Minimising Penalty in Industrial Power Consumption by using APFC Unit and Maximum Demand Controller

The objective of paper is to minimizing the penalty of industries by improvement of power factor and maximum demand controller. In first method the industries used various load continuously running condition because of this the inductive load increases. So the power factor of system get reduces due to effect of inductive reactive power but the electricity board having standard limit regarding power factor value and if power factor of system reduces below the specified limit than electricity board charge penalty to industrial consumer .This penalty of industries is reduce by designing automatic power factor correction (APFC) unit. In second method in India, electricity demand is greater than the generation of power. Many industrial organization and various institutions used lot of power from grid but fail to utilize it in an efficient and economical way. In many case consumers draw excess of power than there sanctioned demand. They consumers pay the penalty to electricity board. Electrical energy can be utilized in proper way by using maximum demand controller. This paper illustrates how the maximum demand monitored and controlled using microcontroller. A prototype is designed we have to considering the various load and priority wise load switching is controller by the microcontroller in order to maintain the desired maximum demand.
