Single-phase squirrel cage and three-phase induction electromotors are the most popular electromotors used in industry from long ago. When an induction motor starts with direct connection method, it takes a lot of current from the power supply (several times the nominal current); so, several methods have been devised to start such electromotors. These methods either reduce the voltage of the st...

The proper orthogonal decomposition (POD) approach is applied to a linear finite element (FE) model of squirrel cage induction machine. In order obtain reduced valid on the whole operating range, snapshots are extracted from simulation typical tests, such as at locked rotor and synchronous speed. Then, machine used simulate different points with variable rotation speed, results compared full FE...

Renewable energy will play a vital role in greenhouse gas emissions reduction. However, renewable is located far away from the load center. Modular multilevel converter-(MMC) based VSC-HVDC systems became competitive for remotely grid integration. Unlike average model MMC and side converter, this paper presents detailed model-based control analysis of MMC-HVDC system solar wind Furthermore, it ...

Multiple coupled circuit modeling (MCCM) of squirrel-cage induction motors (SCIMs), or winding function approach is the most detailed and complete analytical model used to analyze the performance of faulty SCIMs. Already, in variate papers this approach was used to 3phases SCIMs, but this paper extends the above-mentioned model to 6phases SCIMs. Various simulations of variative faults are carri...

AC+DC hybrid microgrids are robust cost-competitive solution for poorly areas, as can be found in rural or island electrification. versatile proposed this work developed around wind turbine based on particular induction generator with double stator winding squirrel cage ...

Undesired secondary effects occurring at inerter-fed squirrel cage induction motors are investigated by a transient two-dimensional finite element analysis with coupled electrical circuits. Calculated time-dependent numerical courses are compared to measured ones. A novel and deeper insight into the invoked harmonic spectrum of the electrical stator current and the mechanical torque at the rota...

This paper deals with the finite element analysis of a specific fault of the squirrel cage induction motors consisting in rotor bars breaking. Several variants of rotor bar faults are studied, using both quasi-static and transient magnetic field analyses. The numerical results in the reference case of healthy motor are experimentally validated by laboratory measurements.

This paper is devoted to the modeling and dSPACE implementation of three-phase squirrel-cage induction motor control using the constant Volts per Hertz principle and rotor flux oriented control (RFOC) strategy. A fuzzy PI controller is used in the speed control loop. Experimental results are compared for two different controls using a dSPACE system with DS1104 controller board based on digital ...
