How do determine the Size of a Droop Current Transfomer for
Paralleling of Two Generators, Say I need a Droop Current
transformer for a 600 kW generator need to be parallel with
a 800 kW generator, etc.
Answer Posted / satish babu
Consider two parameters to descide the CT ratings,
a) Primary current on the phase is 1050 amps,Consider No of
leads it has from the generator - If one cable is connected
your primary can be 1000A-1200A
If two leads are used , use only one lead as CT primary
then the CT primary can be 500-600 A
b) Your secondary can be 3A / 1A / 0.5A depending upon the
AVR used

A powerplant has 8 gensets operating in grid parallel mode. In one genset sometimes there is pf variation and kvar variation. The plant operates in pf mode. When this variation is observed the load is stable, voltage is also stable, freq and genset speed is also stable. How will you check the functioning of pf card.
