Abstract

Wind turbines are considered one of the tallest buildings vulnerable to lightning strikes as they lack a protection system for large-scale carbon-fibre epoxy composite structures. Blades are more affected by lightning due to their large scale, which is the highest point in wind turbine structure. Knowledge of cloud-to-ground (CG) lightning, lightning protection system (LPS), electrical field relation and receptor configuration are explained. A design from an actual wind turbine blade is used to study the effect of lightning. The receptor plays an essential role in determining the efficiency of (LPS). To investigate the impact of receptors with different shapes and sizes, two different types of lightning protection receptors are used to perform their effect on lightning. Three different radius of lightning copper receptor disks, 0.1m, 0.2m and 0.4m, have been tested. A triangle with a head to the downside simulates the lightning terminal. This paper is aimed to study and analyze the most suitable lightning protection for wind turbine blades to suggest the best parameters for receptor type and size. The electromagnetic Finite Element Method simulation recommends the minimum and maximum electric field that builds up around receptors, which has been used to determine the correct size and forms of receptors. Results from the lighting strike Simulation 0.1m receptor gives the highest value of electrical field interception 56.3MV/m compared with larger size receptor 0.4m with 18.7MV/m. This research revealed the effectiveness of different types of lightning receptors and the effect of the receptor’s radius, which will offer better protection to the wind turbine.
