Mixed Eccentricity Fault Diagnosis in Salient-pole Synchronous Generator Using Modified Winding Function Method
In this paper, winding function method (WFM), applied to a faulted synchronous generator, is modified and is used for online diagnosis of mixed eccentricity fault. For the first time, the static and mixed eccentricities are modeled in synchronous generators. A modified winding function (MWF) method introduced here is more precise compared with previous methods. This MWF enables to compute the a...
متن کاملA Review on Modelling of the Maximum Lagging Current Test Method of Salient Pole Synchronous Machines
Quadrature-axis reactance for various reasons comes into account as one of the most important parameters of salient pole synchronous machine. There are several common standard methods for measuring this parameter that also have been explained with some details in the standards, scientific papers and text books. One of these methods is the maximum lagging current test that is done simply at no-l...
متن کاملEccentricity Fault Diagnosis Studying for a Round Rotor Synchronous Machine
The paper presents a mathematical base modeling combined to Modified-Winding -Function-Approach (MWFA) for eccentricity fault detection of a round-rotor synchronous machine. For this aim, a 6-pole machine is considered, and the machine inductances are computed by MWFA in healthy and also under eccentricity fault. A numerical discrete-time method has been proposed to machine modeling in voltage-...
متن کاملTime-stepping Finite-element Analysis of Dy- Namic Eccentricity Fault in a Three-phase Salient Pole Synchronous Generator
In this paper, two-dimensional time-stepping finiteelement (TSFE) method is performed for modeling and analyzing of a salient pole synchronous generator with different degree of dynamic eccentricity (DE) fault. TSFE analysis is used to describe the influence of DE fault on the flux distribution within the generator and no-load voltage profiles at low and high field current is obtained for healt...
متن کاملcomparison of conventional salient-pole synchronous generators and permanent-magnet-assisted salient-pole synchronous generators based on finite element analysis
this paper presents a novel salient pole synchronous generator i.e. permanentmagnet-assisted salient-pole synchronous generator (pma-sgs). due to saturationof conventional synchronous generators (sgs), permanent-magnet-assisted salientpolesynchronous generators (pma-sgs) are presented. pma-sgs are a new type ofsalient-pole synchronous machines with extra permanent magnets (pms) betweenthe adjac...
