  • IECON – Development of Hybrid Blade Angle Control System for Traversing Wind Turbines
    IECON 2018 – 44th Annual Conference of the IEEE Industrial Electronics Society, 2018
    Co-Authors: Tomonobu Furuta, Hiroyuki Kawai, Masato Okamoto, Kenji Kubomura

    Abstract:

    In this paper, we consider a Passive-type Traversing Wind Turbine (PTWT) and propose a control system to improve power generation and windbreaker effect of the wind turbine. Wind power has been becoming more popular worldwide and several types of wind turbines to match different operating environments and objectives have been researched. As one of them, we have started to study a special type of Vertical-Axis Wind Turbine (VAWT) which may also solve wind disaster problems in agricultural areas. The parallel mechanism in this type of wind turbine makes it difficult to adjust Blades Angle, therefore the mechanism has trouble changing Blade Angle during sudden inversions in wind direction. However, by using a passive mechanism that only uses the power of the wind, the wind turbine can keep up with sudden inversions in wind direction. In addition, active control is possible by attaching actuators, and hybrid control (passive and active) may increase the efficiency of power generation and windbreaker effect. We conduct wind-tunnel tests to evaluate the incleased effectiveness of power generation using the hybrid control system. Additionally, we investigate drag of the wind turbine to clarify the windbreaker effect using the developed system.

  • A Data-Driven Approach for Monitoring Blade Pitch Faults in Wind Turbines
    IEEE Transactions on Sustainable Energy, 2011
    Co-Authors: Andrew Kusiak, Anoop Verma

    Abstract:

    A data-mining-based prediction model is built to monitor the performance of a Blade pitch. Two Blade pitch faults, Blade Angle asymmetry, and Blade Angle implausibility were analyzed to determine the associations between them and the components/subassemblies of the wind turbine. Five data-mining algorithms have been studied to evaluate the quality of the models for prediction of Blade faults. The prediction model derived by the genetic programming algorithm resulted in the best accuracy and was selected to perform prediction at different time stamps.
