Testing and Evaluation of a Power Factor Correction for Power-Savings Potential
Abstract
Power factor correction (PFC) is an important technology that can be used to enhance power quality. It was noted that the power factor was low for packaged air-conditioning (PAC) units utilized in residential buildings in Kuwait. To study the impact of PFC units, a PAC unit was selected, a PFC unit was installed,and three cases were developed to assess their energy-saving potential. It was found that the PFC unit was able to correct the power factor from 0.61 to 0.96. The reactive power was then reduced from 13.9 to 3.0 kVAR (kilo volts amps reactive), the apparent power was decreased from
17.5 to 11.0 kVA (kilo volts amps). and the current was reduced from 23.4 to 14.5 amps. The Ministry of Electricity & Water (MEW) in Kuwait is expected to be the major beneficiary of installing PFC units since MEW does not charge consumers for the cost of reactive power..
Key words: PFC unit, power factor, reactive power, active power and apparent power.
