Answer Posted / pintoo

the data u have given is not sufficient to calculate the
FLC.
the exact formula to calculate FLC is:
P=sqrt(3)*V*I*cos(phi)*efficiency

I=P/[sqrt(3)*V*cos(phi)*eff.]

P=30KW=30000Watt
V=415V
cos(phi)=?
eff.=?

put the value of cos(phi) and efficiency then u will get
accurate FLC.

Why reactive power is needed in a power system? How is it being absorbed or delivered by alternators? For reactive power control we are changing excitation but reactive power absorbing or delivering related to stator. How these two are interlinked? i want a detailed explanation with necessary expressions and figures?
