The quality of wind farm selection directly affects the results of wind power generation. Wind energy supply is governed by many factors, including climate, topography, sea and land. Since wind energy is dispersed in the spatial distribution, it is also unstable and discontinuous in the temporal distribution. Therefore, before selecting a site, select favorable land and carry out analysis to determine whether it is possible to build a wind farm. Once determined, short-term wind measurements and observations are typically carried out for a year. We also calculate the social and economic correlations between the power grid, transportation, residents and other factors, and then ultimately determine the location of the best wind farm.
Site selection is generally divided into two stages: pre-selection and site selection.site. Pre-screening is to scan a large area of 10*104KM2, filter a more suitable medium-scale area of 1*104KM2, and then carry out inspection to select a small-scale area of 100KM2. This area can be used empirically and some noodles are available. Then collect weather data and set up several points to observe wind speed. The fixed point is to estimate the wind energy potential based on observing wind speed data, make a feasibility assessment, and finally determine the best location of the wind turbine.
Technical criteria for site selection should be based on areas with abundant wind resources, high capacity coefficients, stable wind direction, small annual changes in wind speed, less than meteorological disasters and less turbulence intensity, so as to obtainthe ideal effect.
Knowing the above, you can accurately determine the location according to the technical principles of wind farm site selection, and then analyze the terrain characteristics, make full use of the terrain with increased wind speed, then determine the installation. of the location of the wind turbine. First determine the prevailing wind direction, and the terrain classification can be divided into flat terrain and complex terrain. On flat ground, the main influence is the roughness of the ground; in complex terrain, in addition to the roughness of the ground, the characteristics of the terrain must also be taken into account.
