They show you how to construct the Z-bus for a large network without performing matrix inversion. One important attribute to building the Z-bus for fault analysis is that the generator subtransient reactances should be included. This means that it is necessary to include an additional bus for every generator in order to

This document summarizes a method for systematic fault analysis in power systems using the bus impedance matrix. The key points are: 1) The bus impedance matrix Zbus is derived by inverting the bus admittance matrix Ybus. 2) Given a fault at a bus k, the fault current Ik(F) and voltage changes ΔVbus can be calculated using Zbus.

\(\mathrm{Z_{bus}}\) can be determined by two methods: Determine \(\mathrm{Y_{bus}}\) and take its inverse. Directly formed from reactance diagram which requires knowledge of modification of existing \(\mathrm{Z_{bus}}\) matrix due to addition of new buses or addition of new line (or impedances) between existing buses \(Z_{Bus}\) Building Algorithm
