Data record `tests.relay-81-frequency-test.ieee2800.frequency-protection`

Verified 2026-10-24 Confidence: High

Clause 9.1 of IEEE 2800-2022 does not require frequency protection on an inverter-based resource plant; where a frequency element is applied it must allow the frequency ride-through of clause 7.3.2 and be coordinated with the transmission system's underfrequency load shedding.

Provenance. Where this record comes from and where it is used: the cited source, the record itself and the entry that cites it.

Provenance: the chain from source to entry.
