Question

The nature of excitation voltage control is​

Answer 1

Answer:

The basic function of an excitation system is to provide necessary direct current to the field winding of the synchronous generator. The excitation system must be able to automatically adjust the field current to maintain the required terminal voltage.

Answer 2

The nature of excitation voltage control is​ adjustment of field current.

Explanation:

• The primary function of an excitation system is to supply direct current to the synchronous generator's field winding.
• To maintain the appropriate terminal voltage, the excitation system must be able to automatically alter the field current.
• The quantity of electric energy (D.C) sent into the field winding of an alternator rotor to create magnetic flux / field is referred to as an excitation voltage or current. Self-excited alternators are those that generate their own excitation voltage.
