This paper presents the no-load practical synchronous speed characteristics of a laboratory model induction machine of 120 W capacity. Critical, minimum and maximum capacitance required for excitation are calculated from the no load curve for voltage buildup, rated voltage and current respectively; at various super synchronous speeds. A realistic model of the machine is presented on Matlab/Simu...

which a generating plant driven by renewable energy sources, such as wind energy, is connected to partially serve loads. This research demonstrates the induction generator by two forms: i) power (PQ) model and ii) admittance (Y) model. Solution convergence and model accuracy are observed in order to predict power flow distribution through feeder lines resulting from the grid connection of a ren...

Analysis of self-excited induction generator reveals that these machines are not capable to maintain the terminal voltage and frequency in the absence of expensive controllers. A simple way to control the voltage is through series compensation whereas frequency control is possible through operating speed. In this paper Genetic Algorithm has been used to model the control strategy for proper rea...

By varying effective rotor resistance of a self excited slip ring induction generator, the magnitude and frequency of the output voltage can be controlled over a wide speed range. A steady state analysis based on normalized equivalent circuit enables th...

This paper presents simple and accurate approach to compute the minimum value of capacitance required for initiating the voltage build-up in a three-phase selfexcited induction generator.
