博士 === 國立成功大學 === 電機工程學系 === 89 === This dissertation presents dynamic and steady state performance of an isolated self-excited reluctance generator (SERG) under three-phase balanced and unbalanced loading conditions. A d-q axis equivalent-circuit model is employed to derive dynamic equations under balanced loading conditions. An approach based on three-phase reluctance machine model is employed to derive dynamic equations under unbalanced loading conditions. This dissertation presents on approach based on eigenvalue and eigenvalue sensitivity methods to determine critical excitation capacitance and minimum loading resistance. When balanced loading conditions, performance analyses of the studied SERG under different power-factor loads are investigated. When unbalanced loading conditions, transient responses of the studied SERG subject to sudden disconnection of excitation capacitor and loading resistance are clearly investigated. Experimental results obtained from a laboratory 0.37kW reluctance machine driven by a dc motor are compared with the simulated results to validate the feasibility of the proposed method.
