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

Engineering and Technology JournalNatural Lightning strikes are the main cause of over voltages in the power system. Such lightning over voltages can damage the system insulation if sufficient protections are not provided to the system. In the power system ground wire or shield wires are placed on top of the transmission line tower for the protection of transmission lines against ...
