Fault Analysis: Y-Bus Matrices
The Matrices page is where the positive, negative and zero sequence admittance matrices can be viewed for the fault. This data is only visible when a fault has been calculated. The three sub-pages on the Matrices page each have the same functionality as other Case Information displays. The purpose of each display is to show the admittance matrix for the specified sequence. One of the most important features of these matrix displays is the ability to right-click on the display to bring up additional display options in the local menu, including the ability to export the Y-bus admittance matrix to a Matlab M file, which allows import of the matrix into Matlab for additional manipulation, such as inverting the matrix to get the equivalent sequence Z-bus matrix.
