POWER QUALITY · SAUDI ARABIA

Power Quality Analysis for Saudi Industrial Sites

Power quality limits in Saudi Arabia are set at a boundary, and which boundary depends on the asset. A plant connected to the Saudi Electricity Company is measured at its point of common coupling under SEC requirements. Inside an Aramco facility the SAES-P standards apply instead. On the giga-projects the grid is effectively private, so the limits are the project's own.

What a Saudi Power Quality Study Has to Establish

Measurement is the easy part. Knowing which limits you are measured against, and at which point, is what makes the result usable.

What We Deliver

The governing point of common coupling

Harmonic and flicker limits apply at a defined boundary. For an SEC-connected plant that is the utility interface; inside an Aramco asset or giga-project grid it is internal, and measuring at the wrong point answers the wrong question.

WHAT GOES WRONG

Where Saudi Power Quality Studies Fail

Most rejected power quality studies measured correctly and concluded wrongly, because the limits applied were not the limits the asset owner uses.

  • Harmonics judged against IEEE 519 when the asset owner specifies SAES-P limits.
  • Measurement taken downstream of the real point of common coupling.
  • A single short recording used to characterise a plant with seasonal load variation.
  • VFD and UPS contributions assessed at part load rather than across the operating range.
  • Giga-project sites assessed against SEC limits when the grid is private.
  • No re-measurement after a filter, capacitor bank or large drive was added.

THE OUTCOMES

What the Report Contains

The report names the limit set and the measurement point before it presents a single number, because a distortion figure without those two facts cannot be checked by anyone downstream.

How We Run a Saudi Power Quality Study

01

Establish the governing limits

Confirm whether the site answers to SEC requirements, Aramco SAES-P or a project specification, and fix the point of common coupling before any instrument is installed.

02

Clear permits and access

Arrange permit to work and HSE pre-mobilisation, and confirm HCIS constraints on electrical room access where the facility is security-cleared.

03

Measure across the operating range

Install recorders at the agreed points for a window long enough to capture real plant behaviour, including the heaviest drive and process loading.

04

Analyse against the limit set

Assess voltage and current distortion, individual harmonic orders, flicker and unbalance against the standard that actually governs the asset.

05

Report and recommend

Findings with mitigation options, expected effect and the measurement basis, in a form the asset owner or underwriter can audit.

Frequently Asked Questions

It depends on the asset. IEEE 519 is widely applied at the point of common coupling for facilities connected to the Saudi Electricity Company, and the IEC 61000 series covers emission and flicker. Inside Aramco facilities the SAES-P electrical standards govern instead, and the giga-projects run effectively private grids with their own specifications. The study has to state which set it used.
At the point of common coupling that the governing limits refer to. For an SEC-connected plant that is the utility interface. Inside an Aramco asset or a giga-project grid the relevant boundary is internal. Measuring downstream of the correct point commonly produces a result that looks compliant but answers a different question from the one the asset owner asked.
Long enough to capture the plant's real operating range rather than a convenient snapshot. Sites with large variable speed drive populations, batch processes or seasonal loading need a recording window that includes the heaviest conditions. A short recording taken during light load is the most common reason a study has to be repeated.
They usually dominate the harmonic profile on Saudi industrial sites, so yes. Both behave differently at part load than at full load, and assessing them at a single operating point understates their contribution. We measure across the range and identify which sources drive the distortion before recommending filtering.
