Research On The Influence Of Wind Data Accuracy Of Wind Tower On Wind Farm Capacity

With the rapid development of renewable energy,the utilization ratio of wind resources is also increasing,and the application of the wind tower has been attached importance in wind farm.From the pre planning of the wind farm to the later stage that it put into use,the accuracy of wind data is the direct factor that affects the wind farm capacity evaluation.Therefore,improving the accuracy of wind measurement data is the primary task of the wind tower.Wind tower is involved in wind resource assessment,micro location,fan selection and so on.As the first equipment of wind energy resources,wind tower affect the capacity evaluation of wind farm directly.Therefore,the study of wind tower has important practical significance to the construction of the wind farm.A quantitative analysis method to study the impact of different time scales wind data on wind farm output power is proposed.The wind data in 3 time scales(30min,1h,2h)are evaluated respectively,the generation error of different time scales are compared,based on the quantitative analysis of error range of wind data under different time scales,the best time scale is obtained under different precision requirements.The research can give instructive guidance on the selection of wind data time scales when the wind data of the wind farm location area is incomplete.A quantitative analysis method to study the impact of different numbers of wind towers on wind farm output power is proposed.Three schemes are selected according to the number of different wind towers,and the error of power generation under different numbers of wind towers is compared.Through the quantitative analysis of the corresponding error range,the scheme of the numbers of the wind tower is obtained under different precision requirements.The research can give instructive guidance on wind tower location in complex terrain or high precision wind farm.
