An investigation into the capabilities of three simulation tools for small-disturbance stability analysis

Includes bibliographical references (leaves 90-93).This MSc thesis forms part of more comprehensive research being conducted at the University of Cape Town comparing power system simulation tools. Part of the ongoing research at the University of Cape Town, which looks at solution methodology, power system component models and software flexibility using simulation tools not discussed in this thesis can be found in [4] and [7]. The objectives of this research are to investigate the capabilities of three power system simulation tools for small-disturbance angle stability analysis, namely PST, MatNetEig and CPAT Computers today have become fast, efficient with high memory capacities and advanced in data processing capabilities. Many power system simulation tools are available on the market and making a decision about which simulation tool to purchase has become complicated, especially with existing high competition between vendors. Once a decision has been made and the tool has been purchased, most users do not want to change to a new tool for several reasons. Firstly, learning how to use power system simulation tools is time consuming and secondly, the tools are very expensive
