Title The maximum wind energy tracking control of wind power
generation system
Abstract
Wind energy is widely distributed in nature ， it is clean and
pollution-free ， and huge reserves ， In today's fossil energy is
depleting,Improve the utilization of wind energy can not only alleviate
the energy crisis of humanity，But also help ease the conventional energy
development and utilization ， and environmental pollution problems
caused.This article describes how to use the tip speed ratio method to
achieve wind power generation system maximum wind energy tracking.
In this paper， by understanding the structure and principle of wind turbine，
found through control of the wind turbine blade tip speed ratio wind machine
can achieve the maximum wind power tracking， on this basis， through analysis
of several common principles of maximum power tracking algorithm，based
on the optimal tip speed ratio control simple clear easy to control，the
characteristics of this method to implement the wind power generation
system research of maximum wind power tracking Through the design of wind power
system and the simulation respectively，to achieve the maximum power tracking for
wind power generation system.
Secondly ， on the structure and principle of the permanent magnet
direct-drive type generator based on the research analysis，including wind
speed model is established，the model of wind turbine and generator model，
the mathematical model was obtained through the generator based on d - q
q axis current control to realize the speed of the fan control method，
in order to realize the wind machine always work in the best state of tip
speed ratio.
Finally experiment using Matlab/Simulink simulation，wind power system
simulation model was set up，implement best tip speed ratio control
algorithm is completed by wind power system simulation，the maximum wind
power tracking and the results are analyzed.Keywords: Wind power generation system the largest wind energy tracking the
optimum tip-speed ratio Direct-drive Permanent Magnet Synchronous Generator
