Classification of Excitation System | Power Plants

The excitation systems can be broadly classified as: 1. DC Excitation System 2. AC Excitation System 3. Static Excitation System. 1. DC Excitation System: In dc excitation system, the system has two exciters—the main exciter (a separately excited dc generator providing the field current to the alternator) and a pilot exciter (a compound wound self-excited dc generator providing the field [...]
