This paper presents a subharmonic-based brushless wound rotor synchronous machine (BL-WRSM) topology with permanent magnet-assisted (PMA) and consequent-pole (CP) structures to achieve better torque characteristics as compared the conventional WRSM. The proposed topologies use high-efficient subharmonic field excitation technique operation lower volume of magnet (PM) average, starting, maximum,...

This paper presents a nonlinear magnetic equivalent circuit method and an electromagnetic characteristic analysis verification of wound rotor synchronous generator (WRSG). The reluctance generated by the stator, rotor, air gap is subdivided to form construction. A (MEC) for WRSG constructed solved iteration method. Moreover, calculate inductance generator, d−qaxis constructed, obtained using in...

Methodology for Designing a Fuzzy Resolver for a Radial Distribution System Fault Locator. (December 2005) Jun Li, B.Eng.; M.Eng., Xi’an Jiaotong University Chair of Advisory Committee: Dr. Karen L. Butler-Purry Dr. B. Don Russell The Power System Automation Lab at Texas A&M University developed a fault location scheme that can be used for radial distribution systems. When a fault occurs, the s...

In this paper, a sliding mode controller for the stator voltage amplitude of a stand-alone wound rotor synchronous generator is presented. The standard dq-model of the electrical machine connected to an isolated inductive load is obtained. Then, the control law is designed using sliding mode techniques. The controller introduces a dynamic extension so that the stator voltage amplitude has relat...

This paper presents a topology for the brushless operation of wound-rotor synchronous machine based on subharmonic excitation technique by using two sets multi-pole windings armature as well rotor. The consist four-pole three-phase main winding and two-pole single-phase additional winding, responsible generation fundamental components magnetomotive force (MMF), respectively. rotor contains fiel...

MOTIVATION Gene expression profiling has become an invaluable tool in functional genomics. A wide variety of statistical methods have been employed to analyze the data generated in experiments using Affymetrix GeneChip microarrays. It is important to understand the relative performance of these methods in terms of accuracy in detecting and quantifying relative gene expression levels and changes...
