Module 4 Synchronous Machines Two 3-phase, 11kV star-connected synchronous generators operate in parallel and supply a common load of 3000kW at a power factor of 0.8lagging. The synchronous impedance of the two generators are as follows: Synchronous impedance of generator 1: (0.9 +j15.8)22 Synchronous impedance of generator 2: (0.4 +j1.2)12 The excitation current of generator 1 is adjusted so that it delivers 150A at a lagging power factor, and the governors are set so that the mechanical load is shared equally between the two machines. + Q- Determine the power angle o (degrees) of generator 2.
