Power Factor

Power factor correction from real system data

Your load flow analysis already knows the real and reactive power in every branch. ekx shows you exactly where kVAR correction is needed and how much — from the actual model, not an estimate.

What you get

System power factor

Overall system power factor calculated from the actual loads in your model.

Real & reactive power flow

kW and kVAR flow visible in every branch of the system.

kVAR requirement

Required capacitor kVAR calculated to achieve your target power factor.

Location identification

See where reactive power is consumed most — place correction where it's most effective.

Impact on voltage

See how power factor correction affects bus voltages via load flow analysis.

Impact on losses

Reduced reactive current means reduced losses. See the impact in the load flow.

Power factor correction as part of system analysis

Instead of a standalone kVAR calculator with estimated values, ekx calculates correction requirements from the actual power flow in your model.

  • Load flow shows real and reactive power in every branch
  • System power factor calculated from actual load data
  • kVAR requirement derived from current vs target power factor
  • Voltage and loss impacts visible after correction is applied

Frequently asked questions

How does it calculate kVAR needed?

From the load flow analysis: current system kW and power factor versus your target power factor. The kVAR difference is the required correction.

Can I see the impact on voltage?

Yes. Adding capacitor correction changes reactive power flow, which affects bus voltages. Load flow recalculates to show the impact.

Does it suggest capacitor locations?

The load flow shows where reactive power consumption is highest, which is typically the most effective correction point.

Does it account for harmonic concerns?

Power factor correction sizing is based on fundamental frequency analysis. Harmonic considerations should be evaluated separately by the engineer.
