Project Name: Dynamical Modelling of Synchronous Machines
Supervisor: Andrew Allison, David Vowles

Description:
This project aims to carry out a rigorous sequence of tests to measure the dynamical parameters of a synchronous machine. An important aspect of this project is the ability to capture and collate high-quality sets of measurements, and to combine these in order to estimate parameters. The other important aspect of the project is to model the synchronous machine (and prime-mover) to be able to predict experimental outcomes.

 A synchronous electric motor is an AC motor in which, at steady state, the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integral number of AC cycles. Synchronous motors contain multi phase AC electromagnets on the stator of the motor that create a magnetic field which rotates in time with the oscillations of the line current. The rotor with permanent magnets or electromagnets turns in step with the stator field at the same rate and as a result, provides the second synchronized rotating magnet field of any AC motor. A synchronous motor is termed doubly fed if it is supplied with independently excited multi phase AC electromagnets on both the rotor and stator.
