In Electrical distribution network, type of load causes difference in power dissipated in load against actual power supplied by the source, this is due to resistance, inductance & capacitance components of the load. These components either dissipate energy or store energy while doing the work. Due to this there is a phase shift caused at the load compared to the source, this is called as Power Factor.
In Today’s world, there many non linear loads added into distribution network, these further distorts the voltage and current of that circuit. With this symptom we need to calculate Power Factor for Fundamental components and all other Harmonic order of components. By measurement and mitigation of these symptoms one can take right decision and improve efficiency of the Network. Power Factor is indicator of quality of design and quality management of electrical assets.
Following are various Power Factors effective in Electrical Network: Power Factor (PF), Total PF, True PF, Displacement PF. Analysis of these and mitigation based these PF can help increase Efficiency of Network.
Power Factor (PF):
Power Factor (PF) is the Degree to which voltage & Current to load are out of phase.
Total PF:
Total Power Factor is the difference between total power delivered by utility and the portion of total power which has does useful work.
True PF:
True Power Factor is the ratio of real power (KW) to apparent power (KVA) including complete harmonic contents.
Displacement PF:
Displacement power factor is the cosine of angle between fundamental component of Current and voltage, it gives time lag between fundamental components of Voltage and current.
Power Factor is measure of how effectively load consumes electrical energy to produce effective work. Higher the power factor, more the work produced for given current and voltage. Most Utilities charge (given Incentive/Penalty) consumers for average Power Factor maintained throughout the billing cycle.
