  • PSAT is a Matlab toolbox for static and dynamic analysis and control of electric power systems. The PSAT project began in September 2001, while I was a Ph.D. candidate at the Universit´ degli Studi di Genova, Italy. The first public a version date back to November 2002, when I was a Visiting Scholar at the University of Waterloo, Canada. I am currently maintaining PSAT in the spare time, while I am working as associate professor at the Universidad de Castilla-La Mancha, Ciudad Real, Spain. PSAT is provided free of charge, in the hope it can be useful and other people...

  • Harmonic distortion problems include equipment overheating, motor failures, capacitor failure and inaccurate power metering. The topic of power system harmonics was covered for the first time 20 years ago and the first edition has become a standard reference work in this area. Unprecedented developments in power electronic devices and their integration at all levels in the power system require a new look at the causes and effects of these problems, and the state of hardware and software available for harmonic assessment.

  • I have been undertaking the research and practical applications of power system optimization since the early 1980s. In the early stage of my career, I worked in universities such as Chongqing University (China), Brunel University (UK), National University of Singapore, and Howard University (USA). Since 2000 I have been working for AREVA T & D Inc (USA). When I was a full - time professor at Chongqing University, I wrote a tutorial on power system optimal operation, which I used to teach my senior undergraduate students and postgraduate students in power engineering until 1996.

  • In a normal alternating current power system, the voltage varies sinusoidally at a specific frequency, usually 50 or 60 hertz. When a linear electrical load is connected to the system, it draws a sinusoidal current at the same frequency as the voltage (though usually not in phase with the voltage). When a non-linear load, such as a rectifier, is connected to the system, it draws a current that is not necessarily sinusoidal. The current waveform can become quite complex, depending on the type of load and its interaction with other components of the system.

  • Power flow solutions are needed in both for planning and operation studies. Power flow studies for three phases balanced power system can be carried out using very efficient methods. Power flow analysis for certain type of power system network can be carried on by using several software that already been develop without manual calculation on this time. One of the software is MATLAB with its toolbox: Power System Analysis Toolbox. This software also uses numerical methods to do power flow analysis like Newton-Raphson and its modified form, Fast Decoupled Method.

  • In writing this book the author has been primarily concerned with the presentation of the basic essentials of power-system operation and analysis to students in the final year of first degree courses at universities and colleges of technology. The emphasis is on the consideration of the system as a whole rather than on the engineering details of its constituents, and the treatment presented is aimed at practical conditions and situations rather than theoretical nicety.

  • In industrialized countries, distribution systems deliver electricity literally everywhere, taking power generated at many locations and delivering it to end users. Generation, transmission, and distribution — of these big three components of the electricity infrastructure, the distribution system gets the least attention. Yet, it is often the most critical component in terms of its effect on reliability and quality of service, cost of electricity, and aesthetic (mainly visual) impacts on society....
