A Method of Finding Capacitor Value for

In recent years, increasing attention has been paid to minimize the energy cost and inefficiency in electricity generation, transmission and distribution. This paper presents an approach in order to determine the size of capacitor in power system to minimize investment cost and energy loss and for improving power factor. The distribution system has been designed using Lab view software. Different components of Lab View software are used for calculation of the rating of capacitor bank required installing in the proposed system. Power factor correction is one of the techniques recently applied to the electric distribution system. In this paper the power factor of the circuit without the use of capacitor bank has been assumed. Then to improve the power factor to a desired value the size of the capacitor bank required to compensate the load reactive power has been calculated. The results of the developed circuit are compared with the manual calculations. Shunt capacitor banks are used to improve the quality of the electrical supply and the efficient operation of the power system. Shunt capacitor banks are relatively inexpensive and can be easily installed anywhere on the network. Finally, loss reduction and power factor improvement economically justified the use of this method.
