Abstract:

In order to develop wind resources of Horqin sandy land, provide convenience and safety of energy for its management, the author analyzed the wind energy resources based on the data of wind direction and wind speed from weather station of Naimanqi and the wind tower of Guribanhua wind farms, where are the most typical areas of Horqin sandland. The results showed that the annual average wind speed corrected was 4.9, 6.8, 7.0, 7.2, 7.3 m/s, of which height of tower at 10, 60, 65, 70, 80 m, respectively. And the corresponding wind power density was 136.5, 315.4, 341.3, 365.6, 382.1 W/m2, respectively. The change rule of intra-annual variation between wind speed and wind power density by monthly was basically identical. Through the above data, there was more rich in wind energy resources, and had fulfilled the requirements of construction a large-scale wind power plant.
