6 FAQs about [Lightning protection methods for wind turbine generators]

How to protect wind turbine blades from lightning?

Lightning protection of wind turbine blades 6.1. Capture of lightning by an isolated lightning tower This protection method is to construct an isolated tower, which is a little apart from a windmill and blocks lightning discharge from it.

What are lightning protection levels for wind turbines?

3.2. Lightning Protection in General Lightning protection systems for wind turbines are based on International Electrotechnical Commission (IEC) IEC 61400-24. According to this standard, the lightning protection levels (LPLs) have been set in accordance with the probability of minimum and maximum expected lightning currents, I to IV.

Why is lightning protection important for wind turbine generators?

Introduction The capacity of wind turbine generators has been increasing and the most popular one is 1000–2000 kW. Lightning protection for these large wind turbine generators is more important than that for small size. The damages of blades ( Fig. 1) need much expense because of transportation of a large blade and replacement of it.

Can a hybrid conductor protect wind turbine blades from lightning?

Two models were developed: one with a conventional type down conductor system and the other with a hybrid conductor system. The recorded findings have been compared and discussed, where it was found that the hybrid conductor system may provide alternative protection from lightning for wind turbine blades. 1. Introduction

Do wind turbine blades need Lightning receptors?

Lightning discharges may penetrate into the cavity of a blade without lightning receptors, resulting in serious damages, such as an destruction and falling of a blade. Although lightning receptors are totally useful for lightning protection of wind turbine blades, they are not perfect.

Can lightning damage wind turbine blades?

... The probability of being damaged increases with their height, and despite the existing lightning protection systems available for wind turbine blades, there are still many cases reported wherein damage is caused by lightning strikes.
