Event Records

Event records store information about the fields that are defined for the Primary Event and Contributing Event families in the baseline GE Digital APM database. This topic provides an alphabetical list and description of the fields that exist for the Primary Event and Contributing Event families and appear on the Event datasheet. The information in the table reflects the baseline state and behavior of these fields. The values in these fields are defined by NERC in the GADS DRI and CEA in the Generation Equipment Status ERIS. This list is not comprehensive.

This family is enabled for site filtering, which means that records in this family can be assigned to a specific site, and will then only be accessible to users who are assigned to the same site and have the appropriate license and family privileges. See the Site Filtering section of the documentation for more information on using this feature.

This field is only enabled for Reserve Shutdown events. This field contains a value that is calculated depending on the value contained in the Capacity Event Type field. If the value in the Capacity Event Type field contains a value that identifies the event as:
- A derate event, this field will become required, and the value must be less than the value in the Net Dependable Capacity field. This field is cleared and becomes required when the Net Derate Amount field contains no value or the value 0 (zero). If the Net Derate Amount field contains a value, this field will be populated automatically using the following formula:
  Net Dependable Capacity - Net Derate Amount
- An outage event, this field will become disabled and populated with the value 0 (zero).
For a Contributing Event, this field is disabled and populated automatically with the value in the Net Available Capacity field in the GAA Unit that contains a value in the Unit ID field that matches the value in the Unit ID field in the Event.

Net Dependable Capacity

Character

Identifies the net dependable generation capacity of the unit at which the event occurred.

This field is populated automatically with the value in the Net Dependable Capacity field in the Unit Capacity record for a GAA Unit based on the start date of the Primary Event.

This field exists in the Primary Event family but not the Contributing Event family.

Net Derate Amount

Character

Indicates the net amount of generation capacity that was lost during the event.

This field is only enabled for Derate events. This value is used to calculate the value in the Net Available Capacity field. The default value is 0 (zero). If the value in the Capacity Event Type field contains a value that identifies the event as:
- A derate event, this field is an optional field. If this field contains a value other than 0 (zero), the value in the Net Available Capacity field will be disabled and populated automatically using the following formula:
  Net Dependable Capacity - Net Derate Amount
  If this field contains no value or the value 0 (zero), the Net Available Capacity field is cleared and becomes required.
- An outage event, this field will become disabled and populated with the value 0 (zero).
For a Contributing Event, this field is disabled and populated automatically with the value in the Net Derate Amount field in the GAA Unit that contains a value in the Unit ID field that matches the value in the Unit ID field in the Event.

Net Maximum Capacity

Character

Identifies the net maximum generation capacity of the unit at which the event occurred.

This field is populated automatically with the value in the Net Maximum Capacity field in the Unit Capacity record for a GAA Unit based on the start date of the Primary Event.

True, the event is considered outside of management control.
False, the event is considered to be within management control.

Potential Capacity Incident Cost

Character

Identifies the potential cost of the event.

This field is disabled and populated automatically with the calculated event cost, if a cost has been calculated.

This field exists in the Primary Event family but not in the Contributing Event family.

Primary Incident ID

Character

Identifies the Primary Event for which the Contributing Event exists.

This field is disabled and populated automatically with the value in the Event ID field in the Primary Event to which the Contributing Event is linked.

This field exists in the Contributing Event family but not the Primary Event family.

Problem Alert

Boolean

Indicates whether the problem that caused the event is the result of a design flaw or standard operating practices.

If the value in this field is:

True, the problem was the result of a design flaw or standard operating practices.
False, the problem was the result of another cause.

Refresh Incident Cost

Boolean

Indicates whether the GE Digital APM system should refresh the cost calculation for the Primary Event.

When you save the Primary Event, if the value in this field is:

True, the GE Digital APM system will update the value in the Capacity Incident Cost field and then save the new value, along with any other changes that you made the Primary Event.
False, the GE Digital APM system will save any changes that you made to the Primary Event but will not update the value in the Capacity Incident Cost field.

This field exists in the Primary Event family but not the Contributing Event family.

Reporting Month

Character

Identifies the month for which the data in the Primary Event should be reported.

This field is disabled and populated automatically with the month indicated by the value in the Event Start Date field.

This field exists in the Primary Event family but not the Contributing Event family.

Reporting Year

Numeric

Identifies the year for which the data in the Primary Event should be reported.

This field is disabled and populated automatically with the year indicated by the value in the Event Start Date field.

This field exists in the Primary Event family but not the Contributing Event family.

Revision

Numeric

Identifies the revision number of the Event and should be incremented each time you re-submit a report which includes information in the Event to a Regulatory Organization.

By default, for an Event submitted to the regulatory organization for the first time, the value in this field is set to 0.

You must increase the value in this field each time you submit a report to the Regulatory Organization.

Start Date is Estimated?

Boolean

Indicates whether the value in the Event Start Date field is an estimate.

Select this check box when the value in the Event Start Date field represents an estimate of when the event ended or will end.

Clear this check box if the value in the Event Start Date field represents the actual time that the event ended.

This field exists in the Primary Event family but not the Contributing Event family.

Trip Mechanism

Character

Indicates how the unit was shut down during the event.

This field contains no value by default, and a baseline rule exists to populate this field with a list of the following values:

A - Automatic: The unit shut down automatically.
M - Manual: The unit was shut down manual by an operator.

After you select a value in this field and save the Event record, you will not be able to clear the field.

This field is available in the Additional Reporting section for a Primary Event.

Unit ID

Character

Identifies the Unit ID of the GAA Unit record with which the Event is associated.

For a Primary Event, a baseline rule exists to populate this field with a list of values from the Unit ID and Unit Name fields in all GAA Unit records that you have permission to modify using the formula Unit ID (Unit Name).

This field is required when the Primary Event is in the Unit Approved state.
For a Contributing Event, this field is disabled and populated automatically with the value in the Unit ID field in the Primary Event for which the Contributing Event exists.

Unit Name

Character

Identifies the name of the unit to which the event occurred.

This field is disabled and populated automatically using values from Performance or GAA Unit records.

Validate Incident

Boolean

Indicates whether the GE Digital APM system will validate the record against all other existing Primary Events.

When you save the Primary Event, if the value in this field is:

True, the GE Digital APM system will check all other Primary Events to validate any sequential event pairs of which the Primary Event is a part, update the value in the Incident Validation Status field if necessary, and then save the Primary Event to the database.
False, the GE Digital APM system will save any changes that you made to the record, but will not validate the Primary Event against any other Primary Events.

This field exists in the Primary Event family but not the Contributing Event family.

Verbal Description

Character

Describes the event.

This field can be used to store any information about the event that is not captured in the other fields in the Event record.

When you create a Primary Event, you can enter a verbal description of up to 255 characters. When you generate a NERC Event Report, the verbal description in the generated report will display only the first 84 characters of the description that you entered in the Verbal Description field.

This field is required when the Primary Event is in Unit Approved state.
