| description | Lightning receptor is a device attached to a wind turbine blade that will attract and
assist lightning current flow to the ground. However, lightning does not necessarily
strike it, instead the other part of the wind turbine is still been stroked by lightning
eventually leading to catastrophe damage of the wind turbine. This research is aimed
to develop a needle-type receptor on a wind turbine blade for lightning protection
system (LPS). Other than that, this project is aimed to study the practical parameters
of lightning protection system, including the relation between receptor size and electric
field strength. The receptors were designed by three different disk diameters of 0.2 m,
0.5 m and 0.8 m. In 0.2m receptor diameter, the comparison between the numbers and
length of needles presents that 32 number of needles and 0.3m length of needles can
attract a higher electrical field than others. Each disk diameter consists of different
needles number and length. 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. The simulation study
plays an active role in understanding and designing the receptor of wind turbines for
an effective lightning protection system (LPS), but it requires a validation under actual
conditions |
