.TransiEnt.Producer.Combined.LargeScaleCHP.Base.PartialCHP

Information

1. Purpose of model

This partial model offers a template for the creation of large scale CHP models with condensation-extraction configuration.

The main elements of this partial model are:

Set-value interfaces: these consist of one set value for the power production and one set value for the heat production and according to the library's sign and units convention.
Local sensors (statistics): these consist of power and heat collectors, as well as emissions and cost collectors.
Output interfaces: these consit of one electric power interface and two fluid port interfaces (district heating return and supply).
Plant's operation limits: these limits are given in form of PQ diagramms (see component TransiEnt.Producer.Combined.LargeScaleCHPpackage.Base.pQDiagram) as well as Max and Min operators.
Plant's heat input calculation: this calculation is based on an externally calculated characteristic field (see component TransiEnt.Distribution.Heat.HeatGridControl.Q_flow_set_SG).

This partial model is used in components such as:
