6. An 8 pole, 30 diesel generator has a line voltage of 450V at 62.5 Hz when its circuit breaker is open. At full load it supplies a line current of 410 Amps at a power factor of 0.83 lagging, its line voltage droops to 440V and the frequency droops to 60.0 Hz. The generator's full load efficiency is 85%. The efficiency of the diesel engine is 36%. a) What is the generator's % voltage regulation? b) What is the diesel engine's no load speed RPM, its full load speed RPM and its % speed regulation? c) What is the alternator's output apparent kVA, active kW, and reactive kVar power at full load?

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.
