Improvement of Wind Turbine Lightning Receptor

This project focuses on the study of lightning protection theory, knowledge and basis. Knowledge of cloud to ground lightning, lightning protection system (LPS), electric field relation, receptors configuration are elaborated. This project is aimed to study the practical parameters of LPS, including the relation between receptor size and electric field strength. Other than that, this project aimed to test three different diameters of receptors 0.2m, 0.5m and 0.8m with different needles numbers and lengths. This paper is aimed to develop a new shape of wind turbine receptors with different needles number and length also to suggest the parameters for receptor diameter and needles. Finite Element Method (FEM) has used for this research, the proper dimensions and shapes of receptors simulated by suggesting the minimum and maximum electric field that accumulates around receptors.
