Nomogram Display

The Nomogram Display is used to modify and create Nomogram definitions. Nomograms are combinations of two interfaces for monitoring combined flows on the interfaces concurrently. These Nomogram interfaces will have a limit definition that defines a region of allowed flow on the interfaces, and can be monitored in many tools in Simulator as potential constraints, such as the contingency analysis reporting of interface violations. Another major potential use for nomograms is in the Optimal Power Flow solution to monitor the flow on a pair of interfaces. Nomogram information can also be extremely useful for summarizing the flows on a pair of interfaces whose operation and allowed flow are closely tied together. Nomogram flows can be monitored using the Limit Monitoring Settings Display.

The Nomogram Display presents more detailed information for each nomogram that has been defined for the case. The Nomogram Display is a class of Case Information Display and therefore can be used in a manner consistent with all other case information displays. It has a local menu from which you can print, copy, and modify its information as well as view the information dialog of its associated nomograms.

You can sort the nomogram information by clicking on the heading of the field by which you want to sort. Additionally, you can choose to restrict the information shown by the Interface Display according to the constraints of the area/zone/owner filters.

To show the interface display, select Aggregations > Nomograms in the Model Explorer.

Nomogram information can be saved in the "*.aux" auxiliary file format. See Auxiliary Files for details.

 

The Nomogram display contains the following fields:

Name

Alphanumeric identifier for the nomogram.

Int A Flow

Current MW flow on the first interface of the interface pair forming the nomogram. This flow is the sum total of the Base MW Flow and the Contingent MW Flow.

Int B Flow

Current MW flow on the second interface of the interface pair forming the nomogram. This flow is the sum total of the Base MW Flow and the Contingent MW Flow.

% Limit, Max Nomo-interface

The actual MW flow on the nomogram as a percentage of the combined nomogram limit.

Monitor

Indicates whether or not the nomogram should be monitored either for violations or as a constraint in the Optimal Power Flow.

Limit Group

The name of the limit group the nomogram is a member of for limit monitoring.
