The Data Quality Parameters Window

The Data Quality Parameters window appears when you select the link in the Data Quality Parameters column in the GAA Wind Event Import page. It contains the following information pertaining to the Events for the Sub Group and the period you selected in the Import Event window:

Error Event Percentage: The percentage of Events that contain an error, as a function of the total Events.
For example, if there are 100 Events out of which 20 have an error, the Error Event Percentage is 20%.
This data provides information about how many Events that are used for reporting contains errors.
Total Report Time: The duration for which you are importing the Events, in minutes.
IU Time Percentage: The percentage of the total IU time for the Events, as a function of the total report time.
For example, if the total report time is 100 minutes, and the sum duration of the IU Events is 20 minutes, the IU Time Percentage is 20%.
Aggregated Error Code: The two-digit bit-mapped code that indicates the result of the validation performed on the Sub Group. The left bit indicates whether at least one Event existed for each wind turbine per hour. The right bit indicates whether the sum duration of the Events is same as the total report time for the Sub Group. The value 0 in either location indicates that the validation passed, whereas the value 1 indicates that it failed.
Total Events: The total number of Events.
Total Error Events: The total number of Events that contain an error.
Error Time Percentage: The percentage of the total error time for the Events, as a function of the total report time.
For example, if the total report time is 100 minutes, and the sum duration of Events that have an error is 20 minutes, the Error Time Percentage is 20%.
Total IU Time: The sum duration of the IU Events (that is, Events that have the value IU in the IEC Event Type field), in minutes.
Total Error Time: The sum duration of Events that have an error, in minutes.
IU Event Percentage: The percentage of the IU Events, as a function of the total Events.
For example, if there are 100 Events out of which 20 have the value IU in the IEC Event Type field, the IU Event Percentage is 20%.

The Events Workspace and the GAA Wind Edit Events Page

The following table provides a list of tasks that you can perform in:

The Events workspace, which appears in the Sub Group Summary page with a table of Events.
The GAA Wind Edit Events page, which appears when you select Edit Events in the All Events section in the GAA Wind Overview page.

Show Only Edited Events: If you select this check box, only edited Events (that is, Events whose value in the NERC Type field is different from that in the Mapped NERC Type field) appear for the specified period. Important: When filtering Events, the values in the From and To boxes are treated as Coordinated Universal Time (UTC) values to ensure accuracy in the count of Events retrieved for a given period, regardless of your time zone. Note: If the start time stamp of an Event is earlier than the value specified in the From box, the Event does not appear after applying the filter. If the end time stamp of an Event is later than the value specified in the To box, the Event does not appear after applying the filter.
Modify the count of Events that appear in the table in a given page.	The Events workspace and the GAA Wind Edit Events page.

The GAA Wind Edit Events page.
The Events workspace in the Sub Group Summary page.

The error in the error code window is represented by the value 1 in the six-digit bit-mapped code. The following table illustrates what the value 1 in each position of the code represents.
