THE RESEARCH OF BRUSHLESS DOUBLY-FED
WIND POWER GENERATION CONTROL SYSTEM
ABSTRACT
Now, energy sources consume increasing daily and environment empoison being serious
gradually, in the exploitation for the renewable energy source, wind power is paid great attention
by more and more countries because of its stand out excellence, The wind power generation
technology also e research hotspot of many country's scholar. And the variable-speed
constant-frequency (vscf) generation technology is paid attention more and more for its high
efficiency and practicability.
The Brushless Doubly-Fed Machine (BDFM), with simple structure and favorable
reliability, has gained renewed attention in variable-speed constant-frequency generator
applications in recent years for it features adjustable power factor and high efficiency
In this paper, based on the traditional wind power generation, the variable-speed
constant-frequency generation technology is mainly research, prehensive research on the
BDFM with cage rotor used in the variable-speed constant-frequency wind power generation.
The following items are included:
1. Summarize the research status of the wind power generation, introduce the history and
developing future of BDFM.
2. The prototype of BDFM an
