To ensure stable operation of a power system, it is necessary to analyse the power system performance under various operating conditions. Analysis includes studies such as power flow and both steady-state and transient stability. To perform such studies requires knowledge about the models used to represent the various components that constitute an integrated power system. In situations where there is a risk of loss of stability, it is necessary to apply controls that can ensure stable and uninterrupted supply of electricity following a disturbance. The subject of stability thus encompasses modelling, computation of load flow in the transmission grid, stability analysis under both steady-state and disturbed conditions, and appropriate controls to enhance stability. All these topics are covered in this book, providing a comprehensive treatment of the overall subject of stability of power systems. Topics covered include modelling of the synchronous machine; the synchronous machine connected to power systems; modelling of transformers, transmission lines and loads; power flow analysis; optimal power flow; small signal stability; transient stability; transient energy function methods; artificial intelligent techniques; power system stabilizers; series compensation; shunt compensation; compensation devices; and recent technologies. The subject matter is covered at a level that is suitable for students, scientists and engineers involved in the study, design, analysis and control of power systems.Biografía del autor:
Abdelhay A. Sallam PhD is a life Senior member of the IEEE and Professor Emeritus of Electrical Engineering at the Port-Said University, Egypt. Dr Sallam has taught courses in power systems, computer methods in power system analysis, conventional machines, distribution systems, logic circuits, and microprocessor structure. In addition, he has served as a consultant, advising companies on the design and installation of power networks, substations, and electric distribution systems. Om P. Malik FIET, LFIEEE has taught and done extensive research in the area of rotating electric machines, adaptive and AI control, and digital protection of power systems. He was a pioneer in the development of adaptive controllers for realtime applications to improve power system stability and such controllers are employed as power system stabilizers on large generating units.
