Abstract

This paper discusses the improve power factor and reduce the harmonics distortion of system. Poor power factor costs our community in increased electricity charges and unnecessary effect in the system and poor power quality. In electrical plants the loads draw from the network electric power (active) as power supply source (e.g. personal computers, printers, etc.) or convert it into another form of energy (e.g. electrical lamps or stoves) or into mechanical output (e.g. electrical motors) or rectifier. To smooth such negative effect, the power factor correction of the electrical plants is carried out. The power factor correction obtained by using power factor correction switches banks to generate locally the reactive energy necessary for the transfer of electrical useful power, allows a better and more rational technical-economical management of the plants. The system is capable of correcting power factor up to unity or adjusting it according to user desire. The proposed system is characterized by, no generation of harmonics, and reduction of transmission losses. Simulation results are reported and proved to be in good agreement with the relevant experimental results.
