Fault Analysis of Power Systems

In this chapter, short-circuit fault analysis of a power system is discussed. Both symmetrical three-phase and unsymmetrical faults are analysed to perform fault current calculations and power system stability studies.

Symmetrical fault analysis is carried out using bus admittance matrix, employing efficient solution techniques in MATLAB. For analysing unsymmetrical faults, symmetrical component transformation has been introduced while comparing it with Park transformations. Further, sequence impedances of power system components are detailed so as to build a sequence ...
