Owing to the use of Permanent Magnet Synchronous Motor (PMSM) widely in Electrical Vehicles (EVs), mandatory existence rotor angle sensor its control algorithm, higher reliability resolver than other instance, and eventually, significant effect errors on system stability, comparing two winding configurations is regarded analytically numerically following study. Firstly, employed assessment mode...

Problem statement: The Rotor reactance control by inclusion of external capacitance in the rotor circuit has been in recent research for improving the performances of Wound Rotor Induction Motor (WRIM). The rotor capacitive reactance is adjusted such that for any desired load torque the efficiency of the WRIM is maximized. The rotor external capacitance can be controlled using a dynamic capacit...

Tlie control of a doubly-fed induction machine (DFM) with a id without tlie use of a rotor position encoder is examined. First, a stator fliix linkage oriented control scheme for power and speed control, with a position encoder, shows the high performance control capabilities of this control arrangement and serves a s foundation for the sensorless scheme. The power-control method is then applie...

In this paper, a self-excited topology by utilizing third harmonic field excitation is proposed for realizing the brushless operation of Wound Rotor Vernier Machine (WRVM). The consists two windings housed inside stator periphery connected in series with three-phase diode rectifier. on are 12-pole and 4-pole armature winding. winding linked to open-end star help When current supplied inverter, ...

The paper proposes a novel method for improving performance of a Three Phase wound rotor induction motor using an indirect reactive current control scheme in the rotor. A 3 phase VSI with a dynamic capacitor is connected in the rotor circuit for controlling the reactive current in the rotor. The dynamic capacitor is an Hbridge switch with a capacitor in which the duty ratio of the Hbridge circu...

Energy is one of the most prominent factors in shaping the civilization of today. Under consideration for nonconventional energy source wind energy has turned out to be a leading source of energy. In recent years there has been a significant global commitment to develop a clean and economical alternative sustainable power source especially from wind. In this field of development wound rotor ind...

Abstract: This paper proposes an optimization based maximum power point tracking (MPPT) algorithm for selection of appropriate external rotor resistances of wound rotor induction generator (WRIG). The generator coupled with a Wells turbine is used in oscillating water column (OWC) wave power plants. The Wells turbine suffers with stalling behaviour that reduces the average output power signific...

This work is devoted to the investigation of oscillations in a drilling system using an induction motor with wound rotor as a drive. It is motivated by the problems of drilling rig failures in the oil and gas industry. The study is based on a modified version of the mathematical model of a drilling rig proposed by scientists from the Eindhoven University of Technology. The model of drilling rig...
