Reactive-power compensation and power-factor optimisation report

Power flow outputs reactive power and power factor, but there is no standardised report covering compensation-scheme selection, compensation-capacity calculation and switching verification.

Built-in chapter list (from the specification)8 chapter(s)
  1. 1.Report overview: project information, simulated cases, target power factor, standards applied, model assumptions and disclaimer.
  2. 2.System reactive-demand analysis: reactive deficit / surplus per bus, reactive characteristics of loads and DG.
  3. 3.Compensation-capacity calculation: reactive compensation capacity sized for the target power factor.
  4. 4.Before / after comparison: bus voltage, power factor and network losses with capacitor / reactor switched in and out.
  5. 5.Harmonic resonance risk check: harmonic impedance scan of the system after the capacitor is inserted, screening for parallel-resonance risk.
  6. 6.Multi-case verification: operating state of the compensation equipment at maximum output, minimum output and N-1.
  7. 7.Conclusions and engineering recommendations: installation location, group-switching strategy, capacity recommendation, resonance-risk mitigation.
  8. 8.Appendix: element parameters, reactive-power formulas, limit tables.

Explicitly out of scope (from the specification)4
  • · Quasi-steady-state algebraic model; no capacitor-switching transient inrush simulation.
  • · No closed-loop dynamic response of dynamic reactive devices (SVG).
  • · No capacitor ageing or capacitance decay.
  • · For sizing estimates only; it is not a substitute for detailed design by the equipment manufacturer.

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