Power Estimation Algorithm for High-Power Wind Turbines with Time Variable Wind Speed

Abstract

Using data from measurements (wind speed and wind turbine speed values), this study analyzes under what conditions maximum wind energy is gathered at a wind turbine operating at wind speeds that change substantially over time. The wind energy variation in time is calculated by measuring the wind speed, which may also be visualized by showing the time moments when the wind speed has the same value. Wind turbine speeds are determined at these times, and wind turbine outputs are estimated based on them. A method for determining wind turbine powers is described in this research, which allows viewing the operating points on the power characteristic. An examination of the performance of the control systems is performed using the provided technique. It is utilized in wind power facilities that operate at varying wind speeds. The conclusions achieved in this example were based on experimental data from the wind turbines region in Dobrogea.
