Abstract:Nowadays energy shortage and environmental issues have been paid attention by more and more people,renewable and clean pollution-free energy more and more get the favour of people. Wind energy is a clean renewable energy and its reserves are very rich,thus wind power technology attaches great importance to by the countries.This article mainly about a brief introduction of the background and status quo of wind power,For the ac excitation variable speed constant frequency technology research of certain depth,and established the mathematical model of ac excitation doubly-fed motor.According to the composition of wind power generation system,the wind generating set apart for wind speed,wind turbine,drive system and generator subsystem,and carries on the model of these subsystems,by using the software of MATLAB/simulink for simulation model.Finally the mainstream for variable speed wind turbine power generation system control part made some brief research suggests.
Keywords Wind power generation system Ac excitation variable speed constant frequency Doubly-fed motor Mathematical modeling The matlab simulation
