Power flow calculation

  1. Feb 12, 2014 #1
    1. The problem statement, all variables and given/known data

    If a 3 bus power system with buses A and B as generator buses and bus C as load bus.
    Power injection at bus A is 30 MW, at bus B is 60 MW and at bus C 90 MW withdrawal. Impedances in the 3 transmission corridors B-A, A-C and B-C are equal, i.e. X1 = X2 = X3. What is the power flow in each of the 3 transmission corridors?
    Note: power flow direction in transmission corridors is indicated as B-A, A-C and B-C.


    2. Relevant equations



    3. The attempt at a solution

    I assumed that equal impedances makes the power injection at bus B be equally divided bet. the 2 transmission corridors B-A and B-C, i.e. Power in B-A is 30 MW and in B-C is 30 MW and in A-C is 30 + 30 = 60 MW.
    Is my assumption correct?
