Answer / k.prakashchandra

When the generators(gen) are connected to grid or net work
,if all the gens are run at unity pf ,there will be drop in
voltage due to inductive load in the system as the current
increases.Then to maintain system stability, LDC requests
large generating stations to increase the voltage . This
will increase the KVAR and results in lower lagging pf in
the gens. That is why the gens are designed for 0.8/0.85
pf.The pf of gens can be kept at any value by varying
excitation or resetting in APF mode.As pf control is
required by generating stations,capacitor banks are not used
.Capacitor banks can be used in the system to reduce the
inductive load but not in the gen stations.

Answer / k.prakashchandra

Pf of generator can be brought to required value by varying
excitation.

Answer / k.prakashchandra

If the gen is connected to grid ,its pf can be regulated by
varying the excitation or by APF mode.

One more question can be use Capacitor Bank in Aux consumption panels in Thermal Power plant like CHP

Answer / k.prakashchandra

In the line 9, read as ' As pf control is not required'.

For an 100kw generator, only 50kw of load is connected. Will the generator generate only 50kw or 100kw. If it generate 100kw what happens to rest of the 50kw. What happens if we connect more than 100kw of load?
