Which system characteristic is NOT typically managed by a droop governor?

A droop governor is primarily utilized for managing frequency regulation and load sharing among generators in a power system. The droop characteristic allows a generator to adjust its output power in response to frequency variations in the grid, thus helping maintain system stability.

Load regulation refers to how well the system can respond to changes in demand. While droop governors help with this to an extent by regulating output in response to frequency, their main function is not focused directly on load regulation as that is more related to the overall system’s design and additional control strategies.

Frequency regulation is a critical function of a droop governor; it directly responds to changes in system frequency by adjusting generator output based on the droop setting. Output capacity, too, is related to the droop setting since it defines how much power the generator can provide in conjunction with its current frequency.

Voltage control, however, is not a characteristic managed by a droop governor. This function is typically handled by Automatic Voltage Regulators (AVRs) that adjust the excitation of generators to maintain voltage levels in the system, which is distinct and separate from the frequency-related actions of droop governors. Thus, the characteristic that is not managed by a droop governor is voltage control.
