No load transmission line

  1. Nov 21, 2011 #1
    1. The problem statement, all variables and given/known data
    I was given all the full load stats of a long transmission line(100km) Vs, Is etec and i need to find the N0-load Vr and Is and no load Power consumed


    2. Relevant equations

    Im not entirely sure how to handle this, i would think, sense there is no load Vr and Vs are the same, and Is should now be lower because no load would draw less current, but im not sure how to calculate it.

    3. The attempt at a solution
    My line at load draws 100MW of power and has a Is of 166.1∠2.28 A. My Vs is 201.3∠1.72 kV
    and my Vr at load is 199.2∠0 kV, pf of 0.9.

    Like i said im not sure where to start
