Abstract

The tower load source is derived based on the load tranfer mechanicsm of wind turbine

This paper derives the sour tower load based on the load transfer mechanism of wind turbine

and the calculation formulas for tower and nacelle loads are validated using Bladed software. It is found that the rotor loads and nacelle acceleration are the main components of the tower tilt and roll moments. The high correlation between the tower moment loads and rotor loads characteristics including nacelle displacement or tilt angle and generator power

is evaluated with Person coefficient. With the tower bottom load as research subject

the surrogate model for tower bottom load with easy-measuring parameters as input is constructed based on the multiple linear regression algorithm

and the tower bottom resultant moment load can be identified in real time. The effectiveness of model is tested by the simulated loads of large-scale wind turbine

and it is showed that the relative error of ultimate load and equivalent fatigue load between identified and simulated results is controlled within 6%. On this basis

an on-line system for tower load identification and management is proposed.
