摘要: In this paper, the Routh criterion has been used to analyze stability of a self-excited induction generator-based isolated system which is regarded as an autonomous system. Special focus given load capacity generator. The state matrix generators with resistor-inductor established based on transient equivalent circuits in stator stationary reference-frame. recursive table by characteristic polynomial coefficients matrix. According criterion, necessary and sufficient condition predict critical loads deduced, from impedance can be calculated. A simple power built up 2.2 kW theoretical analysis experiments were all carried out platform. range determined minimum excitation capacitance (Cmin) maximum (Cmax), under various factors have agreement calculated results experimental demonstrate effectiveness accuracy proposed method. conclusions achieved lay foundation for further application systems analysis.
