This paper presents a new topology proposal for wind turbine using an electromagnetic frequency regulator -EFR. One of the most important aspects in the wind energy conversion into the power system is the speed control, using for this purpose, in some topologies, mechanical gearboxes. These boxes often represent sources of noise and defects; they also have a short service life. The EFR presents itself as a new technology for wind turbines, to replace the traditional transmission box, being composed by an adapted induction machine, where the stator of the machine, as we know it, becomes mobile, supportive/connected to the turbine shaft. The aim of this article is to validate, through simulation, the efficiency of the proposed system. The simulations have shown positive results, validating the proposal.Keywords-Wind turbine, induction machine, electromagnetic frequency regulator, speed control. I. INTRODUÇÃODEMANDA por energia elétrica aumenta cada vez mais, contribuindo para o aumento do impacto ambiental. É necessário investir em fontes de energia renováveis. Dentre essas fontes, a energia eólica vem tomando grande destaque, promovendo a busca constante pelo aprimoramento das tecnologias envolvidas nas topologias de aerogeradores, principalmente no quesito de se trabalhar com a velocidade variável dos ventos, buscando um maior rendimento do sistema [1].De acordo com o atual estado da técnica, são utilizados aerogeradores ditos de "velocidade variável" ou de "velocidade constante". Os primeiros dependem de sistemas de conversão eletroeletrônicos, para acoplar o aerogerador à rede elétrica, o que causa limitações operacionais quando injetada a energia produzida na rede, em virtude das oscilações de tensões e da qualidade da energia produzida. Além disso, operam de forma dependente das tensões da rede elétrica, sendo desconectados quando esta deixa de operar em função de alguma avaria [2]. Como exemplo desses tipos de aerogeradores há os que utilizam geradores de indução duplamente excitados (DFIG) e os geradores síncronos multipolos.
This paper describes the implementation of a strategy to obtain the currents reference of a shunt filter active using the method of the Theory of Generalized Instantaneous Power applied to the control of a generator Induction of feeding a nonlinear load. The objectives are to establish control of generator excitation and reduce harmonic distortion caused by nonlinear load. It is made a comparison with other method for obtaining the reference currents, the dq synchronous reference. First, they are simulations using the Borland C++. The control and communications necessary for the supervisory stage were implemented via DSP -TMS320F2812.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
