Question
Dear Expert,
Please explain what is the meaning of the term Master-Slave in a set of generators.
Thank you,
L.

Answer
Normally the set up is where the master is set up for the main load and governor and AVR settings.
The slaves are then connected in parallel to add to the out put "grid" to compensate for additional loads,
However this set up requires computer controllers and can be very expensive .
Normally 2 or 3 generators running by diesel engines are paralleled and synchronized together and the load is shared by adjusting the diesel RPM and AVR output and pf readings.
