a generator and a battery whose voltages are respectively Eg=129.6 volts and Eb= 126 volts , are connected in parallel through line resistors to deliver power to a common load of 6 ohms. Line resistor for the generators is 2.85 ohms and its internal resistance is 0.15 ohms. For the battery, the line resistor is 2.8 ohms and its internal resistance is 1.2 ohms. Calculate the currents supplied by the generator and the battery, and the current taken by the load. Calculate also the load voltage Vl and the load power Pl.
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.
