Research Of Efficiency For Wind Generators Optimal Selection In The Construction Of Wind Power

Wind energy is a kind of abundant reserves, clean green energy, is also a kind ofenvironmental protection and mature technology of renewable energy, has the verybig development value and use value. This article emphatically from the wind farmconstruction period, about chooseing the type of wind in the economy, in particularwind resources in the cases, selecting the wind generator to match wind power, get thebiggest value, using the energy to create the best economic effect.This paper system introduced to wind power generation principle, using weibullmodel by fitting for wind speed distribution, and the weibull parameters using statisticestimation, maximum likelihood estimation method, the least squares and averagewind speed and maximum wind speed estimation method for the estimation, the windresource observation system for wind resources for observation, and statisticalanalysis of observation data. This paper systematically evaluate for wind energyresources, introduces the wind resources evaluation of three steps: regional primaries,regional wind resources evaluation and microcosmic location, analyzed the windresources evaluation period need to pay attention to project, including the installationof wind towers measurement, measuring the wind data validation and data processing,and the problems that should be paid attention to each project.This paper introduces the basic components and the wind generator classification,and each part for WTG mathematical model of wind model, including rotor pneumaticmodel, transmission system model and the wind machine model on wind farm, theconstruction during the selection of a wind turbine, emphatically from the singlemachine and fan on the research and capacity of wind selecting type of economicanalysis. This paper choosing the type of wind turbine relative parameters includingcapacity coefficient, wind power cost, etc., analyzed the capacity coefficientcalculation method, and the premise with fan capacity coefficient, the various fanapplication in specific wind farm cost of investment, analyzes the cost of wind power,and a calculation method for the mainstream models of wind turbines at home andabroad in the specific application of investment cost calculation wind, elected for thebest wind model wind, get the maximum economic benefit.
