1. Vinning Diagram - Display of all possible voltages and phase angels in the load bus. Lines at .5 pu, 1.0 pu, and 2.0 pu. The white dot indicates the correct solution to the load flow calculation, the black dot represents the spurious solution.

  2. Menu bars to change values of P and Q in load bus or values of R and X in lines.

  3. Values of P and Q for correct and spurious solution.
