15 To Simplify Things to all of us... You can’t move the wheelbarrow(active power delivery)unless you lift the arms!(reactive power)
16 Electrical Power Types Almost all bulk electric power is generated, transported and consumed in an alternating current (AC) network.Elements of AC systems produce and consume two kinds of Power:Real Power “P” (measured in watts)It accomplishes useful work (e.g., running motors)Reactive Power (measured in vary).supports the voltages that must be controlled for system reliability
17 Power Factor φ φ φ Power factor (Pf) = The cosine of the angle between Voltage and currentsignals = coos φ.VoltageφCurrentPower factor (Pf) = The cosine ofthe angle between useful power andTotal power = coos φ = (P/S)Motor CurrentMagneticcurrentS=Total Power (KVA)Q MagneticPower(KVAr)φφUseful currentP=Useful Power (KW)
18 Why improve Power Factor? The benefits that can be achieved by applying the suitable Power Factor correction are:Environmental benefit. Reduction of power consumption due to improved energy efficiency. Reduced power consumption means less greenhouse gas emissions and fossil fuel depletion by power stationsReduction of Electricity BillsExtra kVA available from the existing supplyReduction of I2R losses in transformers and distribution equipmentReduction of voltage drop in long cablesExtended equipment life – Reduced electrical burden on cables andelectrical components18
19 Penalty Equation Electricity Bill! Pen=30000 USD Pen=160000USD For a PF between , the penalty per year in L.E (Pen.) is calculated as follows:(0.92-average PF)Pen.=Kwhr per year××0.5USDFor a PF below 0.72, the penalty per year in L.E (Pen.) is calculated as follows:(0.92-average PF)Pen.=Kwhr per year××1.0USDNumerical ExamplePen=30000 USDFor Kwhr with PF 0.8, we getPen=160000USDFor Kwhr with PF 0.6, we get
20 Bonus Electricity Bill! Bonus=10000 USD Bonus = × (PF-0.92) × 0.5 USD For a PF above 0.92, the Bonus per year in L.E is calculated as follows:Bonus=Kwhr per year×(PF-0.92)×0.5USDNumerical ExampleBonus=10000 USDFor Kwhr with PF 0.96, we get
21 How to improve Power Factor? Power factor correction is achieved by the addition of capacitors in parallel with the connected motor or lighting circuits and can be applied at the equipment, distribution board or at the origin of the installation.
22 So, what is happening? System without Power factor correction System with Power factor correctionCosφ = (P/S)Cosθ = (P/S1)QC(VARS)P (Watts)φθQL-QC (VARS)S1(VA)QL(VARS)S (VA)Capacitors contained in most power factor correction equipment draw current that leads the voltage, thus producing a leading power factor. If capacitors areconnected to a circuit that operates at a nominally lagging power factor, the extent that the circuit lags is reduced proportionately.
23 Now; we can say thatPower factor correction succeeded in the following:Decreasing the shift between P and S, thus increasing PFDecreasing the reactive power Q, thus reducing or eliminatingthe penalty from the electricity billPower factor correction Failed inDecreasing the active power “P”
