Unbalanced faults use positive, negative, and zero-sequence networks from the model sequence fields. Generator, inverter, motor/load, transformer grounding, neutral impedance, cable shield grounding, and source sequence values are included where entered; utility/manufacturer sequence data should still be used for final protection studies.

Outage Equipment and Common-Mode Groups

Exclude intentionally radial or non-contingent devices. Equipment sharing a group name is outaged together in common-mode studies.

Rate A is used for the base case. The selected Rate B or C emergency rating is used after an outage. Corrective control movements and disconnected supply are reported separately from numerical convergence.

Adaptive Newton tracing uses the active contingency set's outage eligibility and corrective-control policy. PV traces preserve each stressed load's power factor; QV traces report net MVAr injection relative to the scenario operating point.

The internal RMS solver uses implicit trapezoidal state integration with the positive-sequence network, source swing, load, generator-control, fault, switching, and swing-bus states. It is a model-development tool, not a replacement for executing proprietary PSS/E models.
