Lightning Attachment to Wind Turbine Blades

EasyChair Preprint no. 5259, version 2

Abstract

The lightning receptor is a device attached to the wind turbine blade which is purposely used to attract electric field from the lightning strike and assist the flow of the lightning current to the ground to protect the wind turbine blade from damage. As the objective of conducting this research, we are aimed to develop a new shape of wind turbine blade lightning receptor to maximize the probability of lightning protection to the wind turbine blade. To achieve the objective, we are required to investigate the practical parameters of the lightning protection system, including the relationship for the number of receptor needles in affecting the electric current strength accumulated around the receptor, and the relationship rotational degree of wind turbine blades in affecting the electric current strength accumulated around the receptor. Thus, the Finite Element Method (FEM) has been used for this research, with simulating a different number of receptor needles as the manipulated variable, while electric current strength accumulated around the receptor as the response variable for the project research study.

Keyphrases: Electric current strength accumulated, Finite element method., Lightning receptor
