connectorApparentPowerPort

Single phase electric connector containing active and reactive power and frequency and voltage for quasistationary ac power models

Extends from ActivePowerPort (General interface for electrical energy in TransiEnt library (Active power and frequency)).

Information

1. Purpose of model

Adds nothing but a symbol to the model TransiEnt.Base.Interfaces.Electrical.PartialElectricPowerPort

2. Level of detail, physical effects considered, and physical insight

The connector contains the transmitted reactive and active power, voltage and frequency. The frequency is always assumed to be ideally sinusoidal without harmonic components. Unsymmetric electric grids may be modelled by using three instances of this connector.

An example how to adapt models based on Modelica.Electrical.Analog.Interfaces.Pin can be found here: AdaptionOfComplexElectricLoad

An adaption to simple real values can be realized using an adapter block like PQ_To_EPP or a boundary component PrescribedPotentialVariableBoundary

3. Limits of validity

(Purely technical component without physical modeling.)

4. Interfaces

(no remarks)

5. Nomenclature

f is the frequency of alternating current

v is the voltage

P is the active power

Q is the reactive power

6. Governing Equations
