STEP 1: Enter the number of buses in a power system. Then, click on the "Generate Bus Table" and fill in the bus details:
Bus Type (Slack Bus = 1, PV Bus = 2, PQ Bus = 3), Voltage magnitude (pu), Angle (degree), Pgen (pu), and Pload (pu).
Note: Bus data for two standard IEEE bus systems are provided — (I) IEEE 5-Bus and (II) IEEE 14-Bus. Use "Autofill Bus Data" buttons to load sample data.
STEP 2: Enter the number of lines in a power system. Then, click on the "Generate Line Table" and fill in:
From Bus, To Bus, X (pu), Line Limit (pu).
Note: Line data for IEEE 5-Bus and IEEE 14-Bus systems are also available through the "Autofill Line Data" buttons.
STEP 3: Click on "Calculate B-Bus Matrix for DC (Linear) Power Flow" to display the B-Bus matrix values.
STEP 4: Click on "Run DC (Linear) Power Flow: Base Case" to display bus voltage, angle, generation, load, and line flow data.
STEP 5: Click on "Run Contingency Analysis: Line Outages" to analyze line outage effects. Overloaded transmission lines will appear in red.
STEP 6: Click on "Run Contingency Analysis: Generator Outage" to analyze generator outage effects. Results for bus voltage angle, generator output, and line flows will be displayed, with overloaded lines highlighted in red.
