Gas Engine Module ​

Installation ​

TODO

Engines are added by selecting "Create new installation".

Installation Details ​

TODO

  • Name: Identifier for the installation.

Installation Design Life ​

TODO

Defines the operational period of the engine.

  • Installation Date: Date installation is complete.
  • Decommission date (Optional): Date after which the installation is unavailable.
  • Design Life (Optional): Number of years from installation date the installation will be available.

An installation date is required. If neither decommission date nor design life are present, the engine is considered installed until the end of the simulation.

Engine details ​

TODO

  • Engine Model: Select the engine from the drop-down menu.
  • Engine Quantity: The number of engines. Engines are treated as being in parallel, load distributed equally, maintenance applies to all at once.

Running Properties ​

TODO

  • Fuel type: BG0 (Bio-Gas 100%) , BG20 (Bio-Gas 80%), BG40 (Bio-Gas 60%), BG50 (Bio-Gas 50%).
  • CHP Efficiency: Total efficiency of the CHP system (heat potential heat recovered​). Usually over 90%.

Set Points ​

TODO

  • Lower Set point: Engines stop below this percentage of total capacity.
  • Upper Set Point: Engines stop above this percentage of total capacity.
  • Export Set Point (Optional): If enabled, installation never drops below this set point; excess is exported.
  • Controller Sync offset Set Point (Optional): Required if "Controller Sync" is enabled, for percentage of total output to energize alternators.

Operational Times and Maintenance ​

TODO

  • Operational Times can be used to define the times when an installation is active.
  • Maintenance is used to create shutdown periods to maintain assets or automatic costs based on the amount of hours an installation has run. These are explained in more detail in the Operational Times and Maintenance Section after Modules.
