Abstract

Abstract : Load connection and disconnection are important factors for a comprehensive investigation on the performance of induction generators, providing theoretical foundation and technical support for the optimization of system configurations and safeguard measures. Based on the transient equivalent circuits of self‐excited induction generators under the two‐phase stationary reference frame, steady‐state motion equations are derived through the steady‐state operation analysis. The analytical computation of the motion equations successively gives the necessary condition for the loaded operation, the sufficient condition for the transient operation under a given speed, and the necessary and sufficient condition for the buildup arrival to steady states. Using the holistic analysis approach based on Lyapunov stability theory, this study presents a theoretical analysis approach for transient processes and analytically solves the load ranges under the specified performance indices. Good agreement between experimental and theoretical results verifies the correctness and validity of the theoretical analysis approach and its analytical conditions with better practicability and referenced values in engineering. © 2016 Institute of Electrical Engineers of Japan.
