The Design of Smart Wind Turbine Rotors
Context of the research
The research is carried out within the framework of the European Research Program named Upwind, in which many universities, research institutes and companies join, forming a huge multi-disciplinary group. The work package in which this research project is currently involved has the subject “Smart Rotor Blades and Rotor Control”
The research topic will focus on the design of “smart” rotor blades, i.e. blades with integrated aerodynamic control devices that can be controlled actively and independently. With the combination of advanced materials, actuators, sensors and controllers this smart control concept will operate in a way that fulfils the required strategy (e.g. alleviation of fast fluctuating fatigue loads).
Objectives of our research
The objective of our research is:
-Prove the feasibility of significant blade load alleviation by applying spanwise-distributed smart load control devices through models and experiments.
-Provide design guidelines for smart wind rotor wind turbines.
The research therefore involves the investigation of smart material and devices, the development of new aerodynamic /aeroelastic rotor design models and new control algorithms, and the integration of all in smart rotor design. Mainly, research is focusing on aerodynamic modeling. Cooperation with other partners from UpWind and STW projects provides a complete approach to the subject, involving research in aerodynamics, dynamics, materials and control/identification.
Methodology – Progress so far
Until now, the research is directed towards the investigation of smart actuator options, design requirements and aerodynamic modelling of control devices. A multidisciplinary database of state-of-the art knowledge has been organised. Aeroelastic models are being developed for the simulation of a smart rotor. Different concepts of actuation are being investigated. Also, a first experimental approach of a non-rotating smart blade is being prepared. In this upcoming experiment, the feasibility of load alleviation by the application of a smart active control system integrated on a blade will be shown.
In the near future a rotating experiment of a “smart” wind turbine will be performed at the OJF wind tunnel, new design codes for smart rotor design will be delivered, most promising solutions will be suggested and all design details of such a concept will be covered.
