modelDeltaLoad_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.
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 powers consumed between phases are kept constant throughout 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.
