Six-phase doubly fed induction machine-based standalone DC voltage generator

Autor: Paweł Maciejewski, Grzegorz Iwański

Publikováno v: Bulletin of the Polish Academy of Sciences: Technical Sciences, Vol 69, Iss No. 1 (2021)

The paper presents a multi-phase doubly fed induction machine operating as a DC voltage generator. The machine consists of a six-phase stator circuit and a three-phase rotor circuit. Two three-phase six-pulse diode rectifiers are connected to each th

Characterization of flow interactions in an axial fan stage

Autor: Adel Ghenaiet

Publikováno v: Engineering Reports, Vol 2, Iss 12, Pp n/a-n/a (2020)

Abstract The aim of this study is to characterize the steady and unsteady flows of a high‐speed axial fan stage and assess its aerodynamic performance parameters. The flow unsteadiness is related to the stator‐rotor interaction originated mainly

Development of a Simulation Model of a Self-Energizing Hydraulic Brake to Actively Compensate Brake Torque Oscillations

Autor: Petry, Matthias, Reinertz, Olivier, Murrenhoff, Hubertus

Publikováno v: 10th International Fluid Power Conference (10. IFK) March 8-10, 2016. 1:535-546

Friction force oscillations caused by changing properties of the contact zone between brake disc and pad are well known from various applications. Resulting effects like brake judder are known phenomena in brake technologies and in the scope of vario

A Novel Method for Harmonic Current Injection with Sensor Supported Adaptation on Permanent Magnet Synchronous Machines

Autor: Matthias Vollat, Dominik Krahe, Frank Gauterin

Publikováno v: Machines, Vol 9, Iss 8, p 139 (2021)

To reduce torque oscillations in electric motors, harmonic current injection (HCI) has been used in industry for some time. For this purpose, higher harmonic currents calculated in advance are injected into the machine. Since the general conditions f

A new method of virtual direct torque control of doubly fed induction generator for grid connection

Autor: Mahmoud Zadehbagheri, Tole Sutikno, Mohammad Javad Kiani

Over the past few years, due to the shortage of fossil fuels and their unwanted environmental impacts, the use of renewable energy has vastly increased. Among them is wind power, which has been at the center of attention as one of the most important

Sustainable operation and performance improvement of grid connected DFIG during symmetrical faults using fuzzy controller based enhanced field oriented control

Autor: D.V.N. Ananth, G.V. Nagesh Kumar

Publikováno v: Cogent Engineering, Vol 3, Iss 1 (2016)

According to modern grid regulations, doubly fed induction generator (DFIG) needs to operate without losing synchronism during grid faults. But, severe fault leads to rise in stator and rotor current to a higher value and generator will get damaged.

Prognostics and System Health Management Conference (PHM)
Prognostics and System Health Management Conference (PHM), May 2020, Besançon, France. pp.0

International audience; This paper proposes a novel method for the prediction of stator current modulations applied to the detection of load torque oscillations in asynchronous drives. In faulty cases, the stator current presents amplitude and phase
