Wind resource assessment is an important link in the construction and operation of the wind farm. The icing of wind turbine blades will increase the blade load and reduce the power generation

which will affect the correct assessment of wind resources

resulting in large errors between calculated values and actual power generation. This project takes a mountain in the south as an object

studies the wind resource assessment method considering the impact of icing

carries out terrain simulation and analysis of wind field characteristics

derives microsite selection results

and makes the economic benefit analysis under the conditions of icing and non-icing. Using WindSim soft to evaluate the wind resource situation in the area

the results show that the height of the mountain range is about 570 m

the highest places appear in several areas

the trend is relatively mild

the slope is not large

and the speed component

the point values of turbulence energy

turbulence loss rate

and turbulence frequency tend to stabilize

and the residual value converges to zero

indicating that the wind flow is stable and suitable for the establishment of a wind farm. The wind energy resources are relatively good and have a certain development value.
