Genset controller

A genset controller starts and stops the engine, monitors engine sensors, provides generator protection functions and, in paralleling versions, synchronises the set and shares load with other sources. Automatic mains failure versions also monitor the utility supply and control the changeover.

Drawing use: SLD / Schematic
Application: Microgrid systems
Reference family: IEC / IEEE / ANSI

A distinction that matters

A genset controller handles one set; a microgrid controller coordinates many sources.

Symbols

Diesel generator set

A diesel generator set combines a diesel engine, an alternator, a controller and usually a generator breaker into one package. On a microgrid single-line diagram it is the dispatchable source that sets voltage and frequency when the utility is absent, or that supports the battery during long periods of low renewable output.

Application: Microgrid systems
Reference family: IEC / IEEE / ANSI / Manufacturer

A distinction that matters

A diesel set uses compression ignition and liquid fuel; a gas engine set uses spark ignition and gaseous fuel with different load-acceptance behaviour.
