Saudi Arabia (SAGC) — ride-through requirements
The LVRT, HVRT, FRT envelopes a grid-scale battery must meet under Saudi Arabia (SAGC) (Saudi Arabia), digitized breakpoint by breakpoint and checked against the clause it came from.
Part of: the grid-code ride-through chart — compare this against 63 other standards in 42 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.
| Event | Duty | Breakpoints | Status |
|---|---|---|---|
| low-voltage ride-through (LVRT) | ride-through | 0.001s → 0 pu; 0.3s → 0 pu; 0.301s → 0.13 pu; 0.63s → 0.13 pu; 0.631s → 0.4 pu; 0.97s → 0.4 pu; 0.971s → 0.67 pu; 1.3s → 0.67 pu; 1.301s → 0.9 pu | verified |
| high-voltage ride-through (HVRT) | ride-through | 0.001s → 1.2 pu; 1s → 1.2 pu; 1.001s → 1.1 pu | verified |
| frequency ride-through (FRT) | ride-through | High: 0.1s → 62.5 Hz; 30s → 62.5 Hz; 30.001s → 61.5 Hz; 1800s → 61.5 Hz; 1800s → 60.5 Hz | Low: 0.1s → 57 Hz; 30s → 57 Hz; 30.001s → 57.5 Hz; 1800s → 57.5 Hz; 1800s → 58.8 Hz | verified |
Where these values come from
- LVRT Saudi Arabian Grid Code, Updated Version February 2022, Chapter 2 (Connection Code), clause 2.5.5.23(b)(ii) and Figure 2.5 'Voltage Withstand Capability Diagram' (p.34); continuous/30-min band from clause 2.4.3.
- HVRT The Saudi Arabian Grid Code, 2nd Electronic Update Oct 2016, clause 2.5.5.21: 'The Renewable Resource Generating Unit shall remain connected to the Network and continue stable operation if none of the phases exceeds 120% of nominal voltage for more than 1s'; clause 2.5.5.20(b)(ii) upper-side wording and Figure 2.3; steady-state ceiling per 2.4.3 = 1.1 pu.
- FRT Saudi Arabian Grid Code, Updated Version February 2022, clause 2.4.2.2 (Frequency Variations) table, Chapter 2 p.18.
