When the large scale wind power site is built, it can't get the expected amount of power generation in many case with an influence of the wind turbine wake by the arrangement of the wind turbine. Then, the wind model which can calculate the wind which took the influence of wake into consideration in complex terrain was developed. Wake formation is modeled by the momentum theory, and included into the k-ε model, and the decrement of the velocity of the wind is found. As a result of calculating the influence of wake at Tomamae Winvilla Wind park by using this model, in the part of wake, About 10%-20% of the velocity of the wind decreased.
