Abstract

The present subject matter discloses a method of measuring a peak load, including the steps of placing an indenter between a first surface and a second surface, exerting a load on at least one of the first and second surfaces, measuring at least one of a width, depth, radial chord length, and cross-sectional area of an indentation formed by the indenter in at least one of the first and second surfaces; and converting the measured parameter into a load value. Certain methods further include the steps of converting the measured parameter into a load per length value and obtaining a load value by integrating along a circumferential length of the indentation. In still other methods, the exerted load is a compressive load.

Method and apparatus for reducing rotor blade deflections, loads, and/or peak rotational speed

Patent Moroz, Emilian Mieczyslaw; Pierce, Kirk Gee

A method for reducing at least one of loads, deflections of rotor blades, or peak rotational speed of a wind turbine includes storing recent historical pitch related data, wind related data, or both. The stored recent historical data is analyzed to determine at least one of whether rapid pitching is occurring or whether wind speed decreases are occurring. A minimum pitch, a pitch rate limit, or both are imposed on pitch angle controls of the rotor blades conditioned upon results of the analysis.

Methods and apparatus for reducing peak wind turbine loads

Patent Moroz, Emilian Mieczyslaw

A method for reducing peak loads of wind turbines in a changing wind environment includes measuring or estimating an instantaneous wind speed and direction at the wind turbine and determining a yaw error of the wind turbine relative to the measured instantaneous wind direction. The method further includes comparing the yaw error to a yaw error trigger that has different values at different wind speeds and shutting down the wind turbine when the yaw error exceeds the yaw error trigger corresponding to the measured or estimated instantaneous wind speed.

Load controller and method to enhance effective capacity of a photovoltaic power supply using a dynamically determined expected peak loading

Patent Perez, Richard

A load controller and method are provided for maximizing effective capacity of a non-controllable, renewable power supply coupled to a variable electrical load also coupled to a conventional power grid. Effective capacity is enhanced by monitoring power output of the renewable supply and loading, and comparing the loading against the power output and a load adjustment threshold determined from an expected peak loading. A value for a load adjustment parameter is calculated by subtracting the renewable supply output and the load adjustment parameter from the current load. This value is then employed to control the variable load in an amountmore » « less

Method and apparatus for current-output peak detection

Patent De Geronimo, Gianluigi

A method and apparatus for a current-output peak detector. A current-output peak detector circuit is disclosed and works in two phases. The peak detector circuit includes switches to switch the peak detector circuit from the first phase to the second phase upon detection of the peak voltage of an input voltage signal. The peak detector generates a current output with a high degree of accuracy in the second phase.
