Homework Help: Power Circle Diagram: Sending/Recieving End Voltages & Power Angle

  1. Sep 24, 2013 #1
    1. The problem statement, all variables and given/known data

    How does the angle and magnitude difference between the two ends of the transmission line effect the real and reactive power flow?

    2. Relevant equations

    3. The attempt at a solution

    See two tables of data points and plots attached.

    It seems as though for the sending end as we increase the power angle (from 0 to 40 degrees) we increase the amount of positive reactive and active power sent.

    For larger sending end voltages, we see larger reactive and active powers.

    The opposite seems true for the receiving end voltages.

    Am I understanding this correctly?
