New approach to determine the critical capacitance for self-excited induction generators

Excitation capacitance requirements of three phase self excited induction generator for WindMill application

“…When the R-L load is connected to self the complex form of the differential equ linkages chosen as state variables in the a frame is given [8] where subscript 's' denote is for rotor:-ω…”

“…The same author also determined the optimal size of capacitance for maximum output power of the generator in [7]. [8] have attempted the determination of the critical value of capacitance using complex impedance matrix method of SEIG. Recently [9] has determined the boundary values of excitation capacitance and minimum load impedance for wind driven SEIG.…”

Nouvelle approche pour la prédétermination des caractéristiques externes des génératrices asynchrones fonctionnant dans le cadre de l'îlotage /

“…Nombreuses sont les études qui appréhendent ce problème d'auto-amorçage de manière numérique [33], [34], [35], pour déterminer ce qui est qualifié de capacité critique d'autoamorçage. La transformation utilisée est celle de Park (transformation à deux axes).…”

Instantaneous Symmetrical Component Theory Based Voltage and Frequency Controller for Isolated Small Hydropower Generation

“…Despite all of this, commercialization of an asynchronous machine as an isolated asynchronous generator (IAG) is still a bottleneck because of its unsatisfactory voltage and frequency regulation and power quality problems, even when driven under constant power prime mover and feeding frequently varying loads [4]. As the asynchronous machine is isolated, the reactive power for its operation may be supplied by a VAR generating unit connected across its terminals, which is generally realised using the capacitor banks [5,6]. The capacitor banks are selected such that when driven at rated speed, they should produce the rated voltage at no-load operating under magnetic saturation.…”
