Abstract

Recently, there has been renewed interest in modeling of electrical machines for the Electro-Magnetic Transient Program (EMTP)-type programs, with the goal of improving the machine-network interface. In this paper, we present a new voltage-behind-reactance induction machine model for the EMTP-type solution and power system transients. In the proposed model, the stator circuit is represented in $abc $ phase coordinates and the rotor subsystem is expressed in $qd $ arbitrary reference frame. Similar to the recently proposed synchronous-machine voltage-behind-reactance model and the established phase-domain model, simultaneous solution of the machine-network electrical variables is achieved. Efficient numerical implementation of the proposed model is presented, in which one time-step requires as little as 108 flops, taking 1.6 $mu {rm s} $ of CPU time. Case studies of induction machine start-up transients demonstrate that the proposed model is more accurate and efficient than several existing EMTP machine models.
