Answer / l.l

Droop CT is used to control load sharing of the reactive
power between paralleled generators. Its output is mixed
with the phase voltage to result in a signal that will be
proportional to the lagging power factor. This is used to
adjust the excirtation current accordingly so that the
proportion of reactive power is shared between them.

Answer / venkat

Power factor maintain ( Reactive kvar)

Answer / sachin

Droop C T gives pulse to avr for maintain the voltage on
load and reduce the fluctuation of voltage on load

can alternators work at leading power factor?

Hello, I am just preparing my self for a university interview and struck on the 11kv ring main unit system network. I just know that ring main unit has total three breakers, fuses and use to supply a power to any load/ building without any interrupt. But i am not be able to visualize the connections, either Ring main unit getting power from two different power sources? or there is always one feeder in complete ring circuit??? I would be highly thanks full of you help me.
