    This paper presents analysis and investigation of the skew effect on behavior and performance of a three-phase, 220/380V, 8.7/5.0A, ?/Y connected, 4 poles, 2.2kW self-excited induction generator (SEIG) with different angles rotor skewing. A 2D finite element analysis (2D-FEA) is used to consider core loss, flux density and circuit parameters. Analysis of excitation capacitor values for the SEIG based on a steady-state equivalent circuit model including rotor skew effect is given. Skewed rotor slots with angle of 0° (non-skew), 5° and 10° for the SEIGs are employed. Testing and performance comparisons under steady-state operation with a pure resistive load have been conducted. Obtained results can be guidelines and recommendations for development of effective wind induction generators. © 2011 The Institute of Electrical Engineers of Japan.

    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.
