Surge protective devices should be installed on both sides, namely in the pitch system and in the controller. The availability of wind turbines, especially that of offshore wind turbines, is gaining increased importance. Therefore, lightning current and surge arresters must be monitored for signs of pre-damage (condition monitoring).
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.
Wind power has no effect on base load. However, since base load providers can not be ramped down, if wind turbines produce power when there is no or little peak load, the extra electricity has to be dumped (e.g., into the ground) or the wind turbines turned off (”curtailment”). How does wind power affect peak load?
Due to their exposed location and height, wind turbines are vulnerable to the effects of direct lightning strikes. Several studies have shown that one must reckon with at least 10 di-rect lightning strikes to wind turbines in the multimegawatt range every year.
The rapid expansion of wind power generation has brought problems involving lightning strikes to the fore. Many such incidents have damaged not only the wind turbine that was actually struck, but also
In this paper, two lightning surges are used in the investigation. Each lightning surge is simulated as controlled current source in the form of two slope ramps. The first lightning surge is the
1. Introduction The safe, reliable operation of electrical power systems requires the ability to predict and model the sources of fault current, including contributions from wind powered
The long cable runs and frequent switching operations found in multi-tower wind farms puts the wind turbine step-up transformer at greater risk than a conventional distribution or power transformer
Wind power generation has expanded rapidly worldwide over the past 15 years. Europe''s wind farms generated 458 TWh of electricity in 2020 and total wind energy capacity exceeded 220
The standard recommends verifying the lightning current with-stand capability of these systems in high-current tests with the first stroke and the long stroke, if possible, in a common
Simulating the actual lightning strike, an edge current feature defines a 20 kA current source that targets a turbine, capturing the temporal nuances of a lightning surge. Furthermore, to

Research in this work provides a reference for the lightning protection upgrades to onshore wind power transmission systems. Backgrounds Statistics of Lightning Strike Faults
The preferred source that wind power may replace on the grid is hydro power, which is already carbon dioxide free. If a conventional source is replaced, it may simply be ramped down or switched from
