Power Factor correction using a static capacitor

Calculation formulas as follows:

  • Q1 =  I losses + Cu losses
  • Q2 = PkW · (Tanφ1 – Tanφ2)
  • losses = 2% ·  Str
  • Cu losses = USC% · Str
  • Q = Q1 + Q2

Where:

  • Q1 = Reactive power to be compensated at the terminals of a transformer due to no load and load losses.
  • Q2 = Reactive power to be compensated due to total reactive components of lighting, power and mechanical loads.
  • Q = Overall reactive power to be compensated to achieve target power factor.
  • I losses = Transformer no load losses = Iron core losses.
  • Cu losses = Transformer load losses = Copper losses.
  • Str = Transformer rating (KVA).
  • P = Maximum demand load on the Main distribution board (kW).
  • φ1 = Inverse cosine of power factor before compensation.
  • φ2 = Inverse cosine of target power factor.
  • Usc% = Short circuit percentage impedance voltage of the transformer.

Power Factor Values assumptions before compensation:

  • For lighting outlets = 0.96
  • For power outlets and receptacles = 0.8
  • For motors = 0.8

Inputs = Transformer size + Transformer type + kVA Max. demand load for the whole system + PF before compensation + Target value of PF.

Outputs = Reactive power to be compensated at the terminals of a transformer due to no load and load losses.

  • Reactive power to be compensated due to total reactive components of lighting, power and mechanical loads
  • Overall reactive power to be compensated to achieve target power factor + circuit breaker size required to protect the capacitor bank.

    Hope we can do a schedule for PF correction instead of calculating each type of load separately
    Thanks

    A 1000-KVA transformer is loaded to 850 KVA at a power factor of 0.82
    lag. Calculate the leading kVAR necessary to correct the power factor to 0.95 lag.
    If the transformer has a rated conductor loss equal to 1.0% of the transformer rating,
    calculate the energy saved assuming 24-hour operation at the operating load.
