Power-quality simulation and standardised power-quality report

Harmonic simulation outputs raw harmonic current / voltage values only: there is no complete power-quality compliance summary and no standardised report chapters.

Built-in chapter list (from the specification)The specification asks for 7 chapter(s); the engine can produce 6 of them for this report.
Standards basisIEC 61000 series; IEEE 519; GB/T 14549; national DER grid-connection power-quality codes.
⚠ The specification switch `studyOptions.enablePowerQualityReport` is NOT wired. The engine produces power-quality content under separate switches (harmonic flow, PV power quality, three-phase unbalance, unbalance time series, PV PQ envelope, VFD model). Two chapters of this report are explicitly out of scope in our own specification (IEC 61000-4-15 flicker, inter-harmonics), so the report is only partially covered.

Built-in chapter list (from the specification)7 chapter(s)
  1. 1.Report overview: project name, model version, simulated cases, selected power-quality standard (switchable code package: IEEE 519 / IEC 61000 / GB/T 14549 etc.); simulation assumptions and boundary statements, scope of applicability, disclaimer (simulation assessment, not on-site measurement); power-quality indicator overview table with a compliance verdict for every bus (pass / warning / exceedance).
  2. 2.Harmonic analysis chapter: harmonic simulation settings (harmonic-source location, harmonic order range 2-50); total harmonic voltage distortion THDu and total harmonic current distortion THDi per bus; harmonic voltage and current magnitude tables per order; harmonic spectrum charts (voltage and current); per-order exceedance verdicts listing the offending order, magnitude and percentage above the limit; harmonic impedance scan results and before / after filter-switching comparison where a passive-filter model exists.
  3. 3.Three-phase unbalance chapter: negative-sequence voltage unbalance factor and negative-sequence current per bus; three-phase voltage and current comparison tables; unbalance time-series curve in time-series simulation mode; buses flagged against the code limit.
  4. 4.Voltage sag and swell chapter: fault-case list (three-phase fault, single-phase-to-earth fault etc.); residual bus voltage for each fault; sag magnitude table and fault-location / affected-bus list; sag risk verdict (quasi-steady-state static estimate only, no dynamic time trajectory).
  5. 5.Voltage fluctuation and flicker (simplified engineering estimate) chapter: fluctuating-load settings and time-series load-fluctuation data; short-term flicker Pst and long-term flicker Plt engineering estimates; flicker verdict; note that this is a simplified model, not the IEC 61000-4-15 flickermeter algorithm.
  6. 6.Compliance conclusions and risk summary: consolidated list of all power-quality indicators; risk grading (low / warning / severe exceedance); explanations and engineering recommendations for exceedances (add filters, adjust short-circuit capacity, optimise DG grid-connection point).
  7. 7.Appendix: simulation parameter extract (system impedance, DG / load harmonic-emission parameters); reference standard clauses and limit tables; model assumptions and simplified-model notes.

Explicitly out of scope (from the specification)6
  • · Quasi-steady-state algebraic model; no high-accuracy time-domain waveform simulation.
  • · Flicker uses a simplified engineering estimate, not the full IEC 61000-4-15 flickermeter algorithm.
  • · No inter-harmonics and no high-frequency harmonics.
  • · No dynamic flicker from random load fluctuation.
  • · No sag-duration dynamic curve — only the fault steady-state residual voltage.
  • · Conclusions are for pre-assessment of a scheme only; they are not a substitute for an on-site measured power-quality report.

Sends one design request with exactly the switches below enabled. Nothing is calculated when the page opens.
