Abstract: Micrositting is the key link of wind power generation technology, and it relates to the operation benefit of wind farm directly. Under the condition of complex terrain, the investment for road and power transmission line will be larger; it must be considered to get optimal comprehensive indicators, such as the electricity generating capacity, the investment benefit and etc. In current micro sitting softwares, the principle of wind turbine location is to get maximum electricity generation only. However, some other influencing factors, such as the turbulence intensity, the inflow angle, the comprehensive cost and the economic benefit, must be considered. Taking the micro sitting scheme of a wind farm in complex terrain as example, the fast investment estimation and costbenefit model was established. By using the model, sevoral schemes were compared and analyzed, and an optimal scheme was determined finally. By this example, the practical applicability of the model was verified.
