Negative Droop; As has been stated, all mechanical governors use droop, either constant or in the case of isochronous governors temporary, to achieve stable engine control. It is possible to adjust negative droop (speed reference increases as load increases) into some governors.

What part will my governors play in maintaining the plant? No need for manual increase. The governors will maintain speed or load proportion by increasing fuel flow automatically. The first unit on line will probably be operating isochronously to regulate freqquency, subsequent units will operate in droop mode.;

Voltage droop is usually expressed as the percent change in voltage from no-load terminal voltage as the reactive load varies over the full reactive load range. The concept of frequency or speed droop: from a no-load frequency condition, as real load is added the the prime mover slows and the frequency lowers.

For this reason, isochronous governors are typically provided with a so-called "droop" function, where droop can be defined as a governor characteristic that permits thesteady state engine speed to decrease slightly as engine load increases.

This Code specifies procedures for conducting tests to determine the following performance characteristics of hydraulic turbine speed governors: (a) droop: (1) permanent, (2) temporary; (b) deadband and deadtime: (1) speed, (2) position, (3) power;
