Application And Study On Control Strategy Of Wind Turbine

With prinple of large acquisition of wind energy,this paper studies several international commonly used control strategies of wind turbine,and qualitative summarizes their respective advantages and disadvantages.To some 600kw wind turbine for the study, this paper analysis on the generating performance of different control strategies,and quantitative compare studies on the advantages and disadvantages of various control strategies.And the results applies to optimum control of coupling vibration model of wind turbine, research on collaborative simulation control of hydraulic torque converter of wind turbine, and research on maximum power tracking and performance testing of minitype aerogenerator. The main content of this paper is for optimal control of wind turbine's power. Firstly, virtual prototyping technology and neural network tool are used to forecast and analysis of wind turbine blades work in the process of dynamic response,so that the operational control accuracy leaves is improved, and the maximum wind energy is absorbed.And then,the results will be applied to the research on collaborative simulation control of hydraulic torque converter of wind turbine to achieve control strategy by the simulation software.With the study on minitype aerogenerator,this paper introduces hardware and software design research of its maximum power tracking system.This paper is structured as follows:①Chapter 1 introduces research background,and the significance of the study and the Research Status at home and abroad of wind turbine technology.②The second chapter studies on several commonly used control strategies of wind turbine, and qualitative summarizes their respective advantages and disadvantages.③Chapter 3 is for optimal control of wind turbine's power,and virtual prototyping technology and neural network tool are used to forecast and analysis of wind turbine blades work in the process of dynamic response.④In chapter4,analysis results of chapter 2 and chapter 3 are applied to whole machine system of simulating transmission of hydraulic torque converter of wind turbine,and it is made that study on collaborative simulation control of hydraulic torque converter of wind turbine by the simulation software.⑤Chapter 5 on the basis of chapter 1,2,and 3, introduces that wind turbine keeps the optimum tip-speed ratio and therefore captures maximum wind power.And with the study on minitype aerogenerator,it discusses hardware and software design research of its maximum power tracking system.
