Harmonic resonance scan and passive filter design report

Power quality outputs THD, but there is no system harmonic-impedance scan, no resonance-risk assessment and no passive-filter selection assessment.

Built-in chapter list (from the specification)The specification asks for 8 chapter(s); the engine can produce 1 of them for this report.
Standards basisIEC 61000; IEEE 519; engineering practice for harmonic resonance analysis and passive filter design.
⚠ The specification switch `studyOptions.enableHarmonicResonanceReport` is NOT wired. Harmonic resonance scanning and passive-filter design are implemented under `enablePassiveFilterDesign` (`engines/passive-filter.js`, chapter `passive-filter-design`) plus `enableHarmonicFlow` and the resonance scan (`engines/harmonic-scan.js` / `engines/resonance.js`).

Built-in chapter list (from the specification)8 chapter(s)
  1. 1.Report overview: project information, harmonic sources, candidate filter schemes, scan frequency range, standards and model assumptions.
  2. 2.System harmonic impedance scan: frequency-impedance curves at different buses and identification of resonance points (parallel / series).
  3. 3.No-filter baseline harmonic results: existing system THD, harmonic magnitudes per order, resonance-risk verdict.
  4. 4.Passive filter scheme simulation: harmonic indicator comparison before / after switching single-tuned or high-pass filters.
  5. 5.Verification of filter capacity, resonance frequency and impedance parameters; filter overload check.
  6. 6.Multi-case verification: filter stability under load variation and DER output variation.
  7. 7.Conclusions and mitigation recommendations: recommended filter scheme, installation location, resonance-risk avoidance measures.
  8. 8.Appendix: raw impedance-scan data, filter parameters, harmonic limit tables.

Explicitly out of scope (from the specification)4
  • · Quasi-steady-state frequency-domain harmonic model; no time-domain transient resonance inrush simulation.
  • · No resonance-point shift from filter component parameter drift or ageing.
  • · No dynamic closed-loop simulation of active filters (APF).
  • · Filter schemes are preliminary engineering selection only; final design requires review by the filter manufacturer.
