Abstract

A general motor modelling method for transit system simulation studies J.G. Yu, R.W. Sturland & L.R. Denning CEGELEC Projects Limited, Boughton Road, Rugby ABSTRACT This paper describes a general motor modelling method for transit system simulation studies. The method is based on a tabulated data approach. It has been applied to an existing multi-train simulation package for both DC and AC motor drives (including linear motor drives). 1. INTRODUCTION Computer simulation studies have gained wide applications during both design and operations of transit systems in the last two decades [1,2]. With all simulation programs, traction motor modelling plays a very important role in representing the dynamic interaction between train motions and power supplies. Past work in this field has mainly involved DC traction motors, which are usually modelled on the basis of a three-region control strategy describing control schemes ranging from rheostat-controlled motors to GTO controlled
