Neutral Port (Three-Phase)
Connect phases of three-phase system to electrical conserving port
Simscape / Electrical / Connectors & References
The Neutral Port (Three-Phase) block connects the phases of a three-phase system to an electrical conserving port.
If you do not need to connect the neutral port to other blocks, use a Floating Neutral (Three-Phase) block instead. If you want to ground the neutral port, use a Grounded Neutral (Three-Phase) block.
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.
Parasitic ground conductance — Parasitic ground conductance
Parasitic conductance to ground. A nonzero value is required for the simulation of some circuit topologies.
