Objectives of the variable-speed constant-frequency generating system are significantly different from those of a variable speed drive system, implementation strategy of field orientation control of induction machines must be re-examined.
A stator field orientation control method suitable for the doubly excited induction machine in. [Show full abstract] fundamental theory to be proved in this thesis is that, by applying a doubly-excited generator in a variable-speed generating system, it would be possible to electrically.
Smart Structure for Small Wind Turbine Blade. by applying a doubly-excited generator in a variable-speed generating system, it would be possible to electrically control and adjust the turbine.
Doubly-fed electric machines also slip-ring generators are electric motors or electric generators, where both the field magnet windings and armature windings are separately connected to equipment outside the machine. By feeding adjustable frequency AC power to the field windings, the magnetic field can be made to rotate, allowing variation in motor or generator speed.
Nov 20, · So, Brushless Doubly-Fed Induction Generator (BDFIG) was proposed to replace the traditional DFIG. Besides eliminating the slip rings and brushes, BDFIG has other advantages such as the improvement of reliability and cost effectiveness. This paper deals with mathematical modelling of BDFIG based Wind Electric Generator (WEG).Cited by: 4.
Discussions ranging from the technical aspects of generation, transmission, distribution, and utilization to power system components, theory, protection, and the energy control center culminate in the most modern and complete introduction to effects of deregulating electric power systems, blackouts and their causes, and minimizing their effects.
3 CHAPTER Modeling and Analysis of Induction Machines Before the development of the polyphase AC concept by Nikola Tesla  inthere was a competition between AC and DC systems.

The system can also control the active and reactive current flow of the line according to its command signal. The system to be described is composed of a flywheel driven synchronous machine together with a natural commutated cascade cycloconverter.
The doubly excited brushless reluctance machine was developed from the self- by operating the generator at variable speed, the system can track the maximum power point curve of the wind turbine and both a VSCF generating system or variable speed drive system, and a reactive powerCited by: 1.

DFIG based wind turbine. However, there are increasing applications of synchronous motors in variable frequency/ variable speed drives.
In the polyphase synchronous machine, a number of coils are distributed around the periphery of the stator and are connected in such a fashion as to form a winding of the appropriate number of phases and number of poles.
