Abstract:

The concept for using frequency response methods to analyse synchronous machines has been developed since the 1950s. During this time, it has become apparent that frequency response methods are of major benefit in determining machine parameters, especially over the more traditional methods of sudden short circuit and open circuit tests. Although most current methods in parameter determination have not been generated without complex flaws. This thesis investigates the possibility of developing a computer program which uses an analytical approach to accurately extract pole-zero pair time constants from machine transfer functions.

This thesis demonstrates a program "Extraction", that uses an operator based design to allow for the determination of time constants and their related variables. "Extraction" behaves akin to most WINDOWS based programs and applications; techniques and lanuages for GUIs with an attributed windows style are investigated. The program uses various different interfaces so that an operator can select the best or most appropriates time constants for a system. Methods to determine the best and most appropriate time constants will be investigated and discussed.

In this program there are three distinct variable selection modules, phase selection, phase variable manipulation and delete module. Utilising the delete module, the program has ability to remove any particular set of time constants and their related data which have been extracted from a machines transfer function. Each of these selection modules is capable of changing and varying the selected data so that the most appropriate time constants are chosen.

This thesis will discuss all the above mentioned issues, as well as discuss further avenues for development.
