Answer / saurav kafle

It is called static excitation when you make use of solid
state components like diode and thyristors to convert to
pure dc and to use this dc for field excitation of
synchronous generators. The field winding of synchronous
generators can be excited by dc source only. It is called
brushless excitation because use of carbon brushes are not
made here.It is called dynamic excitation is when you make
use of rotating brushes.

Excitation is necessary to produce reactive power and also
to regulate the voltage of synchronous generators.

Answer / mm

static excitation is stationary and contacts with rotor
winding through brushes , but dynamics rotates with the
rotor winding and it is with brushes or also brushless

Answer / ooomar

static excitation is stationary and contacts with rotor
winding through brushes , but dynamics rotates with the
rotor winding and no need for brushes

Answer / elec_maint

Both static and dynamic exciters, may use solid devices as
AC/DC converters. The key difference is that static type
feeding the field winding (F.W) via brushes, but in the
dynamic one the solid state converter is rotating with the
F.W, and the supply to the converter is induced from
external excitation stator windings.

THE STATIC AND DYNAMIC ARE BRUSH EXITATION THE DIFFIRENCE
ONLY STATIC USE FLASHING PATTERY UNTILL 10% FROM RATED
POWEROF GENERATOR BUT DYNAMIC EXITATION USE MAN AND PAILOT
