IEEE 1547a:2020

Amendment Standard - Active.
The performance and functional capability requirements for DER connected with the Area Electric Power Systems (Area EPS) are defined in IEEE Std 1547(TM). This amendment revises the ranges of allowable trip clearing time settings in Table 13 for DERs in abnormal operating performance category III to allow wider ranges that can broaden and simplify the adoption of the standard. In addition, the related informative Figure H.9 is revised accordingly.

This amendment revises the ranges of allowable trip clearing time settings in Table 13 for DERs in abnormal operating performance category III. No changes are expected for the default trip settings in any of the tables and abnormal operating performance categories. Informative figure H.9 will be updated. No other changes of the language in IEEE Std 1547-2018 shall be part of this amendment.
This document provides a uniform standard for the interconnection and interoperability of distributed energy resources with electric power systems. It provides requirements relevant to the interconnection and interoperability performance, operation and testing, and, to safety, maintenance and security considerations.
IEEE Std 1547-2018 defines the performance and functional requirements for DER connected with the Area Electric Power Systems (Area EPS). This amendment to IEEE 1547 would widen the ranges of allowable trip settings to allow wider ranges that may broaden and simplify the adoption of the standard.
