A Shadow Impact Evaluation System of Wind Power Site Utilizing Google Earth

Abstract

Shadow flicker problem on the window power site is growing even in Japan. In this study, the impacted duration and impacted time were calculated on the sun orbit model. The shadow image calculated by our simulation methods were synthesized with DEM data from Google Earth and made shadow view. On this method, the impacted shadow range was easily visualized and was uploaded onto the Google Earth. This method made it possible for the residents surrounding the window power site to share the data of wind power plant design through internet.
