A Study Of Wind Resource Assessment Based On The WAsP Software And Wind Turbines Layout Optimization Of Wind Farm On Complex Mountain Region

Wind energy resource is a kind of clean and renewable energy, and it plays an important role in developing the wind resource and keeping social and economic sustainable development. Before developing the wind energy, the total reserves of wind resources is needed to be estimated in a scientific way; then, according to the wind conditions analysis and the estimation of the total reserves, the potential of wind energy is evaluated. The conditions analysis and the evaluation of wind resources are the foundation of the turbines layout, and have an important significance for driving wind resource development and utilization.A wind farm in complex mountain region was investigated; Based on the data of wind farm and the limitation of the estimation’s software applicated for a wind farm in complex mountain region; Paper puts forward a method that the measured data was used to make a correction for applying the forecast model, aiming to improve the application’s effect of the forecast model by entering the corrected wind data in complex mountainous region; And the improved particle swarm optimization algorithm was adopted to investigate the turbines layout. The main work and achievements are as follows.1). Using the full wind data in complex mountain areas, the wind characteristics of complex mountain region was investigated by statistical analysis and calculation of the wind parameters; And the parameters of the Weibull distribution was estimated by using different statistical algorithm. Due to the limitation of the WAsP software applicated in complex mountainous area; Paper corrected the result based on the WAsP model processing.2). To investigate the WAsP application mode in complex mountain area, the wind parameters for the wind data was setted for the correction of estimation model of WAsP. The feasibility and the credibility of the corrected data were verified and the validity of the WAsP improvement model was done.3). Based on WAsP improved model and high resolution tepographic map by SRTM terrain, the wind resource of the wind farm in complex mountainous area was evaluated, and the assessment result showed that the wind farm in the complex mountain area is value.4). Using the improved model of WAsP software, the selection of the wind turbine’s type for49.5MW wind farm and fan arrangement were investigated and the capacity was calculated. The mode of the Vestas V100/1.8MW was chosen, the theory of generating capacity was129GWh and the capacity after reduction of wake was114GWH. The improved particle swarm optimization algorithm was optimized; and the results showed that the theory of the wind power generation was improved. The paper presents an improved application mode and provides a more accurate assessment of the application model for the wind resource assessment on complex Mountain region.
