PV Curves: Limit Violations
The Limit violations tab is found on the PV Curves dialog and allows the definition of what should be
considered a violation of a monitored voltage. It also provides specification of parameters that will
force the PV process to stop if voltages become inadequate. When choosing to report limit violations in
the PV Curve Tool, if no limit violations are found then the minimum voltage is reported instead.
Identify bus voltages with...
These options will store monitored bus voltages that violate either their high or low voltage limit as
of the last successful solution for each scenario. Only those buses that are set to be monitored
based on the Limit Monitoring Settings will be monitored, and the low and high voltage limits for
each bus are also determined by the limit monitoring settings.
Low Voltage Violations - check this box to store the buses that have low voltage violations
High Voltage Violations - check this box to store the buses that have high voltage violations
Limit Group Definitions - click this button to open the Limiting Monitoring Settings dialog
When choosing to identify limit violations, the Overview table on the PV Results tab will contain
information about the number of violations (#Viol), worst voltage violation (Worst V Viol), and bus
at which the worst voltage violation occurs (Worst V Bus). Also, for any scenario in which a violation
occurs, the Show Violations option is enabled on the local right-click menu of the Overview table.
Choosing this option will open a table detailing all of the violations.
