Reinforced Concrete Wind Turbine Towers: Damage Mode and Model Testing

Prestressed Concrete Wind Turbine Supporting System

Suppression of the vibrations of wind turbine towers

We investigate the suppression of the vibrations of a wind turbine tower using colocated feedback to achieve strong stability. We decompose the system into one model describing the vibrations in the plane of the turbine axis and another model in the plane of the turbine blades. In the plane of the turbine axis, we obtain a non-uniform Spacecraft Control Laboratory Experiment (SCOLE) model with ...

Wind Turbine Testing Control System

The main greenhouse gases (GHGs) producer is represented by the fossil burning systems. The paper presents the effect on the GHGs emission combined with the economic effects of a new pumping system method of automatic mixing of hot and cold water circulated with variable speed driving pumps and adjustable vanes. Considering the potential economic and environmental effects combined with the soci...

STRUCTURAL ANALYSIS AND STRUCTURAL OPTIMIZATION OF SELF-SUPPORTING TRUSS TOWERS TO SUPPORT A LARGE WIND TURBINE

This article aims to study the self-supporting truss towers used to support large wind turbines. The goal is to evaluate and validate numerically by finite element method the structural analysis when the lattice structures of the towers of wind turbines are subjected to static loads and these from common usage. With this, it is expected to minimize the cost of transportation and installation of...

Wind Turbine Blade Design for Subscale Testing

Two different inverse design approaches are proposed for developing wind turbine blades for sub-scale wake testing. In the first approach, dimensionless circulation is matched for full scale and sub-scale wind turbine blades for equal shed vorticity in the wake. In the second approach, the normalized normal and tangential force distributions are matched for large scale and small scale wind turb...
