    This paper proposes the investigation on the performance between standard and high efficiency induction machines operating as grid connected induction generators having same rating of three phase, 2.2kW, 220/380V, 4-poles for supplying electric power to utility grid. Analysis and comparative study on operating of induction generators under transient and steady state conditions at no-load and full-load have been performed. Research results will be guidelines for an application of wind induction generator for electricity generation. © 2008 IEEE.

    Design, analysis, and construction of a small scale self-excited induction generator for a wind energy application

    This paper proposes the design, analysis, and construction of a three phase, 0.75 kW, 220/380 V, 3.4/2.0 A, Δ/. Y connected, 4 poles, SEIG (self-excited induction generator) based on empirical rules. The designed SEIG offers improved high efficiency and power quality. The design takes into consideration a skew effect and power quality. A 2D-FEA (2 dimension finite element analysis) is used to consider core loss, flux density and circuit parameters of the designed SEIG. The designed SEIG has been tested and compared with a standard SEIG under various operating conditions in terms of efficiency and power quality. Consideration of capacitance for the SEIG based on steady-state equivalent circuit model and a power flow diagram is also given. Research results can be guidelines and recommendations for development of small wind induction generators for effective electricity generation. © 2010 Elsevier Ltd.
