“…Moreover, minimum and maximum allowable limits of reactive power drawn from the system are defined in regulations and the electric distribution companies give penalties to the industrial consumers for any violation of these limits. As a summary, the advantages of PF correction are reduced system losses, increased load carrying capability of the conductors and the transformers, and improved voltage profile and system stability [9][10][11][12][13]. Although there are some expensive solutions to handle the reactive power compensation function, the capacitors are still used globally due to their simplicity and low cost.…”

“…When compared, the capacitors are much cheaper and easier to implement than static var compensators, static synchronous compensators, and active power filters [1][2][3]. On the other hand, many studies proposed the use of a microcontroller to improve the PF of only lagging loads by adding parallel connected capacitor banks to the load [1][2][3][4][5][6][7][8][9]. Arduino Uno has been used to improve only the lagging load by using capacitor connection in parallel with only the inductive load [1,6,7] and to improve the PF of different loads by using filter and capacitor bank [8].…”

Power Factor (PF) correction is a major power quality function in electrical distribution systems. This paper proposes a low-cost Automatic Power Factor Correction (APFC) system to increase the PF of both lagging and leading single-phase loads. The Arduino Mega 2560 microcontroller was used to calculate the PF and activate the relays that connect the capacitor/inductor banks to the load in parallel. Thus, the required capacitive or inductive reactive power was produced by the APFC system by automatically connecting the capacitor/inductor banks to the load in parallel. The APFC system can also measure and display many electrical parameters of the load such as the rms voltage, the rms current, PF, and the real, reactive, and apparent power on an LCD display. Two zero-crossing detector circuits are used to find the phase angle difference between voltage and current waveforms of the load. The measurement ability of the APFC system was tested for resistive, inductive, and capacitive loads with two different sizes. The measurement results were compared with the measurements of a commercial digital power meter and a measurement error of less than 8.0% was observed. The PF correction ability of the APFC system was verified for inductive and capacitive loads with two different sizes. The experiments show that the PF increased to close to unity for both lagging and leading loads.
