Summary

The objective of this book is to investigate the stability problems of power systems by using state-space analysis. The authors have aimed to meet the need for a book that would cover fairly briefly the theoretical and well as practical aspects of the problem, including up-to-date methods of calculation and stability improvement. When preparing the text, they have assumed that the reader has a basic knowledge (but not above graduate level) of network theory, matrix algebra and control theory. The book combines the simplicity and transparency of the classic stability principles with the advantages of modern treatment based on system theory and state-space techniques. Theoretical passages are always accompanied by analog or digital computer study results. Detailed analysis is given of voltage regulator and field governor effects as far as they influence the steady-state and/or transient stability of generating units. This is the first book in the field to treat in detail the stability questions of long distance, EHV power interconnections. In view of increasing precision requirements, the usefulness of different simplified stability models is widely dealt with.
