    See figure attached for the question.

    Here is my attempt at the solution,

    1)

    |S| = |P + jQ|

    S = √((20k)² + (12k)²) = 23323.808 = √(3)VLLRMS*IlineRMS

    VLLRMS = 897.73V

    2)

    Since VLLRMS = VLNRMS = (mVdc)/√(2) = 897.73V

    Vdc = 1586.98V

    I'm pretty sure I've made a mistake somewhere I'm just not sure where.

    Any help?
