APPROXIMATION OF AEROMECHANICAL CHARACTERISTICS OF THE WIND TURBINE OF A WIND PUMP INSTALLATION IN THE LOAD OPERATION MODES BY THE METHOD OF CHANGING THE VARIABLES

Keywords: wind turbine, aeromechanical characteristic, approximation, power, moment

Abstract

The purpose of the work was to develop a method for approximating the aggregate aeromechanical characteristics of the wind turbine at discrete values of the angle of rotation to a continuous surface at tip speed ratio wind turbaine.

The approximation method consists of three stages. The first stage is to replace the variables on both coordinates and represent the aeromechanical characteristics of the new coordinate system. At the second stage, the determination of the equation of communication between the variables for two coordinate systems is carried out. In the third stage, the ordinates of the continuous surface of the aeromechanical characteristics for arbitrary values of the angle of rotation and tip speed ratio wind turbine are calculated.

The developed method is used to determine the law of regulation the angle of rotatation the blades of the wind turbine in the operating range of wind speed change.
