If Dg set is running parallel with grid we can adjust the
power factor through excitation, but if it is running in
ideal mode we cant adjust the power factor through
excitation, so we need capacitor bank at that time.

If there is major % of Voltage harmonics in the system, how can it be control or reduced?
