“…The main drawback of self-excited induction generators is their inherent poor voltage regulation capability, which is the limiting factor for their wide use [18]. Relevant research has been done on the voltage and frequency control of self-excited induction generators and some achievements have been obtained [19][20][21][22].…”

In this paper, the Routh criterion has been used to analyze the stability of a self-excited induction generator-based isolated system which is regarded as an autonomous system. Special focus has been given to the load capacity of the self-excited induction generator. The state matrix of self-excited induction generators with resistor-inductor load has been established based on transient equivalent circuits in the stator stationary reference-frame. The recursive Routh table of self-excited induction generators is established by the characteristic polynomial coefficients of the state matrix. According to the Routh stability criterion, the necessary and sufficient condition to predict the critical loads of self-excited induction generators is deduced, from which the critical load impedance can be calculated. A simple self-excited induction generator-based isolated power system has been built up with a 2.2 kW self-excited induction generator. The theoretical analysis and experiments were all carried out based on this platform. In the range determined by the minimum excitation capacitance (C min ) and the maximum excitation capacitance (C max ), the critical loads under various power factors have been calculated. The agreement of the calculated theoretical results and experimental results demonstrate the effectiveness and accuracy of the proposed analysis method. The conclusions achieved lay a foundation for further application of Routh stability criterion in self-excited induction generator-based power systems analysis.

“…Many configurations are available in the literature for obtaining a DC voltage of constant magnitude or AC voltage of desired magnitude and frequency [4][5][6]. Further, to balance the mechanical input and the electrical output power from the wind energy systems, many power electronic interfaces and control techniques have also been proposed [7,8].…”

In this study, voltage oriented decoupled current mode control technique has been proposed for the operation of the capacitor-excited induction generator with pulse-width modulation (PWM) rectifier systems for supplying isolated DC loads. The proposed controller maintains constant voltage at the DC load terminals and also maintains unity power factor with very less harmonics at the PWM rectifier input terminals. The configuration and implementation of the control scheme employing dSPACE 1103 real-time controller have been fully described. A method for predetermining the steady-state performance of the proposed system has been developed and described with relevant analytical expressions. The effective load at the generator terminals becomes only resistance, since unity power factor is maintained at the PWM rectifier input terminals by the closed-loop controller. To verify the successful working of the proposed control strategy during transient conditions, the proposed system has been modelled in the MATLAB/ Simulink toolbox and results are presented. A prototype system consisting of CEIG, PWM rectifier and the associated control circuits has been built in the laboratory for experimental verification. A close agreement between the experimental results and predicted values confirms the validity of the analysis and successful working of the proposed control strategy.
