Few power systems are isolated from the effects of high voltage DC transmission, and this technology figures prominently in their planning and operation. This new text, written by one of the world's leading authorities on the subject, covers the incorporation of AC DC converters and DC transmission in power system analysis. In addition to conventional power flows, faults and stability, AC DC power system analysis describes the simulation of power system steady-state waveform distortion and transient behaviour. Computer modelling of power electronic devices is given prominence as these programmes are central to power system design. The concepts and methods described in the book are also readily applicable to FACTS (flexible AC transmission systems) technology.
