STEP 1: Enter the number of lines in a power system. Then, click on the “Generate Line Table” and fill the details of lines i.e., From, To, R(pu), X (pu), B/2 (pu).
Note: Line data for a standard IEEE 5-Bus system is provided. Click on “Autofill IEEE 5-Bus Lines”.

STEP 2: Enter the total measurements data in a power system. Then, click on the “Generate Measurement Table” and fill the measurement data i.e., Type (1=Voltage, 2=Real power injection, 3=Reactive power injection, 4=Real power flow, 5=Reactive power flow), From, To, Value, and Rii (error in measurement).
Note: Measurement data for a standard IEEE 5-Bus system is provided. Click on “Autofill IEEE 5-Bus Measurement Data”.

STEP 3: Enter the value of “Tolerance” and "No. of Iteration". Click on “Run State Estimation”. The values of the states estimated will be displayed i.e., Bus: Voltage magnitude (V (pu)) and Angle (degree).
