modelBaseImpedance
Extends from Buildings.Electrical.Interfaces.PartialPluggableUnbalanced (Partial interface for unbalanced loads).
Information
This model represents a partial interface for a three-phase AC unbalanced impedance.
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
D 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.
