Information

This model represents a partial interface for a three-phase AC unbalanced impedance with a neutral cable. The current in the neutral cable is computed as the algebraic sum of the currents in the loads.

The model can be configured in order to represent different type of impedances as well as configurations.

The loads can be connected either in wye (Y) or delta (D) configuration. The parameter loadConn can be used for such a purpose.

The model has three impedances that can be either connected in Y or Delta configuration. The parameter loadConn can be used for such a purpose. The Boolean parameter inductive can be selected to specify the type of impedance.

The impedances on each phase can be removed using the boolean flags plugPhase1, plugPhase2, and plugPhase3. These parameters can be used to generate unbalanced loads.

The values of the impedances are computed starting from the parameters R, L, and C. Depending on the values of the boolean flag inductive some of these parameters may be disabled. There are additional flags use_R_in, use_L_in, and use_C_in that can be used to specify time varying impedances.
