project serves to develop and validate data analysis methods as well as to analyse the resulting data and compare them to data measured by conventional measurement instruments.

Wave quality measurement with the Hydro-Québec Institut de recherche (IREQ)

Given the context of a growing wind energy production network in Québec, Hydro-Québec Distribution plans to connect several wind farms – with installed capacities of up to 25 MW – to power distribution lines already connected to its customers. To preserve the quality of its power supply and the product delivered to its customers, Hydro-Québec Distribution is committed to ensuring, notably, maintenance of the quality of the electrical wave on its lines after the wind farms have been connected.

The TechnoCentre éolien is accompanying IREQ as it validates the method used to predict the impacts of wind turbines on wave quality by performing measurements at the Rivière-au-Renard research site and to validate flicker mitigation by regulating the power factor.

Development of a visual ice detection system with the Centre de Robotique et de Vision Industrielles (CRVI)

The accumulation of ice and frost on the blades of a wind turbine has serious harmful consequences for the operation of wind turbines in several ways. First, alteration in the dynamic profiles of blades causes significant loss of electrical productivity. In addition, the weight of the ice and the resulting dynamic imbalance can induce mechanical loads that can be very damaging to the structural integrity of the wind turbine.

Given this, our industrial partner REpower Systems inc., a world leader in the wind turbine field, wants to develop a system that can be used to visually detect ice on the blades of its wind turbines for analysis purposes and ultimately, develop ice protection solutions.

The TechnoCentre éolien, working with the Centre de Robotique et de Vision Industrielles, is developing a machine vision system that will automatically detect the accumulation of ice on wind turbine blades.

The TechnoCentre éolien also works on applied research projects subject to confidentiality agreements with the enterprises involved.
