Simulation Results

<p>An accurate model of balanced and unbalanced three-phase Induction Motor (IM) under balanced and unbalanced supply conditions based on Winding Function Method (WFM) is presented in this work. In this paper, the unbalanced condition in three-phase IM is limited to stator winding open-phase fault. The analysis of presented models is shown in details which allow predicting the performance of 3-phase IM under different conditions. Computer simulations were obtained using the MATLAB software for a three-phase squirrel cage IM. MATLAB simulation results show that the oscillation of the speed and electromagnetic torque has increased considerably due to the open-phase fault in stator windings.</p>

Good Agreement

This paper adopted a thermal network method (TNM) based on Motor-CAD with MATLAB/Simulink software, and finite element method (FEM) based on Motor- CAD with Flux2D software, to estimate the stator winding temperature of a totally enclosed fan-cooled (TEFC), squirrel cage, three-phase induction motor. The three software packages were adopted successfully with a good agreement among their results resulting in preferring using Motor-CAD in obtaining results, and using Flux2D with MATLAB to validate these results. The success of triple-software methodology will give the induction motor designer a well-validated tool in attaining a safe motor operation without exceeding the maximum allowable stator winding temperature rise, and without using an experimental test based on an expensive manufacturing motor.

Short Circuit Fault

The study addresses the problem of detecting a short circuit fault in the three-phase induction motor winding by monitoring the stator current Park vector (Lissajous curves). Park's vector model is implemented using the Matlab software package. The experimental part of the study was carried out on an 11 kW three-phase induction motor. The Lissajous curves obtained for a healthy motor and a motor with short-circuited turns under various load conditions were compared with each other. The obtained results have demonstrated the effectiveness of the proposed method for detecting interturn short circuit faults in the three-phase stator windings of induction motors.

This paper has proposed an approachwhich detects the stator turn to turn faults and phase to ground faults in stator winding of three induction motor. This method proposes analysis of stator winding currents for both normal and fault conditions. High frequency universal model of three phase induction motor used for MATLAB simulation. By using the wavelet MRA technique, the approximate and detailed coefficients of the faulty voltage and current waveforms of the machine are generated under different fault conditions. From the approximate coefficients the type of the fault has been identified. Depending on the energies of the signal the fault diagnosis can be done. The proposed protection scheme is reliable and fast for various fault inception angles

Novel Method

This paper investigates the vector control of a star-connected three-phase Induction Motor (IM) under stator winding open-phase fault. The used vector control method is based upon indirect rotor field-orientation concepts that have been adapted for this type of machine. Beside the implementation of this method in critical industrial applications, the proposed method in this paper can be used for vector control of unbalanced 2-phase or single-phase IM with two main and auxiliary windings. Simulation results are provided to show the operation of the proposed drive system.

Actual Point

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.

The Impact

Although a three–phase squirrel cage induction motor is known by its qualities of robustness and low cost of construction. However, this machine can be affected by potential defects that affect the production, safety, quality of service and profitability of installations. However, to show the behavior of induction motor in different operating modes, the studying of this machine is very important. This paper presented the results of an experimental investigation to see the impact of the open phase fault on the thermal behavior in the 2.2 kW three phase squirrel cage induction motor, and to display the stator current waveforms with healthy and faulty conditions under different loads.
