|Abstract:||<p>Recently the problem of dynamic instability has been increased due to the recent trends in synchronous machine design and the growth in the relative size of the power stations. In this thesis such a problem has been examined by analysing the damping and synchronizing torque coefficients. Different methods for calculating those torque coefficients have been reviewed, and a new method based on a more accurate representation for the machine has been developed. Because of the more detailed representation the new resultant torque coefficients permit the investigation of additional properties of those coefficients, as well as more precise analysis of the properties previously studied. The problem of weak or negative damping associated with the use of high gain and quick response static exciters has been given special attention. Different schemes for producing a stabilizing signal have been discussed. A design procedure for a stabilizer which assures successful operation over the whole generation range has been outlined.</p>|
