Experimental Analysis of Noise and Vibration for Large Brushless Doubly Fed Machines
In this work, a large-scale Brushless Doubly Fed Machine (BDFM) built in frame size D400 is tested at different operating conditions in order to examine its noise and vibration levels. A series of measurements were conducted on the machine to establish the main modes of excitation of vibration and noise developed by the machine. The harmonic spectrums of the vibration amplitudes are presented a...
متن کاملEquivalent circuit for the brushless doubly fed machine (BDFM) including parameter estimation and experimental verification
Experimental results from a frame size 180 brushless doubly fed (induction) machine (BDFM) fitted with four rotor designs are presented. The machine is intended for use as a variable speed generator, or drive. A per phase equivalent circuit for the machine has been developed and a method of obtaining parameters for the circuit is described. Expressions for the torque as a function of speed have...
متن کاملControl Methods for Doubly-Fed Reluctance Machines
The paper considers aspects of scalar V/f control, vector control and direct torque (and flux) control (DTC) of an emerging cost-effective technology for limited speed range applications the brushless doubly fed reluctance machine (BDFRM). Apart from giving a comprehensive review of the various control methods, its major contribution is the presentation and experimental verification of a sensor...
متن کاملBrushless Doubly-Fed Reluctance Machine Optimization using Reluctance Networks
The Brushless Doubly-Fed Reluctance Machine (BDFRM) is being considered as a viable generator alternative to be used in wind turbines. However, a literature review shows that there is still a lack of researches to define a design procedure to make this machine commercial. This paper aims to address this issue by considering a new BDFRM design method using a reluctance network approach with focu...
متن کاملBrushless Doubly-Fed Induction Machine as a Variable Frequency Transformer
VFT (variable frequency transformer) has been recently used as an alternative to HVDC (high voltage direct current) to control power flow between asynchronous networks. VFT consumes less reactive power than a back-to-back HVDC system, provides faster initial transient recovery, and has better natural damping capability. VFT is simply a DFIM (doubly-fed induction machine) where the machine torqu...
