b) An 415V (Vine) three-phase power system is shown in Figure 2. It consists of a 415V Y- connected three-phase generator connected through a three phase transmission line to a Y-connected balanced load. The transmission line has an impedance Zline of 0.5 + j0.9 Q/phase and the load has an impedance Zload of 12 + j9 22/phase. i) Draw the equivalent circuit per phase. ii) Determine the three phase line currents in complex form. iii) Calculate the total active power (P) supplied by the generator. iv) Calculte the generator power factor. a ILA b IL С lu Zune Zune Zuine Figure 2 ZLood Zload Zload

Synchronous Generator

In comparison to an asynchronous generator, it is a machine where the rotor speed is equal to the rotating magnetic field produced by the stator, i.e., mechanical speed is equal to the electrical speed, thus called synchronous, and not asynchronous.

Salient Pole Rotor

Salient pole rotor includes a large number of exposed poles mounted on a magnetic wheel. The construction of a bright pole is as shown in the image on the left. The proposed poles are made of metal laminations. The rotor winding is provided on these poles and is supported by pole shoes.
