1

4

Permanent Magnet

Rotor

Stator

Excitor

2. What part of the control system determines the load taken by a generator package?

The Governor and fuel valve

The exciter

The AVR

3. Does the AVR control a generators Power Factor when in Island Mode?

Yes

No

4. Identify the 3 parameters that have to match in order to run two generators in parallel

Speed

Fuel

Voltage

Current

Frequency

Phase

5. Why is 3 phases used?

More constant and consistent power delivery

180 degree phase shift between voltage and current causes more power

120 degree phase shift between voltage and current causes power to never fall to zero

Most economic and efficient design in terms of weight and complexity
