This article for the purpose in here is to discuss optimization of the whole light wind turbine system design and analysis of the comparison results with physical wind turbine in Yangmingshan, Taipei (460m height) and simulate data. The technique of pseudo-measurement will be loaded and verified with the data from the real wind turbine. Other part in this article is to analyze the advantage, disadvantage and differences between the large and light wind turbine with experience. Through a series of analysis we can pick and trade-off the wind turbine under the different environment.
