Characteristics of a doubly-fed asynchronous generator applied in wind turbines
TLDR
A mathematical model of a doubly-fed asynchronous generator is defended in the paper, using spatial vector theory, in relation to the reference axis associated with the stator.Abstract:
A mathematical model of a doubly-fed asynchronous generator is defend in the paper, using spatial vector theory, in relation to the reference axis associated with the stator. Expressions for characteristic quantities are derived, and operational characteristics for the torque, active and reactive power, power factor, and efficiency are plotted, from which generator operation is analysed at different rotational speeds. Based on this, possibilities and advantages of using doubly-fed asynchronous generators in wind turbines, for obtaining electrical energy from wind energy, are deduced.read more
