Evaluating the High Frequency Behavior of the Modified Grounding Scheme in Wind Farms
Applied Sciences, 2017 Wind generators are exposed to numerous destructive forces such as lightning and are therefore vulnerable to these phenomena. To evaluate the transient behavior of a wind power plant during direct and indirect strikes, modeling of all relevant components
