Permute phases of three-phase system

  • Phase Permute block

Simscape / Electrical / Connectors & References


The Phase Permute block cyclically permutes (changes the order of) the phases of a three-phase system.

The block has two three-phase connections associated with its terminals. If you consider the side of the block labeled ~123 (a1,b1, c1 in expanded view) as side 1 and the side of the block labeled ~231 (a2,b2, c2) as side 2, then the block connects phases as shown in the table.

Whether to model composite or expanded three-phase ports.

Composite three-phase ports represent three individual electrical conserving ports with a single block port. You can use composite three-phase ports to build models that correspond to single-line diagrams of three-phase electrical systems.

Expanded three-phase ports represent the individual phases of a three-phase system using three separate electrical conserving ports.
