Electric Power Systems, 4Th Ed

In this new edition the extended power system components chapter covers the synchronous machine, solid state excitation system, modern avr and flexible ac transmission systems (facts). Unified power controller, fast phase shifters, and voltage collapse and prevention are introduced. State of the art methods are included in chapters on load flows, fault analysis, system stability, and overvoltages and insulation coordination. A new chapter on power system economics and management covers esi reorganization and markets, spot pricing in generation, transmission distributions pricing principles, and it infrastructure and metering. Many current sections are rewritten with clearer explanations and all references are updated table of contents . Basic concepts. Components of a power system. Control of power and frequency. Control of voltage and reactive power. Load flows. Fault analysis. System stability. Direct-current transmission. Overvoltages and insulation requirements. Substations and protection. Basic power-system economics and management.
