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 windturbines should consider them on the one side as an energyobject that needs most effectively use the energy of the windflow, and the other side as a high risk, requiring to ensure reliableoperation of the installation during its service life.For or...

In certain criteria for the design of low-power windturbines should consider them on the one side as an energyobject that needs most effectively use the energy of the windflow, and the other side as a high risk, requiring to ensure reliableoperation of the installation during its service life.For orientation of the rotors with plane orientation energylosses during orientation of rotor depends on the angular speedof orientation rotor, rotor deflection others. On the other side ofthe rotor, angular velocity orientation affects the gyroscopic,inertial and other loadings in the blade, in accordance, determinesthe lifetime of the blade and wind turbine as a whole.Today the mathematical models of the orientation systemsof the rotor in the direction of air flow, taking into account anumber of parameters and system performance orientation of therotor.

This mathematical modelallows obtaining an equation for calculating the velocity of theorientation of the rotor depending on the wind speeds, the angleof deflection of the rotor from the direction of air flow and anumber of system design parameters orientation of the rotor,which in turn allows to identify energy losses and gyroscopicloads on structural elements of wind turbines in the processorientation rotor. Усовершенствована математическая модель системыориентации ротора с учетом гироскопическогомомента. Получены уравнения для расчета скоростейориентирования ротора в зависимости от скоростиветра, угла отклонения ротора от направлениявоздушного потока и конструкционных параметровсистемы ориентации ротора. Удосконалено математичну модель системи орієнтації ротора з урахуванням гіроскопічного моменту.Отримано рівняннядля розрахунку швидкостей орієнтації ротора в залежності від швидкості вітру, кута відхилення ротора від напрямкуповітряного потоку та конструктивних параметрів системи орієнтації ротора.
