In order to plan protection measures, it is advisable to subdi-vide the wind turbine into lightning protection zones (LPZs). The lightning protection system of a wind turbine protects two sub-systems which can only be found in wind turbines, namely the rotor blades and the mechanical drive train.
The wind turbine protection scheme may include voltage and frequency relaying to protect the generator. For example, some wind turbines may trip for frequencies at or below 95 percent of nominal, or above 103 percent of nominal, with an appropriate time delay.
The IEC 61400-24 (EN 61400-24) standard, the IEC 62305 (EN 62305) standard series and the guidelines by Germanischer Lloyd (e.g. GL 2010 IV – Part 1: Guideline for the certification of wind turbines) form the basis for the protection concept.
Wind Electric Plants are composed of many wind turbine generators (WTGs) which are connected to a collector substation through a collector system. The collector system is connected to the main substation or Point of Interconnection (POI) where the voltage is stepped up to the transmission voltage level.
Lightning continues to drive significant operational risk for wind turbines if you do not have an eficient lightning protection design and system. Spoiler alert: At Polytech we develop and produce
Using a decomposition method followed by the integration of protection components, we propose a combined protection system designed to improve the overall resilience of wind turbines.
