Steady State Analysis Of Wind Driven Sm-Bdfig In The Super-Synchronous Range Of Operation, Mahmoud A. Saleh, Maged N. F. Nashed,, Mona N. Eskander

Innovative Research Publications IRP India

In this paper a simplified mathematical model of a single machine brushless double fed induction generator (SM-BDFIG) connected to a variable speed wind turbine is presented. The SM-BDFIG consists of a slip ring induction machine, which is the main generator, a converter, and a battery pack mounted on the same shaft. In the supersynchronous speed range of operation, which is investigated in this research paper, the rotor voltage is rectified and used to charge the batteries. The steady state performance of the proposed generator is studied at different values of battery open circuit voltage, different values of the battery internal …

Dynamic Performance Of A Single Machine Brushless Dfig During Wind Speed Variation, Mona N. Eskander, Mahmoud A. Saleh, Maged N. F. Nashed

Innovative Research Publications IRP India

In this paper, the dynamic performance of the specially-designed Single Machine Brushless Doubly-Fed Induction Generator "SM-BDFIG" coupled to variable speed wind turbine is investigated. The rotor voltage of the SM-BDFIG during super-synchronous operation is used to charge a number of batteries, connected to the rotor via a 3- phase bridge rectifier. The number of charged battery cells are changed, by parallel and series connections, according to the wind speed variation, and consequently, the rotor voltage variation. The response of the stator, rotor, and DC link voltages and currents due to wind speed variations is presented. The electromagnetic torque, the stator …
