FAULT ANALYSIS USING Z-BUS MATRIX – ALGORITHM
Bus impedance matrix is the inverse of the bus admittance matrix. The matrix consisting of driving point impedance and transfer impedances of the network is called as bus impedance matrix. Bus impedance matrix is symmetrical.
(i). Form bus admittance matrix and take the inverse to get bus impedance matrix.
(ii). Using bus building algorithm.
(iii). Using L-U factorization of Y-bus matrix.
