Abstract :
A novel approach based on eigen techniques (eigenvalue and eigenvalue sensitivity) to determine minimum loading resistance of an isolated self-excited reluctance generator (SERG) is presented in this paper. A d-q axis equivalent-circuit model is employed to derive the dynamic equations of the studied SERG. Both dynamic performance and steady-state characteristics of a SERG under minimum loading effects are investigated. Experimental results obtained from a laboratory 1/2 HP (0.37 kW) reluctance machine driven by a DC motor are compared with the simulated results to validate the feasibility and effectiveness of the proposed method
