Experts theorized that a Brushless Wound-rotor [Synchronous] Doubly-fed Electric Machine System (BWRSDF), which can symmetrically motor or generate with variable speed, provides higher efficiency, higher power density, higher torque density, and lower cost than any other electric machine system, including the permanent magnet electric machine system, but only with the discovery of a practical b...

This paper presents a new approach for determining the effective control signals for damping of oscillations by performance comparison of Unified Power Flow Controller in coordination with Power Oscillation Damping Controller and Power System Stabilizer. For the analysis Modified Phllips-Heffron Model of Single Machine Infinite Bus system is established with Unified Power Flow Controller. Impac...

Doubly fed wound rotor induction machine with vector control is very attractive to the high performance, variable speed drive and generating applications[ 1-31. In variable speed drive application, the so-called slip power recovering scheme is a common practice where the power due to the rotor slip belowlabove synchronous speed is recovered to/supplied from the power source, resulting a high ef...
