The microgrid of Figure 6.46 is supplied by an induction generator. The system has a local load rated 100 kVA at power factor rated 0.8 lagging. The three-phase transformer is rated 11 kV/0.44 kV, 300 kVA, and reactance of 6%. The induction machine rated at 440 V, 60 hz, three- phase, eight-pole; 500 kVA, 440 V, 60 Hz; stator resistance of 0.1 Q2/phase; rotor referred resistance in the stator side of 0.1 2/phase, stator reac- tance of 0.8 2/phase; rotor referred reactance of 0.4 2/phase. Compute the following: i) Compute the per unit power flow model and short-circuit model based on a base of 500 kVA and 440 V. ii) If the speed of the induction generator is 1000 RPM, what is the rotor frequency? iii) The flow of active and reactive power between microgrid and the local power grid.
