6 FAQs about [Loading and unloading of wind turbine blades]

Do wind turbines have blade load research?

A comprehensive assessment of blade load research of wind turbines is presented. The key issues and their progress involved in blade research and application are discussed. Future developments and challenges in blade load research are proposed. Load identification is the premise of wind turbine blade design and control.

Why is blade load important in wind turbine design?

The loads acting on wind turbine blades are the primary basis for the blade design of wind turbines and even the whole machine. During the turbine operation, the blade load is an essential factor leading to the failure of wind turbines. Thus, the blade load is a focus of attention in both the design and operation phases.

How to control blade load in a wind turbine?

Blade load control is usually achieved indirectly by optimizing wind turbine motion control. Three main motions affect the blade load, i.e., the rotor rotation, blade pitch, and yaw motion. A more detailed consideration involves the shaking of the tower and even the platform in the case of Offshore Floating Wind Turbines (OFWTs).

How can a wind turbine blade load be reconstructed?

Some effective countermeasures, e.g., reconstructing the historical service loads on wind turbine blades with the help of both blade load sensors and the Supervisory Control and Data Acquisition (SCADA) system, are also proposed. 1. Introduction

What is the effect of gravity load on wind turbine blades?

If large flexible deformation occurs while the blade is running, the effect of gravity load will be more complicated. Centrifugal load. The centrifugal force caused by the rotor rotation of turbines is always outward along the blade. The centrifugal load has certain benefits to wind turbine blades.

What is aerodynamic load in wind turbine?

Aerodynamic load. When the airflow flows through the blades of a wind turbine, there will be a lift and a resistance on the blades due to the special shape of the blade airfoil. This force produced by the flow of air is called aerodynamic force. On the one hand, the aerodynamic force will drive the blade rotation.
