Three–phase squirrel cage induction motors are the most widespread types of electrical motors which can be found in both industrial and tertiary applications. There are some reasons why they are so often used, such as simple construction, nearly maintenance-free, advantageous price and the possibility to feed them directly from the AC network. Even if their reliability is very high, some unexpected breakdowns can occur during their operation. In this paper, coil–to–ground faults of motor stator winding have been taken into consideration. These failures have been modelled in several points of one stator phase using COMSOL software. As seen from simulation results these failures have a significant impact on current distribution in stator phases causing changes in rotor currents, motor inner torque, speed, etc., depending strongly on the actual point of the failure.

“…In [20,21], a d-q model for induction motor is developed, then the transient waveforms are illustrated with respect to different reference frames. In [22], an α-β model for induction motor was developed to facilitate studying stator behavior during source interruptions. In [23], an etap model was developed to show the effects of the incoming induction motor on a neighboring load by comparing different starting methods.…”

This paper presents a modelling and experimental verification system for a group of induction motors during starting in medium voltage networks including its effects on other nearby running units in different operating conditions. The simulation model is based on a real-life case study which is an agricultural drain pump station. The dynamic model was built with MATLAB®/SIMULINK® where a thorough performance analysis can be achieved. For system verification, the simulation curve results were compared with real-life data curves which were recorded by a suitable device located on worksite. The verified model was used to perform six practical scenarios based on the real station's operating instructions. For each studied
