Abstract :
The grounding system plays an important role in the quality of power produced by windfarms, since overvoltages caused by a fault situation, have to be successfully dispersed into the ground. In this paper the effect of grounding system design in transient overvoltages appearing in windfarm electrical installations is studied. In particular, the effect of interconnecting individual wind turbine grounding systems via horizontal strips on transferred overvoltages is examined
