“…From a system perspective, this current needs to be rectified into direct current (DC) before the plant is connected to the grid. [14,17] There are different options for the electrical interconnection of an array of linear energy converters. Most of these deal with rectification and parallel connection on the DC-side.…”

“…A linear generator enables a less complicated power take off (PTO) for wave energy conversion, since the translatory wave motion can be directly converted into electric energy. Over the last years, there have been an increasing number of reports on linear generators [1,4,[13][14][15][16][17][18][19][20]. Two of the generators have been designed for existing power plants [1,4], while the remaining references describe the linear generator as a part of a novel wave energy converter design [13][14][15][16][17][18][19][20].…”

“…Karin Thorburn, et al, (2006) offered Time-stepping FEA pertaining to variable speed synchronous generator along with a rectifier. This model keeps up the speeds of the bi-directional alternator speeds, since the application is a linear generator with respect to the ocean wave energy conversion [176]. The predominant objective of the wind power generation systems is to excerpt the maximum amount of wind energy and its conversion of electric energy.…”

Abstract:The Wind Energy Conversion System (WECS) plays an inevitable role across the world. In particular, the attention for Permanent Magnet Synchronous Generators (PMSGs) connected with wind farm is popular. This paper deals with the literature review that describes the recent advances, progresses and innovatory trends on PMSGs for WECS. Comparison between geared and direct-driven conversion systems and the classification of electrical machines used in WECS are discussed. A detailed analysis on the design aspects considering various topologies of PMSGs are encompassed in the literature. The PMSG design and optimization problems are solved by field computation techniques and optimized by using Soft Computing (SC) techniques .The threedimensional, finite element software platform for the analysis and design of PMSGs is discussed. This paper also deals with the interdisciplinary modeling, analysis, and optimization of PMSG using Finite Element Analysis (FEM) and SC techniques. Finally, PMSGs are reviewed and compared for further exploration.

The output voltage from a direct‐driven permanent magnet linear generator installed in a wave power plant varies both in amplitude and frequency. Electrical conversion is therefore necessary before grid connection can be achieved. The aim of this paper is to present an electrical conversion system based on the electric resonance phenomena. As one of the first steps in the development, and to gain further knowledge and understanding of the proposed resonance circuit, experimental tests with a single‐phase permanent magnet linear generator connected to a resonance circuit were performed. The experimental results presented in this paper indicated that a successful resonance between the generator and external circuit was achieved. The research regarding the wave energy converters lies within The Lysekil Wave Power Project at Uppsala University and has been ongoing since 2002. This article is categorized under: Wind Power > Science and Materials Energy Infrastructure > Systems and Infrastructure
