Abstract:
This Thesis outlines a means of Frequency Response
Testing a Synchronous Machine by modulating a Pseudo Random Binary sequence
with the field current controllers phase angle delay on the rotor of a
synchronous machine. The machine will be on-line and possibly under load.
Using cross-correlation and Fast Fourier Transform
(FFT) techniques of the rotor input and stator output windings, a frequency
response model of the machine should be able to be obtained.
This Thesis includes the design and construction
of a fully controlled 3-phase bridge rectifier connected to the rotor of
a synchronous machine. The addition of a circuit to modulate a pseudo random
sequence with the rotor excitation current of the machine was completed
and perfected.
Pseudo random binary sequence behavior and characteristics
are explored in depth. Construction and frequency response analysis by
FFT is covered correspondingly. Frequency response tests are conducted
on the synchronous machine system by conventional means. Results obtained
conformed to how the system should act when compared with previous data
for the machine.
