Three-Phase Parallel RLC Branch - Implement three-phase parallel RLC branch

Library

Elements

Description

The Three-Phase Parallel RLC Branch block implements three balanced branches consisting each of a resistor, an inductor, a capacitor, or a parallel combination of these. Use the Branch type parameter to select elements you want to include in each branch. If you eliminate either the resistance, inductance, or capacitance of each branch, the R, L, and C values are automatically set respectively to infinity (inf), infinity (inf), and 0 and the corresponding parameters no longer appear in the block dialog box. Only existing elements are displayed in the block icon.

Negative values are allowed for resistance, inductance, and capacitance.

Dialog Box and Parameters

Branch type

Select the elements you want to include in the branch. The R letter defines the resistor, the L letter defines the inductor, and the C letter defines the capacitor. Select Open circuit to define an open circuit (R=inf, L=inf, C=0).

Resistance R

The branch resistances, in ohms (Ω).

Inductance L

The branch inductances, in henries (H).

Capacitance C

The branch capacitances, in farads (F).

Measurements

Select Branch voltages to measure the three voltages across the Three-Phase Parallel RLC Branch block terminals.

Select Branch currents to measure the three total currents (sum of R, L, C currents) flowing through the Three-Phase Parallel RLC Branch block.

Select Branch voltages and currents to measure the three voltages and the three currents of the Three-Phase Parallel RLC Branch block.

Place a Multimeter block in your model to display the selected measurements during the simulation. In the Available Measurements list box of the Multimeter block, the measurements are identified by a label followed by the block name.

Measurement	Label
Branch voltages of phases A, B, and C	Ua: , Ub: , Uc:
Branch currents of phases A, B, and C	Ia: , Ib: , Ic:
