IEC Types and NERC Types

About IEC Types and NERC Types

IEC Types and NERC Types are standards enforced by the International Electrotechnical Commission (IEC) and the North American Electric Reliability Corporation (NERC) respectively for the exchange of information pertaining to wind turbine operation between various stakeholders in the wind power generation business. GAA Wind conforms to these established standards, thereby ensuring that the data is reported in accordance with the prescribed format and procedures.

Details

To incorporate the IEC and NERC standards, GAA Wind uses the following types of records:

  • GAA Wind IEC Types: A record that represents the event description of the operating state of a wind turbine during a particular period in the IEC-61400-26 standard of the IEC.

    The IEC Types subsection in GAA Wind contains the baseline IEC Types records.

  • GAA Wind NERC Types: A record that represents the event description of the operating state of a wind turbine during a particular period in the standard defined by NERC. For more information, refer to the NERC Types documentation.

    The NERC Types subsection in GAA Wind contains the baseline NERC Types records.

  • GAA Wind IEC And NERC Mapping: A record that represents the method by which an event of IEC Type is converted into its equivalent in NERC Type for the purpose of reporting to NERC using the Generating Availability Data System (GADS) Wind Reporting application.

    The Mapping subsection in GAA Wind contains the baseline IEC and NERC Mapping records.

Note: The following details are only applicable to the event data that is imported from the GE Renewables Digital Wind Farm suite:
  • By default, the events that belong to IEC Type are converted to their equivalent in NERC Type.
  • If the IEC-26 category for an event is IU (Information Unavailable), the event can be manually reviewed. APM attempts to convert the event to its equivalent in NERC Type. If an event that belongs to the IU category is not converted to its equivalent in NERC Type, the event is converted to a NERC Type that is equivalent to the next non-IU event in the sequence if the duration of the IU event is less than 10 minutes; else the NERC Type will be blank if the duration of the IU event is greater than or equal to 10 minutes. For example, if there are five events belonging to the IU category and the next event in the sequence is of a non-IU category, with RUTH as NERC Type, the five events that belong to the IU category are mapped to RUTH if the duration of the IU events is less than 10 minutes.

Access an IEC Type

Procedure

  1. Access the GAA Wind Administrator page.
  2. In the IEC Types subsection, in the ID column, select the link in the row that contains the IEC Type that you want to access.

    The Edit IEC Type window appears.

    Note: As needed, you can modify the values in the available fields, and then select to save your changes.
    Note: You cannot modify the ID value of an IEC Type that is used in an IEC and NERC Mapping record, unless you delete the Mapping or modify it such that it is linked to a different IEC Type.

Access a NERC Type

Procedure

  1. Access the GAA Wind Administrator page.
  2. In the Configuration section, select NERC Types.

    A table of NERC Types appears, displaying the following columns:

    • ID
    • Description

  3. In the ID column, select the link in the row that contains the NERC Type that you want to access.

    The Edit NERC Type window appears.

    Note: As needed, you can modify the values in the available fields, and then select to save your changes.
    Note: You cannot modify the ID value of a NERC Type that is used in an IEC and NERC Mapping record, unless you delete the mapping or modify it such that it is linked to a different NERC Type.

Access a Mapping

Procedure

  1. Access the GAA Wind Administrator page.
  2. In the Configuration section, select Mapping.

    A table of IEC and NERC Mapping records appears, displaying the following columns:
