The effect of regulating elements on the dynamic behaviour of power systems

Abstract

This thesis describes the analysis of the dynamic performance of a complete hydro electric generating set under conditions of balanced three phase operation. The hydro generating set, or system, under consideration has been limited to a single synchronous generator, its control devices a shunt load at its terminals and a balanced three phase transmission line terminating at an infinite bus. Fig. 1.1 is an overall block diagram of this system. The system as shown in fig. 1.1 is a good representation of an isolated power station supplying power to a large central system via a high voltage transmission line, since the shunt load at the sending end of the line can be used to represent line changing capacitance as well as the local load. In this thesis a general analysis of this system will be produced and a means of reducing this general analysis down to any of the common special cases, such as voltage regulated synchronous machine connected to an infinite bus, will be provided.
