This paper presents the equivalent circuit and steady state behaviour of a recently introduced single phase generator configuration of a three phase squirrel cage induction machine. One winding of the three phase machine is used for real and reactive power control of the machine while remaining two windings are connected in series to form the output terminals to which the variable consumer load and a fixed excitation capacitor are connected. Starting from abc reference frame model, the paper derives dynamic equations of the system in both α-β and d-q reference frames. Complete set of steady state equations are then derived in α-β reference frame model before proposing a novel steady state equivalent circuit. The steady state behaviour of the machine is analysed using Matlab Simulink under different conditions of load, rotor speed, excitation capacitance and voltage applied to the controlled winding. Comparison of the steady state values obtained from transient model and respective results obtained from the equivalent circuit shows the accuracy of the derived steady state model.
A solar photovoltaic plant model has been developed for the comparison of annual energy output of different plants. The solar plant model has been designed to only require climate data commonly available in rural Australia and includes consideration of nonlinear efficiencies within solar photovoltaic systems. The comparative annual energy output of different photovoltaic technologies was identified and the effects of nonlinear efficiencies were examined.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
