Analysis of Saturated Self-Excited Dual Stator Induction Generator for Wind Energy Generation

Abstract

This paper presents the modeling of saturated dual stator induction generator (DSIG) for analysis of its transient and dynamic behavior for stand-alone operation. In the analytical model, the e®ect of common mutual leakage reactance between the two three-phase winding sets and the cross saturation have been considered. For this purpose, a detailed description of a procedure to introduce magnetic saturation in found models is presented. Paper also discusses the possibility of DSIG for supplying two individual loads by presenting the results of analytical and experimental study of transient behavior under various operating conditions. Use of such models leads to more accurate predictions in industrial drives, especially wind driven power generation systems. This is veri¯ed by experimental lab tests.

A nonlinear saturation model of synchronous machines with account cross saturation

“…A comparison between a new model, in which the effect of the cross-magnetizing phenomenon is included, and models with cross-saturation, is presented. Simulation verification of all the models for the two methods and of the inclusion of the crossmagnetizing phenomenon in the two-axis frame models is also reported (Marwa et al, 2013;Slimene et al, 2015aSlimene et al, , 2015b.…”

“…Obviously, when considering the different currents and fluxes as state space variables, the number of synchronous machines models is higher than known. Synthesis of possible models is rarely treated in the literature, except in Marwa et al (2014), Khlifi et al (2016), Levy (1986), and recently in Slimene et al (2015aSlimene et al ( , 2015b. In all cases, the subject is treated separately for synchronous machines.…”

Voltage and frequency regulation for autonomous induction generators in small wind power plant

“…Induction generators play an important role in renewable energy sources such as wind and hydraulic energy. Moreover, self-excited induction generators (SEIG) have been used to operate as wind-turbine generators in an autonomous mode (Slimene et al, 2015a;2015b;Khlifi et al, 2016).…”

Performance Limits of Three-Phase Self-Excited Induction Generator (SEIG) as a Stand Alone DER

“…Self-excited induction generators have been increasingly used in isolated power system such as wind energy and hydropower system [3][4]. The SEIG has advantages such as brushless construction (squirrel cage rotor), absence of dc power supply for excitation, absence of synchronizing equipment, reduced size, good over-speed capability, reduced maintenance cost, inherent short-circuit protection capability and better transient performance.…”
