Improved synchronous source modelling with particular reference to the development of high speed protection.

Abstract

This study is concerned with improved power system models for use in the development of high and super speed distance protection. New protection techniques indicate the need for a precise system model which takes into account any distortions produced by both the source and transmission lines. The effect of unexpected and/or delayed zero-crossings of the voltage and current waveforms due to travelling and fully offset current waves are studied. A new technique utilising symmetrical components and the Fourier transform to analyse a system containing a large turboalternator, generator transformer and a distributed parameter transmission line is developed and compared with time domain phase coordinate solutions.
