Abstract: The protection of the wind turbines is one of the significant problems, especially as lightning strikes the blades. In this paper, the authors bring forward a model in which nine interconnected wind turbines are connected to the infinitive bus by underground cables. When the blades are struck, for detailed investigation, all the cables inside the wind turbine and underground cables, tower, blades, and other equipment of wind turbine need to be designed in transient mode. Accordingly, the grounding system is also considered by the time-domain model, in which transient grounding resistance behavior is based upon the frequency-dependent model. For this purpose, the EMTP.rv is employed to study the transient behavior of the wind farm when the blades are struck. Eventually, by studying the residual voltage and discharged current in medium voltage surge arrester (MVSA) when lightning strikes WT, the energy absorbed by the MVSA is calculated and employed to evaluate the wind farm resilience against a different type of lightning. As a result, a new approach can be advised for the protection of wind farms against lightning by investigating the energy absorbed by MVSA.
