Events

About IEC Events

IEC Events are standardized classifications of the operating state of a wind turbine. They are based on the IEC-61400-26 standard of the International Electrotechnical Commission (IEC).

IEC Events are determined from an analysis of the raw event data of wind turbines over time. They are used to determine the key metrics in a Performance Report.

IEC Events are stored in the GAA Wind Event records. You can associate IEC Events with any wind turbine regardless of its manufacturer.

Import Events

Before You Begin

Procedure

  1. Access the GAA Wind Overview page.
  2. Select Import IEC Events.
    The Imported Events page appears, displaying a table of log files associated with the imported Events.

    Note: Depending on the state of the job, the log files appear in the In progress, Successful or Failed section.
  3. Select Import IEC Events.

    The Import Event window appears, displaying the Import Details section.



  4. In the Company box, select the Company for which you want to import the Events.
  5. In the Sub Group box, select the Sub Groups for which you want to import the Events.
  6. In the Start Date box, select the start date of the period for which you want to import the Events.
    Important: When importing Events, the value in this box is treated as a Coordinated Universal Time (UTC) value to ensure accuracy in the count of Events imported for a given period, regardless of your time zone.
  7. In the End Date box, select the end date of the period for which you want to import the Events.
    Important:
    • When importing Events, the value in this box is treated as a UTC value to ensure accuracy in the count of Events imported for a given period, regardless of your time zone.
    • The error code value of an Event may change depending on the values in the Start Date and End Date boxes (that is, the duration for which you are importing Events).
    Note: You cannot import Events if the difference between the values in the Start Date and End Date boxes is greater than 31.
  8. Select Next.

    The Import Validation section appears, displaying the fields that are described in the following table.

    Field NameDescription
    SUB GROUP NAMEThe name of the Sub Group for which you want to import the Events.
    PREVIOUSLY IMPORTED EVENTSThe total count of Events that were previously imported for the selected Sub Group, and the date range for which the data is displayed.
    MANUALLY CREATED EVENTSThe total count of Events that were manually created for the selected Sub Group, and the date range for which the data is displayed.
    EDITED EVENTSThe total count of Events that have been edited for the selected Sub Group, and the date range for which the data is displayed.
    TOTAL EVENTSThe total count of Events, which is the sum of previously imported and manually created Events for the selected Sub Group, and the date range for which the data is displayed.


  9. Select the check box next to the following text: I understand that by clicking 'Finish' I will overwrite the above shown events.

    The Finish button is enabled.

  10. Select Finish to start the import.

Results

  • In the Imported Events page, a row containing the log file associated with the Events being imported is added to the table under the In Progress, Successful or Failed section for each Sub Group after the import job starts. The table contains the following columns:

    • ID: Contains an identifier for the Events.
    • LOG: Contains the log file associated with the Events.
    • STATUS: Contains one of the following values for each row:
      • Staging: Indicates that the data import job is preparing to load the Events into GE Digital APM.
      • In Progress: Indicates that the data import job is loading the Events into GE Digital APM.
      • Submitted for Cancellation: Indicates that the data import job has been submitted for cancellation.
      • Completed: Indicates that the data import job has loaded the Events into GE Digital APM.
      • Completed With Errors: Indicates that the data import job is completed, but it has encountered one or more errors.
        Note: The data import job may be completed with errors when it exceeds the time that is specified in the Import Job Time (Minutes) box when configuring settings. You can download the log file to access the error messages.
      • Aborted: Indicates that the data import job is aborted either because it is cancelled or because a scheduled job for the Sub Group is running.
    • CANCEL: This column appears only in the In Progress section. You can select to cancel a job whose status is Staging or stalled beyond the timeout period.
    • START DATE: Contains the start date that you entered in the Import Event window.
    • END DATE: Contains the end date that you entered in the Import Event window.
    • IU TIME PERCENTAGE: Contains the percentage of the total IU time for the Events, as a function of the total report time.
      Note:
      • The total IU time is the sum duration of the IU Events (that is, Events that have the value IU in the IEC Event Type field).
      • The total report time is the duration for which you are attempting to import the Events (that is, the duration specified in the Import Event window).
    • AGGREGATED ERROR CODE: Contains a two-digit bit-mapped code. 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.
    • DATA QUALITY PARAMETERS: Contains a link that, when selected, displays the Data Quality Parameters window.
    • RECEIVED RECORDS: Contains the count of received Events.
    • INSERTED RECORDS: Contains the count of inserted Events.
    • DELETED RECORDS: Contains the count of deleted Events.
    • STARTED BY: Contains the name of the user who started the import job. For scheduled jobs, the value in the column will be MIJOB.
    • LAST UPDATED DATE: Contains the date and time when the import job was started.
    • TERMINATED BY: Contains the name of the user who cancelled the import job.
    • TERMINATED DATE: Contains the date and time when the imported job was cancelled.
  • If an Event that is being imported already exists in GE Digital APM, it is replaced.

