The purpose of this paper is to describe the design of a direct-drive, permanent magnet synchronous generator to be used in the addition of electrical generation capability to water-pumping windmills. A characterization of the existing turbine structure is given in order to determine the generator's nominal mechanical input parameters. Electric machine topologies currently used in wind energy conversion...
This paper presents a combination system of wind energy conversion and hydrogen production. Hydrogen is expected as alternative energy sources in the future, and it is the best way to produce it from renewable energy like wind energy. On the other hand, the output of a wind generator, in general, fluctuates greatly due to wind speed variations, and thus the output fluctuations can have a..serious...
The development of the brushless doubly-fed induction generator (BDFIG) system and flexible power flow controller for the wind energy conversion is proposed in this paper. The system employs two cascaded induction machines to eliminate the brushes and copper rings in the traditional DFIG. The dynamic model of BDFIG with two machines' rotor electromechanically interconnected is presented and the control...
