Power compensation enables the interests of the user and those of the energy distribution company to be combined, by improving the efficiency of installations through better use of the available power by limiting the consumption of reactive energy that is not only unnecessary and expensive but also a source of overcurrents in conductors.
Accordingly, installing capacitors in the network improves the power factor and hence decreases the reactive power. Methods and Objectives: This paper presents an approach to maximize the saving in terms of financial costs, energy resources, environmental protection, and also to enhance the power system efficiency.

Accordingly, the expected beneficiaries from improving the power factor are mainly large inductive networks such as large scale factories and industrial field.
The effects of a fixed capacitor-bank and an SVC have been analyzed regarding their benefits to an uncompensated power supply system. The input data of the conducted simulation model had been taken from an experimental measurement in the Electrical Machines Laboratory of VIT University Vellore (India).
Over-compensation (Ic >Ir), increases the apparent current consumed and also increases the voltage applied to the equipment. The illustration of vectors V2S (with over-compensation) and V2 (with appropriate compensation) shows this phenomenon, which must be avoided. Care must be taken when choosing energy compensation.
