Why is self excited generator has a better regulation?

A self-excited generator has better regulation because it utilizes its own generated voltage to maintain the excitation of the field winding, allowing it to adjust automatically to changes in load. This inherent feedback mechanism helps stabilize the output voltage under varying conditions. Additionally, the generator can respond quickly to fluctuations, ensuring consistent performance and reducing voltage drops. Overall, this self-regulating capability enhances efficiency and reliability in power delivery.
