    The global wind-energy resource is very large and widely distributed; and, within Europe, wind energy has the potential to provide an energy output equal to about three times the present electricity consumption. Although the wind is not very reliable as a source of power from day to day, it is a reliable source of energy year by year, and the main role for future wind-energy systems will be operat...

  • Estimation of low-level winds from upper-air data

    Publication Year: 1983, Page(s):517 - 522
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (932 KB)

    Estimates of winds at heights of around 100 m are required for the siting of large wind turbines. Because of uncertainties often attached to the normal method of extrapolating from data at 10 m, a method of extrapolating from upper-air data has been developed. The predictions of this method are compared with measurements at several stations on land and one offshore. View full abstract»

  • Dynamics of wind turbines

    Publication Year: 1983, Page(s):523 - 530
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1104 KB)

    Three principal aspects of the dynamics of wind-turbine behaviour are discussed: forced response to deterministic loads, forced response to stochastic loads and stability. In each case, an introduction to the physics of the problem is presented and a means of analysis is described. A simple analytical model is derived to help illustrate some of the analytical techniques commonly employed. View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (864 KB)

    Recent Canadian progress in the development of the curved-blade Darrieus vertical-axis wind turbine (VAWT) is described. Co-operation between government, industry and power utilities in the conduct of field trials, over several years, has demonstrated inproved performance and reliability of grid-coupled turbines of this type. The rated power of the VAWTs currently under test ranges from 30kW, in a... View full abstract»

  • Wake structure measurements at the MOD-2 cluster test facilty at goodnoe hills, Washington

    Publication Year: 1983, Page(s):562 - 565
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (525 KB)

    A field measurement programme was carried out at the cluster of three MOD-2 wind turbines located at Goodnoe Hills, Washington, to determine the rate of decay of wake velocity deficit with down-wind distance in various meteorological conditions. Measurements were taken at hub height (60 m). Wake wind speeds were measured using a radiosonde suspended from a tethered balloon, its position being dete... View full abstract»

    The feasibility of constructing large arrays of wind turbines (100¿¿1000 machines) has now been firmly established. The energy losses are predictable, and can be kept below 20¿¿25% with suitable choice of spacing. The energy yields of clusters have been calculated so as to quantify the UK offshore windpower resource, and estimates have also been made as an input to assessments of the problems and ...

  • Risks associated with wind-turbine blade failures

    Publication Year: 1983, Page(s):574 - 586
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1716 KB)

    The CEGB is investigating the potential of large wind turbines for generating electricity. The paper considers the risk to people and property, in the unlikely event of a serious structural failure of the main rotor. The greatest risks are found very close to the machine, typically within one blade diameter of the tower base. Outside this area, the overall probability of being struck by a blade is...

  • Dynamics of an isolated power system supplied from diesel and wind

    Cited by:  Papers (8)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (888 KB)

    To investigate the feasibility of 100% wind penetration in diesel-wind power supplied isolated networks, a computer simulation program was developed. To maximise wind-power contribution, the steady-state operating conditions are optimised within the limits imposed by engineering constraints and voltage and frequency deviations. The dynamics of the system are simulated and a control policy is devel... View full abstract»

  • Modelling and control of a wind-driven induction generator for water storage heating

    Publication Year: 1983, Page(s):596 - 603
    Cited by:  Papers (3)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (761 KB)

    The paper discusses the concept of using a self-excited induction generator, driven by a wind turbine for water storage heating. An accurate mathematical model of the generator is used to establish, as functions of angular velocity, the particular variations of excitation capacitance and load resistance, which simultaneously cause the turbine to run at optimum tip-speed ratio and maximise the gene...

  • Wake and performance measurements on the Lawson-Tancred 17 m horizontal-axis windmill

    Publication Year: 1983, Page(s):604 - 612
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1189 KB)

    Existing estimates of the efficiency of clusters of wind turbines are principally based on wake data derived from small-scale wind-tunnel tests. Measurements of the wake at 1D and 2.5D downstream of an intermediate size windmill are described here. Centre-line velocity deficits of 0.74 and 0.44, respectively, are found. Even at 1D the wake profile is closely Gaussian. Limited data on the aerodynam... View full abstract»

    A large potential demand exists for electricity in areas isolated from grid supply. Diesel generation in these usually remote areas is expensive and wind/diesel systems, with the wind turbine viewed primarily as a fuel saver, can be seen as attractive. Integration of wind energy is not straightforward, and in particular can cause operational problems for the diesel generator set. These difficultie... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (992 KB)

    Environmental issues relating to the introduction of large, MW-scale wind turbines at land-based sites in the UK are discussed. Areas of interest include noise, television interference, hazards to bird life and visual effects. A number of areas of uncertainty are identified, but enought is known from experience elsewhere in the world to enable the first UK machines to be introduced in a safe and e... View full abstract»
