Automatic Optimization and Control of Power Factor, Reactive Power and Reduction of THD for Linear and Nonlinear Load by Using Arduino UNO

Aim of this paper is to discuss about power quality of the AC system, which has become a great concern due to the rapidly increased use of inductive loads, electronic equipment (Linear and Non linear load). We are wasting a part of the electrical energy everyday due to the lagging power factor in the inductive loads which is used in the system. Hence, there is an urgent need to avoid this wastage of energy, lower power factor and reactive power results in poor reliability, safety problems and high energy cost. The power factor of power system is continuously changing due to differences in the size and number of the equipment being used at a time. This makes it challenging to balance the inductive and capacitive loads continuously. Many control methods for the Power Factor Correction (PFC) were proposed. This paper presents a computationally accurate technique to design and development of a single phase as well as three phase power factor correction, reactive power and THD compensation using Arduino Uno micro-controlling chip. The hardware implementation is developed by using Arduino Uno board.
