modelDeltaDynLoad_3Ph
Extends from ThreePhaseComponent (Partial model for inheritance of single-phase base power based on three-phase system base power.).
Information
This is a three-phase delta load model that allows the user to vary the power consumed during the simulation.
The user needs to input the active (P_ab, P_bc and P_ca) and reactive (Q_ab, Q_bc and Q_ca) powers consumed between phases. Since the values come from independent parameters, the model allows the representation of unbalanced loads.
In addition, the model allows the load to be represented as constant power, or as a ZIP model. In the first approach, the load consumes the same value of active and reactive powers between phases throughout the simulation. The latter approach allows the load to be represented as a sum of three terms: constant impedance, constant current and constant power. This means that, depending on voltage levels supplied, the load will consume different values of power.
In addition to that, the real input DynFact multiplies the power being consumed by the load. This allows the load to vary over time during the simulation. It is also important to note that DynFact multiplies all variables P_ab, P_bc, P_ca, Q_ab, Q_bc and Q_ca. That means that this model does not allow load variation to be performed only in selected variables.
