ABSTRACT
The project of "An Automated Synchronizing System For Electrical
Machine Laboratory" is conduct to enhance knowledge of the synchronizing
requirement for the three phase synchronous generator connected to TNB main in
Lab View graphical user interface. The project is also able to display in real time
reading for three phase voltage waveform, frequency, phase sequence and phase
difference in the synchronization system.
This project contains two parts which are hardware development and
software development. The purpose of the project is to observe and control the
synchronization condition automatically. This is done by using the hardware of
signal conditioning system to obtain the suitable output to be connected to input of
the data acquisition card (DAQ). LabView software is used to program and display
the output virtually on the computer and to control the control system to achieve
synchronization. The project uses closed loop control system concept, where ｴｨｾ＠
program will process the data of Vrms, Frequency, phase sequence and phase
difference. After that, this parameter will be compared between both synchronous
generator and utility main. This project will focus on two synchronization criteria,
which are speed control and phase sequence. The program will control the speed of
DC motor to do automatic adjustment if it does not achieve the synchronization
requirement. Furthermore, it will perform automatic swap to correct phase sequence
if the phase sequence is different with the TNB main. The program is also able to
trigger the hardware synchronization switch to tum on once the systems achieve the
synchronization requirement.
