Influence of the terminal capacitor on the performance characteristics of a self excited induction generator

The Analysis and Modelling of a Self-excited Induction Generator Driven by a Variable Speed Wind Turbine

“…One is the per-phase equivalent circuit which includes the loop-impedance method adopted by (Murthy et al, 1982) and (Malik & Al-Bahrani, 1990), and the nodal admittance method proposed by (Ouazene & Mcpherson, 1983) and (Chan, 1993). This method is suitable for studying the machine's steady-state characteristics.…”

“…Loop impedance and nodal admittance methods used for the analysis of SEIG are both based on per-phase steady-state equivalent circuit of the induction machine (Figure 4), modified for the self-excitation case. They make use of the principle of conservation of active and reactive powers, by writing loop equations (Murthy et al, 1982], (Malik & Al-Bahrani, 1990), (Al-Jabri & Alolah, 1990) or nodal equations (Ouazene & Mcpherson, 1983), (Chan, 1993), for the equivalent circuit. These methods are very effective in calculating the minimum value of capacitance needed for guaranteeing self-excitation of the induction generator.…”

A reliable and accurate calculation of excitation capacitance value for an induction generator based on interval computation technique

“…Two models are reported in [7][8][9][10][11][12] for the analysis of selfexcited induction machine. One is based on the per-phase equivalent approach and the other, the d-q axis model, is based on the generalized machine theory.…”

Novel Voltage Controller for Stand-alone Induction Generator using PWM-VSI

“…Another limitation of the SEIG in stand-alone systems is its inability to control the terminal voltage and frequency under change in load and wind speed. To overcome this problem, several methods are proposed in [2]- [4]. The capacitor excitation [3], [4] is suitable only when there is a constant load at the IG terminal and is driven at constant mechanical speed.…”

“…To overcome this problem, several methods are proposed in [2]- [4]. The capacitor excitation [3], [4] is suitable only when there is a constant load at the IG terminal and is driven at constant mechanical speed. However any change in load and rotor speed may result in a loss of excitation.…”
