DC Excitation System Working Principle: 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 current to the main exciter).
The primary function of an excitation system is to provide a controlled direct current (DC) voltage to the generator's rotor windings, creating a magnetic field within the rotor. This magnetic field induces an alternating current (AC) voltage in the generator's stator windings, which is then sent to the electrical grid. What is Excitation System?
Thus, the excitation system controls the output voltage of the generator by adjusting DC current to the generator field winding. Excitation systems have two general classifications - rotating exciters or static exciters. Static Exciters include compound sources and potential sources, and have different characteristic than rotating exciters:
The components and functions of an excitation system can be summarized as follows, with explanations of their roles in ensuring stable and safe generator operation: Function: The exciter provides a direct current (DC) power supply to the generator's field winding.
