External Lightning Protection System for Wind Turbine Blades – Preliminary Aerodynamic Results
In general, there are three components making up a lightning protection system for wind turbines. These are the receptors, the down conductor and the grounding grid. Receptors and down conductors are usually found in the more recent wind turbine blades and where the down conductors are normally installed on the internal side of the blade. Consequently, the blades are vulnerable to damage and bu...
متن کاملMaterials for Wind Turbine Blades: An Overview
A short overview of composite materials for wind turbine applications is presented here. Requirements toward the wind turbine materials, loads, as well as available materials are reviewed. Apart from the traditional composites for wind turbine blades (glass fibers/epoxy matrix composites), natural composites, hybrid and nanoengineered composites are discussed. Manufacturing technologies for win...
متن کاملComposite Technologies for Large Wind Turbine Blades
As part of the U.S. Department of Energy’s Wind Partnerships for Advanced Component Technologies (WindPACT) program, Global Energy Concepts LLC (GEC) is performing a study concerning innovations in materials, processes and structural configurations for application to wind turbine blades in the multimegawatt range. The project team for this work includes experts in all areas of wind turbine blad...
متن کاملMicrocosmic Mechanism Investigation on Lightning Arc Damage of Wind Turbine Blades Based on Molecular Reaction Dynamics and Impact Current Experiment
PVC and balsa wood are usually used in the interlayer structures of wind turbine blades. In this paper, a comparative study on the lightning damage characteristics of the two materials was carried out by molecular dynamic simulations and impact current experiments. The simulations show that the glycosidic bonds in cellulose break first, which leads to a strong decrease in the degree of polymeri...
متن کاملInnovative design procedures for large-scale wind turbine blades
cost-effective, lightweight, large-scale wind turbine blades. Material costs are continuously changing, and the use of glass fibres (E-, Sand R-glass) and carbon fibre should be explored considering density/cost, specific stiffness and strength. The various fibre angles should also be used to best meet the design requirements. Rather than just a straight blade, various blade geometries should b...
