    Overview of Wind Energy Systems: Issues in Development and Application (1981)
    American Society of Mechanical Engineers
    Details
    Publikationsdatum: 1981-02-01
    Beschreibung: An overview of the current status of wind energy technology and system development is presented with major emphasis placed on the key issues which face the commercialization of wind technology. The basic fundamentals of the technology are reviewed and the direction of current development is outlined. Economic considerations are discussed both from a machine development point of view and the utility-industry cost-of-service approach. In addition, the problems associated with wind turbine performance testing are discussed and a short review of operational experience is provided. These topics are all considered in the context of providing the reader with an understanding of wind system technology, a general knowledge of current problems, and the expected trends for the future. Many of these important issues are still under intensive investigation, and in some cases, a clearly superior solution has not emerged. In these circumstances, the value judgments are properly left to the reader.

    Structural Dynamic Analysis of Wind Turbine Systems (1982)
    American Society of Mechanical Engineers
    Details
    Publikationsdatum: 1982-05-01
    Beschreibung: The paper presents an overview of the dynamic analysis of horizontal axis wind turbines. The major emphasis of the paper is the review of current analysis methods and the comparison of results with experimental data. The current capabilities for predicting turbine system natural frequencies are discussed and the design implications of frequency placement are reviewed. The prediction of cyclic loads, using the dynamic analysis computer codes, is examined and comparisons are made between the code predictions and field test data. Finally, the dynamic analysis needs for advanced turbine systems are considered.

    Wind turbulence inputs for horizontal axis wind turbines (1981)
    In:  CASI
    Details
    Publikationsdatum: 2016-06-07
    Beschreibung: Wind turbine response characteristics in the presence of atmospheric turbulence was predicted using two major modeling steps. First, the important atmospheric sources for the force excitations felt by the wind turbine system were identified and characterized. Second, a dynamic model was developed which describes how these excitations are transmitted through the structure and power train. The first modeling step, that of quantifying the important excitations due to the atmospheric turbulence was established. The dynamic modeling of the second step was undertaken separately.

    Wind response characteristics of horizontal axis wind turbines (1981)
    In:  CASI
    Details
    Publikationsdatum: 2019-06-28
    Beschreibung: It was the objective of the work reported here, and in the companion paper 1 . A broader examination of wind turbine dynamic response to turbulence, and attempts to ascertain the features of turbulence that wind turbines are most sensitive to were made. A statistical description of the wind input including all three wind components and allowing linear wind gradients across the rotor disk, was used together with quasi-static aerodynamic theory and an elementary structural model involving only a few degrees of freedom. The idea was to keep the turbine model simple and show the benefits of this type of statistical wind representation before attempting to use a more complex turbine model. As far as possible, the analysis was kept in the simplest form, while still preserving key physical responses.

    Wind Turbine Dynamics (1981)
    In:  CASI
    Details
    Publikationsdatum: 2019-06-28
    Beschreibung: Recent progress in the analysis and prediction of the dynamic behavior of wind turbine generators is discussed. The following areas were addressed: (1) the adequacy of state of the art analysis tools for designing the next generation of wind power systems; (2) the use of state of the art analysis tools designers; and (3) verifications of theory which might be lacking or inadequate. Summaries of these informative discussions as well as the questions and answers which followed each paper are documented in the proceedings.

    Atmospheric turbulence parameters for modeling wind turbine dynamics (1982)
    In:  CASI
    Details
    Publikationsdatum: 2019-06-28
    Beschreibung: A model which can be used to predict the response of wind turbines to atmospheric turbulence is given. The model was developed using linearized aerodynamics for a three-bladed rotor and accounts for three turbulent velocity components as well as velocity gradients across the rotor disk. Typical response power spectral densities are shown. The system response depends critically on three wind and turbulence parameters, and models are presented to predict desired response statistics. An equation error method, which can be used to estimate the required parameters from field data, is also presented.

    Publikationsdatum: 2019-07-13
    Beschreibung: The proceedings of a workshop held in Cleveland, July 28-30, 1981 are described. The workshop emphasized recent experience in building and testing large propeller-type wind turbines, expanding upon the proceedings of three previous DOE/NASA workshops at which design and analysis topics were considered. A total of 41 papers were presented on the following subjects: current and advanced large wind turbine systems, rotor blade design and manufacture, electric utility activities, research and supporting technology, meteorological characteristics for design and operation, and wind resources assessments for siting.
