Windmax HY400 500 Watt Max 12-Volt 5-Blade Residential Wind Generator Kit
$649.00 Advantages of 5-blade wind turbines over 3-blade wind turbines 1) 5-blade wind turbines will greatly improve annual energy production in low wind conditions. For areas with average wind speeds of 11 MPH (5m/s). If you compare annual energy output to conventional 3-blade wind turbine, there is an increase of annual energy output of more than 60%. 2) 5-blade wind turbines will dramatically improve ... |

Windmax HY600-3 750 Watt Max 24-Volt 3-Blade Residential Wind Generator Kit
$769.00 A wind turbine is a long term investment. Before you purchase a wind turbine, the first factor to consider is if the energy produced by a wind turbine can pay for itself in 10 years or less. The second factor to consider is installation and ownership cost. Poor reliability, low quality and high maintenance will greatly increase ownership cost and make the wind turbine impossible to pay for itself... |

Wind Turbine Control Systems
$125.98 Modern wind turbines generally operate at variable speed in order to maximise the conversion efficiency below rated power and to reduce loading on the drive-train. In addition, pitch control of the blades is usually employed to limit the energy captured during operation above rated wind speed. The higher complexity of variable-speed variable-pitch turbines is offset by the benefits of control flexibility, namely, higher conversion efficiency, better power quality, longer useful life; because of the immediate impact of control on the cost of wind energy, reliable high-performance controllers are essential in making wind technology competitive. In Wind Turbine Control Systems the application of linearparameter varying (LPV) gain scheduling techniques to the control of wind energy conversion systems is emphasised. This recent reformulation of the classical gain scheduling problem allows a straightforward design procedure and simple controller implementation. The monograph provides a thorough coverage of wind turbine control, including: â?¢ an overview of the principles of wind energy conversion; â?¢ the control-oriented modelling of wind turbines; â?¢ an in-depth analysis of the most common control strategies; â?¢ the design of LPV gain-scheduled controllers for both fixed- and variable-pitch, variable-speed wind turbines. Wind Turbine Control Systems is primarily intended for researchers and students with a control background wishing to expand their knowledge of wind energy systems. The book will be useful to scientists in the field of control theory looking to apply their innovative control ideas to this appealing control problem and will also interest practising engineers dealing with wind technology who will benefit from the comprehensive coverage of the theoretic control topics, the simplicity of the models and the use of commonly available control algorithms. |
