What is Droop on an AC alternator on a generator? Why

The droop system works by measuring the system load with a droop CT. This is connected to the AVR and as the load increases, it attempts to reduce the voltage by a small percentage (typically 3% from 0-full load at 0.8pf) and this therefore reduces the voltage.

Droop Characteristics

Droop characteristics refer to the relationship between the output frequency of a generator and its active power output, typically expressed as a percentage change in frequency per unit change in power. This concept is crucial for ensuring stable operation in power systems, as it enables generators to share load and regulate system frequency effectively. By adjusting their output
