Computer Analysis of power Systems By Jos Arrillaga C P Arnold
In an earlier book entitled Computer Modelling of Elecfrical Power Sysfems the authors described some of the component models and numerical techniques that have established the digital computer as the primary tool in Power System Analysis. That book also included, for the first time, the incorporation of h.v.d.c. convertor and systems within conventional ax. power system models. From an educational viewpoint some of that material can be considered of a specialised nature and can be substantially reduced to make room for several other basic and important topics of more general interest.
After three decades of computer-aided power system analysis the basic algorithms in current use have reached high levels of efficiency and sophistication.
In this new book the authors describe the main computer modelling techniques that, having gained universal acceptance, constitute the basic framework of modem power system analysis.
Some-.basic knowledge of power system theory, matrix analysis and numerical techniques is presumed, although several appendices and many references have been included to help the uninitiated to pick up the relevant background.
An introductory chapter describes the main computational and transmission system developments which influence modem power system analysis. This is followed by three chapters (2, 3 and 4) on the subject of load or power flow with emphasis on the Newton-Raphson fast-decoupled algorithm. Chapter 5 describes the subject of ax. system faults.
The next two chapters (6 and 7) deal with the electromechanical behaviour of power systems. Chapter 6 describes the basic dynamic models of power system plant and their use in multimachine transient stability analysis. More advanced dynamic models and a quasi-steady-state representation of large converter plant and h.v.d.c. transmission are developed in Chapter 7.
A description of the Electromagnetic Transients Program with the marriage between ’Bergeron’s and Trapezoidal’ methods is presented in Chapter 8.
A generalisanon of the multi-phase models described in Chapter 3 is used in Chapter 9 as the framework for harmonic flow analysis.
Chapter 10 describes the state of the art in power system security and optimisation analysis. Finally, Chapter 11 deals with recent advances made on the subject of interactive power system analysis and developments in computer graphics with emphasis on the use of personal computers.
