I really need help understanding three phase systems. What can you tell me to make it more clear? When can a system be analyzed in its single-phase equivalent? Is it better/easier to have the load in the same configuration as the source? is power factor alwasy the cosing of the angle of the total impedance? Thank you
Shown are two buses connected via a transmission line. Connected to Bus 1 is a generator(modelled as a voltage source V1), and to Bus 2 is a generator( with Voltage V2) and a load. The line impedance Z = R + jX is not known. Three-phase load is forecasted as 100MW + 60MVar. Generator at Bus 2 is scheduled to deliver 40MW and its excitation is adjusted for the machine to deliver 55 MVar.
