Permute phases of three-phase system
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.
|Side 1 Phase||Connects to Side 2 Phase|
~123 — Expandable three-phase port
Expandable composite (a1,b1, c1) three-phase port.
~231 — Expandable three-phase port
Expandable composite (a2,b2, c2) three-phase port.
Modeling option — Whether to model composite or expanded three-phase ports
Composite three-phase ports (default) |
Expanded three-phase ports
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.
