In order to maximize the power generated by wind turbines, we must examine the wind characteristics at the site before constructing a wind park. In such a case, so far we have estimated the expected wind energy obtained at scheduled siting points of wind turbines by using a small number of anemometers installed in a wind park. However, in Japan, a site proposed for a wind park is often in a mountainous and rough complex terrain, and hence, it is difficult to accurately estimate wind resources of all other scheduled siting points with such a small number of anemometers. To cope with this difficulty, a wind tunnel test is usually used. However, in such a complex terrain, it is very difficult to accurately estimate the wind energy production by a wind tunnel test. On the other hand, the WASP code, which was developed by Riso National Laboratory in Denmark, is well known as a good method of estimating wind energy production, but it has not been used in such a complex terrain as that found in Japan. In this work, we applied a wind tunnel test and the WASP code to Tappi Wind Park, and compared the simulation results with actually generated power. As a result, we conclude that the wind tunnel test and the WASP code are useful under the certain condition, but the accuracy of estimation is decreased in a rough complex terrain.
