Abstract :
Wind power plants are now being paid more and more attention from the environmental point of view. They are sometimes built remote from other power plants, which implies that the fault current distribution becomes different from before. Although induction generators, which still cover major part of wind power plants, do not have independent back voltage, they behave as transient sources of fault current during the critical time range. From this point of view fault analysis considering the contribution of wind farm is an important issue. Recently many wind power plants take form of wind farms, groups of many wind power sources, which compensates non-deterministic random variation inherent in wind fluctuation. But most of the research works done in the field of electrical characteristics of wind power plants do not consider this effect. This paper studies short circuit current fed from induction generators taking into account the random fluctuation of wind and its compensation by grouping them
