Protección a los aerogeneradores contra descargas atmosféricas en parques eólicos, aplicación parque eólico Villonaco

Abstract

This degree project aims to perform a technical methodology to define the external protection wind turbines against the affectation that present the lightning at wind farms. In this context is presented a detailed study on the evaluation of the frequency of direct strokes to define the electromagnetic environment of the lightning on the structure of the wind turbine based on a Level of Protection appropriated (LPL) and through the electromagnetic model "rolling spheres" is determined the Lightning Protection Zones (LPZ). With reference to the criteria of the standard IEC 61400-24, the technical methodology is developed for the protection of the wind turbine from the influence of interference conducted at the borders of the zones of lightning protection through capture systems, conduction of lightning and Earthing System (SPAT). This work ends with the presentation of a case study as an application the Villonaco Wind Park, which has been implemented the methodology exposed for protection against lightning.
