Two power stations S1 and S2 are interconnected through a transmission line of per unit (p.u) reactance of 0.6. Station S1 has one generator of P.U. the reactance of 0.3, and station S2 has two generators of p.u reactance 0.6 each. For a 3 – phase symmetrical short circuit at the middle of the transmission line (point F). The change in the value of the equivalent fault reactance, with one of the generators of S2 removed, is _____ (in %).
    Correct answer is '20'. Can you explain this answer?

    Equivalent reactance with respect to fault point =(0.3 + 0.3) || (0.3 + (0.6 || 0.6))
    =0.6 || (0.3 + 0.3)
    = 0.3
    After removal of one of the generators of S2 with respect to fault point
    = (0.3 + 0.3) || (0.3 + 0.6)
    = (0.6) || (0.9) = 0.36
    Change in the reactance = 
    = 20%
