Description

The Phase Splitter block expands a composite three-phase port into its constituent phases.

The expanded output ports are electrical conserving ports.

Model Examples

Comparison of Three-Phase Port Types

A comparison of Composite three-phase ports versus Expanded three-phase ports. The first circuit shows a Voltage Source configured with a Composite three-phase port. A Phase Splitter block provides the interface to the Simscape™ foundation library electrical elements. The second circuit shows a Voltage Source configured with an Expanded three-phase port which can connect directly to the Simscape foundation library electrical elements. The Voltage Source can be changed from Composite to Expanded three-phase ports by use of the Simscape block choices option on the right-click context menu.

AC Cable with Bonded Sheaths

A three-phase cable model comprised of multiple pi-sections. Each phase is enclosed in a conductive sheath. The conductive sheath is connected to ground at either end of the cable through a simple resistance. A high-voltage source provides power to an unbalanced resistive load through the power cable. You can configure the sheath to be either series-bonded or cross-bonded. You can also configure the number of pi-sections. Increasing the number of pi-sections improves the accuracy but slows down the simulation. To facilitate convergence, the voltage source includes an internal impedance.
