This thesis has been performed in order to earn a
master's degree in electrical engineering. The task was
to implement an automatic voltage regulator, AVR, to
control the terminal voltage of the synchronous
generator Svante at the Division of Electricity at
Uppsala University. The AVR uses Bluetooth
technology to transfer a control signal produced by a
programmable logical controller, PLC, to phasemounted SSRs that decides what proportion of the AC
from a six-phase brushless exciter that is to be used
for the magnetization of the rotor.
Test runs of the AVR were preformed with a regulator
optimized according to the Ziegler-Nichols method
and a static exciter that uses brushes and slip rings to
apply voltage to the rotor winding. The results
obtained complies with the assigned requirements set
for this thesis and the AVR.
The primary focus of this thesis mainly lies in the
construction of the control system, which include the
programming of both PLC and Bluetooth
communicating devices.
