Connector used for modular CHP models
Extends from Modelica.Icons.SignalBus (Icon for signal bus).
Information
This connector is a base connector used forcombined heat and power units and contains typical variables that may be measured in the modular Chp models.
Typically, a Chp unit consists of three main components: Combustion engine, a exhaust heat exchanger and a generator. The controlled parameters are listed below.
