OpenIPSL.Electrical.ThreePhase.Loads.WyeLoad_3Ph

Three-phase wye load

Information

This is a three-phase wye load model.

The user needs to input the active (P_a, P_b and P_c) and reactive (Q_a, Q_b and Q_c) powers consumed by each phase. 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 by each phase 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.

Two-phase wye load

Information

This is a two-phase wye load model.

The user needs to input the active (P_a and P_b) and reactive (Q_a and Q_b) powers consumed by each of the two phases. Since the values come from independent parameters, the model allows the representation of unbalanced loads.

Single-phase load

Information

This is a single-phase load model.

The user needs to input the active (P_a) and reactive (Q_a) powers consumed by the phase. 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 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.

OpenIPSL.Electrical.ThreePhase.Loads.WyeDynLoad_3Ph

Variable balanced three-phase wye load

Information

This is a three-phase wye load model that allows the user to vary the power consumed during the simulation.

The user needs to input the active (P_a, P_b and P_c) and reactive (Q_a, Q_b and Q_c) powers consumed by each phase. 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 by each phase 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_a, P_b, P_c, Q_a, Q_b and Q_c. That means that this model does not allow load variation to be performed only in selected variables.

OpenIPSL.Electrical.ThreePhase.Loads.DeltaLoad_3Ph

Three-phase delta load

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.

OpenIPSL.Electrical.ThreePhase.Loads.DeltaLoad_2Ph

Two-phase delta load

Information

This is a two-phase delta load model. The model allows the user to represent active and reactive power being consumed between two phases.

The user needs to input the active (P_ab) and reactive (Q_ab) powera consumed between phases one and two (A and B).

In addition, the model allows the load to be represented as constant power, or as a ZIP model. In the first approach, the power consumed between the two phases is 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 a different power value.

OpenIPSL.Electrical.ThreePhase.Loads.DeltaDynLoad_3Ph

Variable three-phase delta load

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.

OpenIPSL.Electrical.ThreePhase.Loads.Dyn_wye_3Ph_balanced

Variable balanced three-phase wye load

Information

This is a three-phase wye load model that allows the user to vary the power consumed during the simulation.

The user needs to input the entire active (P0) and reactive (Q0) powers consumed by the load. Since the model represents a balanced load, the active and reactive powers consumed by each phase are P0/3 and Q0/3. The model allows the load to be represented as constant power only.

In addition to that, the real inputs P_in and Q_in multiply the values of active and reactive power, respectively, being consumed by the load. This allows the load to vary its consumed power over time during the simulation. Note that, since active and reactive powers can vary independently, the load's power factor can also vary. In addition, note that by changing P0 and Q0, the values of power consumed by the three phases vary identically. This makes the load to be characterized as balanced.

OpenIPSL.Electrical.ThreePhase.Loads.Dyn_wye_3Ph_unbalanced

Variable unbalanced three-phase wye load

Information

This is a three-phase wye load model that allows the user to vary the power consumed during the simulation.

The user needs to input the actives (P0_a, P0_b, and P0_c) and reactives (Q0_a, Q0_b, and Q0_c) powers consumed by each phase of the load. Since the values come from independent parameters, the model allows the representation of unbalanced loads. The model allows the load to be represented as constant power only.

In addition to that, the real inputs P_in and Q_in multiply the values of active and reactive power, respectively. This allows the load to vary its consumed power over time during the simulation. Note that, since active and reactive powers can vary independently, the load's power factor can also vary. In addition, note that, since P_in and Q_in have a 3x1 dimension, P0_a, P0_b, P0_c, Q0_a, Q0_b, and Q0_c can vary idependently. This makes the load to be characterized as unbalanced.
