Test methods

Power Quality and Harmonic Survey

Data records for Power Quality and Harmonic Survey.
RecordStatement
tests.power-quality-and-harmonic-survey.equipment.battery.acceptancePower Quality and Harmonic Survey is specified for battery energy storage systems in acceptance testing at clause 7.28.B.6 of ANSI/NETA ATS-2025. Value: battery energy storage systems.
tests.power-quality-and-harmonic-survey.governed-by.ansi-neta-atsPower Quality and Harmonic Survey is addressed in ANSI/NETA ATS-2025.
tests.power-quality-and-harmonic-survey.governed-by.ieee-519Power Quality and Harmonic Survey is addressed in IEEE 519-2022.
tests.power-quality-and-harmonic-survey.ieee1547-1.commissioning-procedureThe power quality commissioning procedure of clause 8.2.3.4 in IEEE 1547.1-2020 energizes the step-up transformer and observes the inrush, sweeps active and reactive power from zero to the available capacity, performs a hard disconnect and observes the response, and then observes the installation over time; the criterion is that the installation stays within the required limits of IEEE 1547-2018 as installed, and the procedure may be modified by documented agreement.
tests.power-quality-and-harmonic-survey.ieee1547-1.commissioning-when-requiredCommissioning test CT4 in clause 8.2.3.4 of IEEE 1547.1-2020, the power quality test, is required when issues arise at commissioning, when the design evaluation calls for it or when the Area EPS operator requires it, and its test cases (startup, disconnection, the full output range, input variation and nearby facilities) are agreed with the Area EPS operator. Measurements are taken at the PCC, except that dc injection and current distortion may be measured at the reference point of applicability, with an instrument of the Class A performance class defined in the IEC power quality measurement methods standard.
tests.power-quality-and-harmonic-survey.ieee1547.limitsFor a DER interconnection, clause 7 of IEEE 1547-2018 limits direct current injection, rapid voltage change, flicker (Table 25) and harmonic current distortion by harmonic order band and as total rated-current distortion (Table 26 and Table 27), each at the reference point of applicability or the point of common coupling as its subclause states; the harmonic measurement methodology follows IEEE 519, but the current distortion tables differ from those of IEEE 519 and harmonic current caused by pre-existing voltage distortion is excluded.
tests.power-quality-and-harmonic-survey.ieee2800.baselineClause 8.2 of IEEE 2800-2022 requires a baseline of transmission-system voltage harmonics at the reference point of applicability before interconnection, applies the harmonic limits at commissioning and afterwards as the transmission system owner directs, and states that pre-existing distortion should not be grounds for denying interconnection.
tests.power-quality-and-harmonic-survey.ieee2800.flickerClause 8.1.3 of IEEE 2800-2022 limits flicker emission at the reference point of applicability through Table 16, which states short-term and long-term flicker indices evaluated as a high-percentile statistic over a measurement period the clause fixes, using the measurement methods of IEEE 1453 and IEC TR 61000-3-7; a supplemental device may be used for mitigation.
tests.power-quality-and-harmonic-survey.ieee2800.harmonic-current-limitsClause 8.2.1 of IEEE 2800-2022 limits the plant's harmonic current at the reference point of applicability through Table 17, by voltage class and harmonic order band as a fraction of rated current, and Table 18 for certain even orders; the limits are absolute, include harmonic current sourced from the transmission system, and are evaluated as a high-percentile statistic over a measurement period the clause fixes.
tests.power-quality-and-harmonic-survey.titleThe test method is named Power Quality and Harmonic Survey. Value: Power Quality and Harmonic Survey.