Create Events

About This Task

For a Unit in a Sub Group, if the imported Events have a gap in time, you can create one or more Events for the missing period in the Events workspace in the Sub Group Summary page. This topic describes how to create Events.
Note: For a Unit, the Events are considered to have a gap in time when:
  • For a given period, if the value in the Start Date field of an Event is different from that in the End Date field of the previous Event.
    Note: The period is identified by the values that are specified in the From and To boxes in the Filter By Date Range window.
  • If the imported Events do not account for the complete duration of the period.
    Note: If the start time stamp of an Event is earlier than the start date and time of the specified period, or if the end time stamp of an Event is later than the end date and time of the specified period, the Event does not appear in the Events workspace. Instead, a highlighted row may appear in the Events workspace to indicate that the Event is missing. You can ignore such a row because it is not considered a missing Event.

Before You Begin

  • Confirm that the Events imported for a Unit in a Sub Group have a gap in time.

Procedure

  1. Access the Sub Group Summary page.
    Tip: In the Events workspace, the missing Event is represented by a highlighted row. By default, the Start Date and End Date columns in this row are populated with values that account for the gap in time.
  2. In the Events workspace, select the check box next to the row that represents the missing Event that you want to create.
  3. Select .

    The Create Event window appears.

  4. As needed, enter values in the available fields.
    Tip: In the Create Event window, in the Number Of Events box, enter the number of Events that you want to create. The value that you enter determines the number of rows (that is, the number of Events) that appear in the window.
    Note:
    • In the Create Event window, the start date and the end date of the missing period appear in the Original Start Date box and the Original End Date box respectively.
    • The missing period is evenly split based on the number of Events you want to create. The start date and the end date of each split period appear in the Start Date column and the End Date column of each row. You can modify the values in these columns; however, the value in the Start Date column of any row cannot be less than that in the Original Start Date box, and the value in the End Date column of any row cannot be greater than that in the Original End Date box. In addition, all the new Events in the window must account for the missing period.
  5. Select Create.
    In the Events workspace, the rows that contain the Events you have attempted to create are highlighted.
    Note: To discard your changes, select .
  6. Select .

  5. As needed, enter values in the remaining fields.
    Note:
    • In the Split Event window, the start date and the end date of the existing Event appear in the Original Start Date box and the Original End Date box, respectively.
    • The period of the existing Event is evenly split based on the number of Events to which you want to split the Event. The start date and the end date of each split period appear in the Start Date column and the End Date column of each row, respectively. You can modify the values in these columns; however, the value in the Start Date column of any row cannot be less than that in the Original Start Date box, and the value in the End Date column of any row cannot be greater than that in the Original End Date box. In addition, the sum duration of the split Events in the window must be same as the period of the existing Event.
    • The actual production of the existing Event (that is, the value in the Original Actual Production box) is evenly split based on the number of Events to which you want to split the Event. You can modify the value. A warning message appears, if the sum of actual production of the split Events in the window is not same as the actual production of the existing Event.
