WebThe payback was also attractive since, in some cases, the payback time was less than four years. The distance between the park to be repowered and the neighboring wind farm can be a barrier since, in most cases, replacing the wind turbine with greater power and with a higher cube height increased the wake effect caused to the neighbor wind farm. WebThe DTU Wind Energy Wind Atlas and Analysis and Application Program (WAsP) has for a long time used the Park wake model – hereafter referred to as Park1 - to calculate wake effects within wind farms. Park1, originally a stand-alone program (Katic et …
