A synchronous generator is supplying power to three motors through a transformer as shown below. The sub transient reactance values are known to be: Xg" = 0.20 Xm1 = 0.60 Xm2" = 0.30 Xm3" = 0.20 XT = 0.10 Each motor is consuming 0.5 pu power at a power factor of 0.8 lagging and the voltage at bus 2 is 1.020 pu G 1 M1 M2 FM M3 Determine Ybus for the system shown. Invert Ybus to obtain Zbus for the system shown. Draw the rake equivalent diagram when a bolted fault occurs on bus 2. Solve for the fault current and the voltage at bus 1 when the fault occurs. Having determined If and E, determine Ig, Im1, Im2, and Im3.
