Evaluation And Access System Scheme For Wind Energy Resources Assessment And Access System Scheme

Wind power grid scheme is reasonable in addition to the wind farm equipment type selection and the grid given capacity to meet the requirements,area of wind energy resource is good or bad is smoothly premise,in this paper,the wind power wind energy resources assessment in detail,where the project is located,the merchant wind farm grid scheme,the selected fan model and unit interior decorating made a comprehensive study carefully,the main work includes:The accuracy of wind resource assessment has a direct impact on the important evaluation criteria for the feasibility of wind power grid connection projects,and the selection and layout of wind power units have a direct impact on the benefits of active power in wind farms,and thus have an important impact on the output of wind farms.Combining with the actual,using wind energy resource assessment professional software(WAsP)the site area of wind energy resources is analyzed,based on the site measured wind speed and direction data correction,as well as the research site area represents the years wind resources characteristic values of application of the wind farm to evaluate the wind resources is the general method and process,this paper mainly from two aspects of the wind resource assessment and wind resources characteristics launched research.Select an appropriate scheme for the access system of Dawa wind farm and verify its rationality.After the introduction of Panjin power grid and regional power consumption,the regional power grid load is predicted,and the power balance analysis is carried out based on the regional power supply planning.Several wind power grid-connection schemes are put forward according to the integrated conditions of the connected power grid voltage grade,planning capacity and regional power grid structure,etc.,and the optimal wind power connection scheme for dawa is finally obtained by comparing various indexes such as power flow calculation,short-circuit calculation and economic analysis.Select the appropriate type and capacity of the fan,and arrange the units in the field according to the situation of wind resources.The model selection should be suitable for the wind resource characteristics of the site,which is conducive to improving the power generation efficiency of the wind farm.In consideration of safety level,unit structure type,unit powerregulation mode and other factors,combined with the site strong wind day probability,high wind power density advantages,choose variable speed variable blade wind turbine.Then,according to the relationship between the typical model layout and the wind power density,therelationship between the single-machine capacity scheme and the power generation economy,and so on,it is verified that the selected model and the layout can maximize the utilization of local wind energy resources,and the economy is the best.This paper has 18 figures,19 tables and 52 references.
