A challenging power electronics question involving generators and transformers?

  1. Aug 18, 2011 #1
    1. The problem statement, all variables and given/known data

    A 3-phase, 10KV, busbar of a power station is divided into three sections joined by two reactors as shown in Figure 1. Each section contains a synchronous generator and supplies a transmission line through a transformer. The parameters of genera-tors, reactors and transformers are given in Figure 1. Calculate the maximum initial fault line current which can flow into the fault, if a 3-phase short-circuit occurs in: A

    here is the digram :

    2. Relevant equations

    3. The attempt at a solution

    Can anyone help me with the relevant equations for this, and the way to tackle this problem?
