六、(16%)計算題A60-Hz three-phasesynchronous getor ott H= MMVA and a direct axis transient reactance Xd =0.3 p.u. is connected to an infinite bus through a purely reactive circuit as shown in Fig. 3. Reactances are marked on the diagram in a common system base. The generator is delivering real power Pe= 0.8 p.u. and Q=0.074 p.u. to the infinite bus at a voltage of V=1 p.u.
