Answer Posted / 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.
