Modelica.Electrical.MultiPhase.Interfaces.Plug

Information

Connectors PositivePlug and NegativePlug are nearly identical. The only difference is that the icons are different in order to identify more easily the plugs of a component. Usually, connector PositivePlug is used for the positive and connector NegativePlug for the negative plug of an electrical component.
Connector Plug is a composite connector containing m Pins (Modelica.Electrical.Analog.Interfaces.Pin).

Modelica.Electrical.MultiPhase.Interfaces.ConditionalHeatPort

Information

This partial model provides conditional heat ports for the connection to a thermal network.

• If useHeatPort is set to false (default), no heat port is available, and the thermal loss power flows internally to the ground. In this case, the parameter T specifies the fixed device temperatures.
.
• If useHeatPort is set to true, all heat ports are available.

Parameters

Type	Name	Default	Description
Integer	mh	3	Number of heatPorts=number of phases
Boolean	useHeatPort	false	=true, if all HeatPorts are enabled
Temperature	T[mh]	fill(293.15, mh)	Fixed device temperatures if useHeatPort = false [K]
