概要 |
High-resolution meso-scale meteorological model was used to simulate the detailed wind flow over the Noma Cape wind power plant in the Kagoshima prefecture, Japan. Four grids nesting method with a min...imum resolution of 50m was necessary to resolve the detailed topographical effect over the cape. Model results were statistically evaluated with the 1 minute averaged wind observation (March 1, 2003 to April 10, 2003) at the wind turbine sites. The simulated wind speed and wind direction are in a very good agreement with the observed records at wind power stations. The simulated mean wind speed agreed within the accuracy of 2% error, and simulation results for Grid 4 explained the spatial differences of wind speed within the cape. The wind acceleration effects by topography were also evaluated based on the model results during the steady wind direction period.続きを見る
