✦ Synopsis

The effects of saturation in an induction motor's performance during a direct on-line start are studied using three different techniques. In the first method, the motor is modeled using the well-known Electromagnet Transients Program (EMTP) with saturation included in the magnetizing branch only. Secondly, the motor is modeled using PSpice, a popular circuit simulation software package, where magnetic-core saturation is modeled more accurately than in EMTP. In the final method, the motor is modeled by taking into account cross-as well as magnetic-core saturation and implemented in a dedicated computer program. A comparative evaluation of the results is presented.
