This paper presents a voltage-behind-reactance (VBR) induction machine model for the Matlab-Simulink toolbox SimPowerSystem, which is widely used for simulations of power and power electronics systems. In the proposed VBR model, the three-phase stator branches are represented by decoupled and constant R-L branches behind voltage sources, which provide a direct interface of the model with the external network-circuit. The rotor subsystem is expressed in the qd coordinates resulting in a high numerical efficiency. The VBR model has full-order and is otherwise algebraically equivalent to the classical qd model. We present case studies of induction machine interfaced with resistive and inductive networks. The studies show that the proposed model significantly improves the machine-network interface and enhances the numerical accuracy and efficiency as compared with the built-in SimPowerSystem qd machine model for the discretized solution of electrical circuit.
