ATR Document Review
To improve overall performance and therefore reliability of the AUFLS scheme, the System Operator and NI AUFLS providers will be moving to a 4-block AUFLS scheme.
The ATR Document details the performance and compliance requirements of a 4-block AUFLS scheme to be connected to the power system in the North Island to meet the Code obligations set out in Part 8, Technical Code B – Emergencies. By meeting these obligations, the System Operator can plan to comply, and to comply with its Principal Performance Obligations.
The ATR will provide clarity of:
- Technical guidance and requirements to assist NI AUFLS providers with their AUFLS scheme designs;
- Relay settings and performance requirements;
- When yearly feeder data information should be submitted to the System Operator; and
- Data requirements post-AUFLS activation
The ATR Document will be incorporated into the Code by reference alongside the Technical Code B requirements for a 2-block scheme.
As a result of the consultation completed by the Electricity Authority in April 2021, the System Operator has updated the ATR document to provide further clarity on the technical requirements for a 4-block scheme. No substantive changes were identified to be included in the ATR document.
