Abstract

Power factor Correction Optimization for inductive loads by using an automatic power factor compensator has been achieved in this work. The case study industry was modelled as an RL load and global compensation method of each section of the industry was the technique selected for the compensation so as to eliminate the cost of installing various smaller compensators on each machine. i.e. each section of the industry was lumped up and compensated from a suitable point. The circuit was achieved by connecting 4 capacitors in parallel on each phase for each section (12 capacitors per section). The capacitors were connected through a switching contactor. The AT89c51 microcontroller was programmed such that it automatically checks the capacitance required for a unity power factor and then produces a switching pattern for the contactors such that the capacitance in circuit at all times always achieves unity power factor. A cost analysis was also done in this work using the tariff of EEDC as at Dec 2017 to see the amount being saved as a result of compensation. The result showed the automatic compensation circuit was able to save the industry about 516 KVA in apparent power, reduce the total reactive power of the industry by as much as 1464 KVAR and about 9 million (55%) of their utility bill when the operating power factor was 0.74 and the utility bill was N37.83 per KVAh .
