Abstract: On the basis of the micro-sitting of mountain wind farm in Yunnan Province, a technique route of rechecking for micro-sitting of mountain wind farm is proposed for optimizing power generation in this paper. Mainly based on equivalent load hours, wake losses and wind turbine spacing, some positions of wind turbines have been adjusted. At the same time, annual theoretic power generation capacity and wake losses of single turbine under different models are calculated and analyzed. The comparison results show that the annual theoretic power generation capacity with adjusted wind turbine position is increased, while the wake loss is decreased, and the economic benefit are gained significantly.
