Economic operation of power systems [antikvár]

PREFACEThis book treats of new analytical and computing techniques which have resulted in significant direct annual savings in the production economy of electric utilities. The emphasis is upon theoretical developments and computer methods which supplement the practical skills of the electric utility engineer.The methods discussed here have been widely applied by electric utilities in both the United States and Canada. Improvements in fuel economy of approximately $50,000 per year per 1000 mw of installed capacity have been achieved in a number of systems by including the effects of transmission losses by means of the transmission-loss formulas given.Several powerful tools are described which should greatly enhance the engineer's capability of solving system problems. These are1.Matrix methods.2.Analogue and digital computers.Matrix methods are used to derive and calculate transmission-loss formulas. These matrix methods provide general methods of dealing with systems in a simple manner. They also lead to orderly computational procedures which are readily handled by digital computers. The application of analogue and digital computers to the problems of calculating transmission-loss formulas and generation schedules is also treated.The application of many of the principles incorporated in this book to automatic economic control of power systems is covered in my book Economic Control of Interconnected Systems, now in preparation. This companion work also considers energy accounting, control, and economic theories for economic operation of interconnected systems as well as the subject of economic operation of interconnected steam and hydroelectric systems.The present volume is based upon a course I have been giving since 1952 to participants in the General Electric Company's Power Systemsvii
