The mathematical model of the system of orientation of the rotor of the wind turbine by a weathervane plane
In certain criteria for the design of low-power wind
turbines should consider them on the one side as an energy
object that needs most effectively use the energy of the wind
flow, and the other side as a high risk, requiring to ensure reliable
operation of the installation during its service life.
For orientation of the rotors with plane orientation energy
losses during orientation of rotor depends on the angular speed
of orientation rotor, rotor deflection others. On the other side of
the rotor, angular velocity orientation affects the gyroscopic,
inertial and other loadings in the blade, in accordance, determines
the lifetime of the blade and wind turbine as a whole.
Today the mathematical models of the orientation systems
of the rotor in the direction of air flow, taking into account a
number of parameters and system performance orientation of the
rotor. It is necessary to take into account the continuous
improvement of designs of wind turbines rotor orientation,
which requires amending the already proven mathematical
models of wind turbines rotor orientation, and some assumptions
in making mathematical models can dramatically change the
picture of the physical process.
In this paper an improved mathematical model based
orientation rotor gyroscopic torque that occurs during orientation
of the rotor in the direction of air flow. This mathematical model
allows obtaining an equation for calculating the velocity of the
orientation of the rotor depending on the wind speeds, the angle
of deflection of the rotor from the direction of air flow and a
number of system design parameters orientation of the rotor,
which in turn allows to identify energy losses and gyroscopic
loads on structural elements of wind turbines in the process
