“…In the switched reluctance generator (SRG), the AC voltage generated can be used to power a load connected in parallel with the capacitor [16]. The voltage waveform contains harmonics that prevent it from being used as an alternative generator to the power grid, unless the load accepts a lower quality level, but can be used to charge a battery bank in isolated sites.…”

Abstract:Wind generation systems require mechanisms that allow optimal adaptation of the generator to varying wind speed and to extract maximum energy from the wind. Robust and affordable high-performance methods are also needed for isolated sites. This paper takes this approach, in which an AC switched reluctance generator is used as a generator with a variable rotor speed. Although the voltage obtained is of insufficient quality to connect the generator directly to the power grid, this kind of generator can be used in isolated sites to charge a battery bank with a simple bridge rectifier. Due to the nonlinear behavior of the machine with the position and current, along with the alternating nature of the current that circulates through its phases, the machine experiences cyclical energy transformations of a mechanical, electrical and magnetic nature. This paper analyzes these transformations for the purpose of providing guidelines for machine design and optimization as a wind turbine in isolated sites.

“…To describe this behavior, a plot of the flux linkage per phase with respect to the phase current is used. As a result, the transformed mechanical energy is represented by the area in a closed flux-current path [15][16][17].…”

“…As MRV têm sido tema de estudos na área de veículos elétricos e geração eólica, principalmente devido à ausência de elementos magnéticos permanentes e presença de bobinas apenas no estator [1], [2]. Logo, são máquinas que possuem um rotor mais leve que, somada a sua natureza intrinsicamente comutada, as tornam compatíveis e atrativas para aplicações em geração eólica [3], bem como em veículos elétricos.…”

Resumo -Esse artigo tem como objetivos principais: apresentar uma proposta de metodologia para o projeto eletromagnético de geradores a relutância variável de fluxo axial com núcleo do tipo C; e o seu acionamento em operação auto excitada. Além disso, não foi encontrada na literatura pesquisas sobre a utilização do gerador de relutância axial com núcleo do tipo C em operação auto excitada. Logo, o artigo possui também um caráter tutorial e aborda esse tema pouco difundido no âmbito científico nacional e internacional, auxiliando no desenvolvimento de novas pesquisas. É realizada uma análise estática do gerador, bem como estudos do comportamento dinâmico do sistema de acionamento por meio de simulações. A análise estática do gerador foi realizada com o auxílio do método dos elementos finitos em três dimensões. Já o estudo dinâmico do sistema foi realizado no Matlab/Simulink, utilizando um modelo do gerador desenvolvido a partir das curvas de magnetização. Com base na análise das respostas dinâmicas, os resultados das simulações indicam que a metodologia utilizada foi adequada para a determinação das dimensões finais do núcleo dos geradores de relutância axial com núcleo do tipo C. Palavras-Chave AXIAL C-CORE SWITCHED RELUCTANCE GENERATORS: DESIGN AND DRIVE SYSTEMAbstract -This paper aims to present a proposal of the electromagnetic design methodology of the Axial Switched Reluctance Generators with C core (C-SRG) and its drive system in self-exciting operation. In addition, it was found no research in the literature addressing the use of the self-excited C-SRG. Thus, this paper has a tutorial feature, addressing this poorly investigated subject and assisting in the development of new researches. A static analysis of the generator is also carried out, as well as studies on the dynamic behavior of the drive system using computational simulations. The three-dimensional finite element method was used in the static analysis of the generator.1 The study of the dynamic behavior of the drive system of the generator was carried out using the model developed in the Matlab/Simulink based on the magnetization curves of the C-SRG. From the dynamic results of the generators, it is concluded that the methodology applied is suitable to obtain the final dimensions of the C-SRG core.Keywords -Axial Flux, Electromagnetic Machine Design, Finite Element Method, Switched Reluctance Generator.

“…In addition, each phase is independent of each other in terms of structure and electromagnetism.

-Fast and accurate fault diagnosis of the position sensor is of great significance to ensure the reliability as well as sensor fault tolerant operation of the Switched Reluctance Wind Generator (SRWG). This paper presents a fault diagnostic scheme for a SRWG based on the residual between the estimated rotor position and the actual output of the position sensor. Extreme Learning Machine (ELM), which could build a nonlinear mapping among flux linkage, current and rotor position, is utilized to design an assembled estimator for the rotor position detection. The data for building the ELM based assembled position estimator is derived from the magnetization curves which are obtained from Finite Element Analysis (FEA) of an SRWG with the structure of 8 stator poles and 6 rotor poles. The effectiveness and accuracy of the proposed fault diagnosis method are verified by simulation at various operating conditions. The results provide a feasible theoretical and technical basis for the effective condition monitoring and predictive maintenance of SRWG.
