Description

The Three-Phase Series RLC Branch block implements three balanced branches consisting each of a resistor, an inductor, or a capacitor or a series combination of these. Use the Branch type parameter to select elements you want to include in each branch.

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

Parameters

To edit block parameters interactively, use the Property Inspector. From the Simulink^® Toolstrip, on the Simulation tab, in the Prepare gallery, select Property Inspector.

Branch type — Elements to include in branch

RLC (default) | R | L | C | RL | RC | LC | Open circuit

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=0, L=0, C=inf). Only existing elements are displayed in the block icon.

Resistance R (Ohms) — Branch resistances

1 (default) | scalar

Branch resistances, in ohms (Ω).

Inductance L (H) — Branch inductances

1e-3 (default) | scalar

Branch inductances, in henries (H).

Capacitance C (F) — Branch capacitances

1e-6 (default) | scalar

Branch capacitances, in farads (F).

Measurements — Block measurements

None (default) | Branch voltages | Branch currents | Branch voltages and currents

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

Select Branch currents to measure the three currents flowing through the Three-Phase Series RLC Branch block.

Select Branch voltages and currents to measure the three voltages and the three currents of the Three-Phase Series 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.
