Panama (Código de Redes Fotovoltaico 2017) ride-through requirements

Low-voltage ride-through, High-voltage ride-through, Frequency ride-through for Panama. Every breakpoint below is read from the code itself, and where a point was taken off a published figure rather than stated in the clause, the section under that chart says so — an envelope that stops where its published chart stops or an envelope the source only partly defines.

What is the low-voltage ride-through envelope for Panama (Código de Redes Fotovoltaico 2017)?

The plant must ride through for any voltage that stays on or above this envelope. The envelope holds 0 pu from t = 0 to 150 ms; then ramps linearly from 0 pu at 150 ms to 0.9 pu at 2.2 s; then 0.9 pu from 2.2 s, plotted to 7 s.

The clause states this boundary as a line; intermediate points are interpolated between its stated vertices. The envelope stops where the published chart stops; the code states no end time.

What is the high-voltage ride-through envelope for Panama (Código de Redes Fotovoltaico 2017)?

The plant must ride through for any voltage that stays on or below this envelope. The envelope holds 1.2 pu from t = 0 to 2.2 s; then 1.1 pu from 2.2 s onward — the last band the envelope defines, with no stated end time.

What is the frequency ride-through envelope for Panama (Código de Redes Fotovoltaico 2017)?

The plant must ride through between the upper and lower bands. The upper (over-frequency) band holds 61.7 Hz from t = 0 to 30 s; then 61.5 Hz from 30 s to 3 min; then 60.5 Hz from 3 min onward — the last band the envelope defines, with no stated end time.

Scope

Who does Panama (Código de Redes Fotovoltaico 2017) bind, and since when?

PV plants connected to the national interconnected system (SIN). No date of effect is published here — grid codes are reissued, so check the current issue before relying on it.

These figures are a reading aid, not legal advice. Grid codes are reissued: verify against the current edition before you design to them.

Digitised operating parameters beyond ride-through — droop, reactive capability, operating ranges — are published for 36 of the 66 codes in this atlas, not yet for Panama (Código de Redes Fotovoltaico 2017). That is a gap on this site, not a statement that Panama (Código de Redes Fotovoltaico 2017) sets none — the atlas hub marks the codes that carry them.

Curve data last checked against the code on — 66 standards, 130 envelopes, published by bess.engineer under CC BY 4.0.

Questions

Questions this page answers about Panama (Código de Redes Fotovoltaico 2017)

Does Panama (Código de Redes Fotovoltaico 2017) require ride-through, or only that the plant does not trip?
Ride-through. Every envelope on this page is a performance duty the plant must meet, not a protection-setting no-trip boundary — they are different obligations. That is what these curves are; they are not everything Panama (Código de Redes Fotovoltaico 2017) contains. The requirement sentence under each chart says which side of the curve is the compliant one.
Are the numbers on this page taken from Panama (Código de Redes Fotovoltaico 2017) itself?
Every breakpoint is read from the code, and where a point was taken off a published figure rather than stated in the clause, the section under that chart says so — on this page that includes an envelope that stops where its published chart stops or an envelope the source only partly defines. The clause each curve came from is quoted under it.
Which events are charted for Panama (Código de Redes Fotovoltaico 2017)?
Panama (Código de Redes Fotovoltaico 2017) is charted here with 3 envelopes — low-voltage ride-through, high-voltage ride-through, frequency ride-through (LVRT, HVRT, FRT).

Ride-through, in context.

An envelope is a compliance boundary; understanding why it exists is a different question. The ride-through and grid-forming entries cover the engineering, and the Engineering Foundations course builds it from the physics up.
