Arc Flash, Load Flow, Short Circuit, Protection Coordination, Transient Stability, Harmonics across Saudi Arabia. the Kingdom. Aramco SAES + IEC 61511 + IEEE 1584 + NFPA 70E multi-standard practice. SASO + SCE co-signature.
VB Engineering Saudi Arabia delivers the full Power System Studies stack from the the Kingdom across Aramco upstream + refining + petrochem, SEC grid infrastructure, and the broader Kingdom industrial estate. Aramco SAES (vendor approval) + IEC 60909 + IEEE Std 141 (load flow + fault) + IEEE Std 242 (coordination) + IEEE 1584 + NFPA 70E (arc flash) + IEEE Std 519 (harmonics). SASO standards + Saudi Council of Engineers (SCE) co-signature. Vision 2030 Saudization-compatible delivery model. Arabic-English bilingual where required.
Load flow, short circuit, arc flash, protection coordination, transient stability, and harmonics studies delivered with a Chartered Engineer signature on every page, for the the Jubail Industrial City (east coast petrochem) that Saudi Arabia operates.
Across the Aramco upstream-to-downstream chain, the SABIC integrated petrochemical complexes, and the Vision 2030 giga-projects, power-system studies are what make a brownfield retrofit defensible. Saudi Arabia's brownfield power-systems work concentrates around Aramco's upstream / downstream complex (Ghawar · Abqaiq · Ras Tanura · Jubail · Yanbu) and SABIC's integrated petrochemical platforms. Vision 2030 has added the Saudization-compliant industrial-cluster build-out, mining at Ma'aden, and the giga-project corridor. Aramco and SABIC's capital stock represents the largest brownfield electrical engineering market in the Middle East. Vision 2030 adds the giga-projects, but the recurring revenue is in the 5-year audit cycle on the existing plants · and that is where the brownfield digital engineering offer fits.
Every deliverable is mapped against Aramco SAES (Saudi Aramco Engineering Standards) · Aramco GI (General Instructions) · IEC 60909 · IEC 61936 · NFPA 70E (referenced in SAES-P-100 series). Where the operator references additional standards, we engineer in parallel against IEEE 1584 (arc flash) · API RP 540 · IEC 60079 (hazardous area) · SEC Distribution Code (for SEC-fed loads) · SABIC TS (Technical Specifications). The conformance matrix on page one of the report calls each section against the relevant clause so Aramco Operations Coordination Center (OCC) · SEC (Saudi Electricity Company) review the deliverable in the format they expect.
Time-current curves graded for selectivity across 13.8 kV to 13.8 kV. Setting workbook in the format your AMS accepts. Where coordination drift is identified against the as-found CT/PT ratios, we rebuild the recommendation from the most upstream device down.
Motor-starting voltage dip during simultaneous restart, generator stability under fault clearance, and ride-through during voltage-recovery events. Where the Saudi Arabia grid-code requires fault-ride-through, we model against the published curve.
Harmonic measurement at the PCC against IEEE 519 + SEC limits. Spectrum capture at every drive load. Filter design where the PCC distortion is outside limit. Measurement campaign with a calibrated PQ analyser is included.
BIL coordination across the voltage levels. Surge-arrester selection at the intake. SPD class-by-class selection at LV distribution. Where lightning exposure is documented (a recurring driver for Eastern Province winter storms), the surge protection package covers the equipment fleet directly.
Steady-state load flow under base, contingency, and N-1 conditions. Voltage profile mapped across 13.8 kV to 13.8 kV. Tap-position recommendations for transformer LTCs. The deliverable closes any voltage-regulation finding from the previous study or insurer walk.
Three-phase, line-to-line, and single-line-to-ground fault calculations to IEC 60909 (Aramco SAES interpretation layer). Breaker rating reconciliation against the as-installed equipment fleet at Aramco upstream Ghawar / Khurais. Asymmetrical current and X/R ratio captured at every bus.
Incident energy at every working position, calculated to IEEE 1584-2018 (the 2002 method is retired in our practice). Arc flash boundary, restricted approach, and PPE category by bus. Labels print in the format IEEE 1584 + SAES labels in bilingual Arabic-English expects.
Three Saudi engagements (across Aramco upstream, SABIC petrochem, and Ma'aden mining) that show the working pattern:
a gas plant with 13.8 kV intake and 3 motor-driven gas-injection compressor trains.
The engagement: SAES-P-114 compliance review found motor starting voltage dip below threshold during simultaneous restart; transient stability study confirmed and revised starting sequence.
a 1.5 MTPA cracker with 115 kV grid tie and 13.8 kV distribution.
The engagement: Harmonic measurement at the PCC outside SEC code limit because of the variable-speed drive fleet; filter design and harmonic mitigation program.
a phosphate beneficiation plant with 33 kV captive substation and 5 MVA crushing-mill drives.
The engagement: Arc flash incident at the mill MCC initiated full-plant 70E-equivalent re-baselining; HCIS-aligned safe work practice rollout.
