Abstract
Abstract:
In this work a single chip microcontroller AT 89C51 is programmed in an
assembly language to regulate the terminal voltage of a synchronous generator
practically. The output of the microcontroller is as pulse width modulation (PWM)
which drives a static exciter as power transistor chopper circuit. The PWM is generated
from microcontroller utilizing the timer and programmed in such way that produces
duty cycle as a function of the error between reference signal and a measured terminal
voltage.
The reference voltage has a two part 8+4 bit string and the measured also consist of
two parts 8+4 bit string, the absolute error between reference strip and measured strip is
computed for each part of the signal individually.
The result shows that when a drop in terminal voltage occur the regulator reject
this effect and goes back to its set value as fast as possible.
