This paper presents the application of radial basis neural networks to the development of a novel method for the condition monitoring and fault diagnosis of synchronous generators. In the proposed scheme, flux linkage analysis is used to reach a decision. Probabilistic neural network (PNN) and discrete wavelet transform (DWT) are used in design of fault diagnosis system. PNN as main part of thi...

This paper presents a new rotor flux estimation method for sensorless vector controlled squirrel-cage induction generators used in wind power applications. The proposed method is based on a phase-locked loop (PLL) and the orthogonality between the rotor flux space vector and its back electromotive force (EMF) space vector. Rotor flux is estimated using stator voltage equations without integrati...

The aim of this paper is to propose different methods of control for a Doubly-Fed Induction Generator (DFIG) used in wind energy conversion systems. This paper presents a comparative study on the performance of three control methods for DFIG wind turbine. The study focuses on the regulation of the active and reactive power exchanged between the generator and the grid by the generator inverter u...

We evaluate typical performance of irregular low-density generator-matrix (LDGM) codes, which is defined by sparse matrices with arbitrary irregular bit degree distribution and arbitrary check degree distribution, for lossy compression. We apply the replica method under one-step replica symmetry breaking (1RSB) ansatz to this problem. Typical performance of irregular LDGM codes for lossy compre...

Flux-switching permanent magnet (FSPM) machines have attracted significant research attention in the field of wind power generation. In this study, utilization a magnetic flux barrier to improve performance nine-phase FSPM generator designed for low-speed applications is conducted. The proposed approach involves introducing barriers different topologies conventional and analyzing their using 2D...

Explosive-driven magnetic-flux-compression generators have been around since the early 1950s, when they were independently invented in the United States and the Former Soviet Union. Interest in these generators has been cyclic over the years and we appear to be in the upswing of renewed interest, not only in the US and Russia but other countries as well. Therefore, it was decided that it was ti...

A detailed model of wind power station, including Double Fed Induction Generator, DFIG is presented in this paper. Two control mechanisms are included in the model. The inner control system uses stator flux oriented control for the rotor side converter and grid voltage vector control for the grid side converter. The outer control system is used for wind turbine pitch angle. PSCAD/EMTDC is us...
