What this block does
Connects the authorized load or frequency request to the selected governor control path.
A simple example
In a microgrid power station, the controller can request an additional generator when available reserve falls and later unload a selected machine before its documented stop sequence. For this reference, the drawing identifies “Authorized governor demand” at the input and “Governor reference input” at the output. The interface differs between generator controllers.
What the drawings help you do
Start at the named input: Authorized governor demand. Identify its source device or document and the state represented on the drawing. Follow the named output: Governor reference input. Cross-reference its destination and separate the command from confirmation that the equipment responded.

What it represents
Connects the authorized load or frequency request to the selected governor control path. Generating-set coordination decides which available machines should operate and how their power contribution is shared. Engine starting, breaker connection, load acceptance and stopping are separate stages with their own feedback.
In a microgrid power station, the controller can request an additional generator when available reserve falls and later unload a selected machine before its documented stop sequence. For this reference, the drawing identifies “Authorized governor demand” at the input and “Governor reference input” at the output. The interface differs between generator controllers.
Preserve the engine and generator electrical boundaries, command authority and source readiness. Starting duty, minimum loading, synchronising, fuel systems and cooling behavior require the selected generator documentation. The functional block is an independent explanation of this named application. Equipment-specific ratings, terminal connections and operating conditions must be established in the project documentation.

Information to show or reference
- Label the source and connection reference for authorized governor demand.
- Identify the destination and defined state of governor reference input.
- Record the equipment or control-document revision supporting this functional block.
- Check this application limit in the project design: The interface differs between generator controllers.
A distinction that matters
The interface differs between generator controllers. This reference describes the named application; it does not establish a new IEC graphical symbol, an ANSI device-function number or an exact manufacturer connection diagram.
