Abstract
Abstract
A device for measurement of power angle, rotor speed and terminal voltage of a
synchronous generator has been designed and realized. The device is supplying a signal
proportional to the phase angle between the terminal voltage and generated e. m .f. phases of the
synchronous machine. A second signal proportional to the rotor speed is also generated. These
output signals can be used for both measurement and control purposes. The device under
consideration can also be used in conjunction with digital converter (A/D) to perform on – line
computation and control.
The design and realization of the device depend on high speed digital and linear integrated
circuits. The time delays introduced by the device components are negligible compared to the
machine time constant, therefore the device is most suitable for applications in both transient and
dynamic conditions in synchronous machines.
The device is capable of monitoring the variations in the power angle and the rotor speed
for both measuring and control purposes. Further, this device can be used as a part of a digital
control system to provide stabilizing signals to digital automatic voltage regulator of synchronous
machines. The test and calibration results obtained show the capability of the device to monitor the
power angle and rotor speed in both steady state and transient conditions.
