✦ Synopsis

This paper describes a phase model of an induction motor based on Transmission-Line Modelling technique. Its main advantage compared to the existing TLM d-q model is the possibility of using a small part of the stator self-inductance of each phase as a link model to connect the motor to external sources and drives. Unlike the d-q model, the phase model does not therefore require any additional components for connection purposes. The application of the phase model is demonstrated by an example representing a traction drive circuit. Identical simulation results to those obtained from a different study based on a d-q model are NOTATION Capacitance of the resonant filter Link capacitance Capacitance of the snubber i Damping or friction coefficient Current matrix Time derivative of [ I ] Current flowing through component or loop n Current flowing through phase n (= a, b, or c) of m (= 's' for stator or 'r' for rotor) winding Moment of inertia Inductance Inductance matrix Time derivative of [ L ] Inductance of the input AC reactance Inductance of the resonant filter Non-linear inductance Small inductance extracted from the stator self-inductance Resultant three-phase magnetizing inductance Total phase stator inductance Stator leakage inductance Mutual inductance between the stator windings Stator self-inductance of one phase Total phase rotor inductance Rotor leakage inductance Mutual inductance between two rotor windings Rotor self-inductance of one phase Unit inductance
