These values get implemented with the zero sequence admittance matrix. Neutral-to-ground impedance for the generator. All three sets of values can be modified, either manually or by loading values from an external file using the Fault Analysis Dialog. By default, all three values are initially the same as the load flow internal impedance of the generator. These fields represent the internal impedance of the generator for all three sequences. By default, no internal transformer model is assumed. The resistance, reactance and tap setting for the generator step-up transformer, if one is being modeled internally with the generator. This value is used when calculating fault analysis values for the internal generator parameters.Ĭheck this check-box if the generator has the neutral grounded. ![]() ![]() The parameters on this tab are used when running a fault analysis study.
