Management of reactive power in industrial installation and economic analysis

Electrical power is indispensable for each industry. To save energy cost, enchased safety and to maintain a strategic distance from power outage unsettling influence, the management of power is important .Industrial plants require a stable and advanced electrical net-work. There are various techniques for reactive power management which are being adopted for transmission and distribution of electric power from the utility side, but this is very important for the consumers also to manage this power in terms of better power factor, which directly relates to the monetary and power saving. This can be achieved by proper selection and installation of electrical equipment during industrial establishment. In this research article the old system of electrical installation for an inductive load of 1543 kilowatt and 650 kvar at an average power factor of 0.72 are suggested to modify by the new installations, whose equipment specifications are based on a desired power factor of 0.95. The total current of 1279.36 amperes taken by this inductive load is divided into ten branches. To manage the reactive power components of each branch, the selections of equipment are carried out with the help of eta PRO software.
