What is the purpose of 'automatic voltage regulation' (AVR) in a ship's generator?

The purpose of automatic voltage regulation (AVR) in a ship's generator is to maintain a stable and consistent output voltage despite variations in load and prime mover speed. A stable voltage is essential for the proper operation of all electrical equipment connected to the generator. When the load on the generator increases, the output voltage tends to decrease due to the increased current flow and the generator's internal impedance. Conversely, wh....
