Argentina (CAMMESA PT-4) — ride-through requirements

The FRT envelope a grid-scale battery must meet under Argentina (CAMMESA PT-4), digitized breakpoint by breakpoint and checked against the clause it came from.

By Sergey Syrvachev — Director of Product Engineering at HyperStrong

Applies to: transmission connections — ERNC parks / generators joining the MEM-SADI grid.

Part of: the grid-code ride-through chart — compare this against 65 other standards in 44 countries.

What this is, and is not. A reading aid compiled from the clause cited below — not a compliance document. The primary text governs. Every value here was read from a current primary source.

Breakpoints

Times are seconds from the start of the disturbance. Voltage is per-unit of nominal; frequency in hertz. An LVRT curve is a lower boundary (stay connected while voltage is on or above it), an HVRT curve an upper boundary, and FRT gives the band between its High and Low boundaries. These are the boundaries, not the behaviour: what holding one demands of the converter — reactive current injection, thermal stress, protection timing — is stepped through in the LVRT / HVRT ride-through visual.

Where these values come from

  • FRTCAMMESA, LOS PROCEDIMIENTOS – P.T.4, numeral 2.2.3.2 lit. b) 'Rangos de frecuencia admisibles de operación' (Pág. 6) + 'Curva límite frecuencia-tiempo / Zona Admisible' (Pág. 7); applied to ERNC parks by ANEXO I numeral 9.8.5. Versión 03-Oct-2023.

Any event not in the table above is not plotted for this code. Where an absence is itself the finding — a code that defines no high-voltage envelope, or one whose curves circulate under another country's name — it is recorded in the grid codes with no ride-through curve.
