voltage droop calculations

(OP)
how could i calculate the voltage droop? maybe i use Xd in example 10,9 ohms, and i multiply by current?
 

RE: voltage droop calculations

Droop is another name for proportional band in analogue control circuits. Droop may be electrical, mechanical, (RPM, position), pneumatic, or possibly some other variable.
If you want voltage drop, use Z (impedance) times I (current).

RE: voltage droop calculations

gaux,

Most generators have an automatic voltage regulator which modulates the field current of the machine to maintain a setpoint by using a feedback from VTs connected to the main terminals, or maybe connected to the load busbar or after a step-up transformer. It is the AVR which determines the droop characteristic: the AVR setpoint can be a constant value regardless of the load applied, or it can be made load-dependant by providing the AVR with an input from a CT on the main terminals of the machine. This latter mode is a voltage droop characteristic.
