1.0 Creating a Job File – Subject Network

This document will illustrate how to create, modify and customize a single line diagram using DesignBase graphical user interface. The system shown in Figure 1 will be used as an example. As the actualstep by step process is explained, the user will be simultaneously introduced to a critical application

called the “Master File Editor”. This tool allows the user to control base-parameters and settings that arecritical during the modeling and analytical process of the job file.

1.4 The Generator Short Circuit Model

The impedances required by the editor are explained below and are entered as a percentage of thegenerator’s base voltage and kVA. The X/R ratio can be calculated from the generator time constant andarmature resistance information if provided. This calculation is based on equation 1. If this information isnot available, the user can select “Estimate X/R ratio” and the program will add a value based onaccepted IEEE standard curves.

%X”dV Rated-voltage (saturated) direct-axis sub-transient reactance. It is used for first-cycle andinterrupting time calculations.

%X’dV

Rated-voltage (saturated) direct-axis transient reactance. It is used for time delayed currents inrelay applications.

Xd Rated current unsaturated direct-axis steady state reactance.

%X”2V Rated-voltage negative sequence reactance. It is used to calculate the X/R ratio and forunbalance short circuit calculations.

%X0 Zero sequence reactance. It is used in unbalanced short-circuit calculation, when dealing withgrounded generators.

Ta3 Rated-voltage generator armature time constant in seconds. It is used to calculate the X/R ratio.

In some cases, the armature resistancea

R may be given instead.

%Ra Armature resistance.

The X/R ratio is determined from the following equations:
