Certain investigations on maximum demand reduction at high tension consumer locations

Abstract

The development of a country depends on per capita energy consumption. The gap between electric power generation and the demand has been widening. The utility is not able to supply the required electric power for the existing consumers, due to lack of power generation. Many new consumers have been waiting for the electric power connection and some of the existing consumers have also applied for additional electrical power demand. Many villages are not yet electrified. Electrical Energy Management (EEM) in High Tension (HT) consumer premises gives benefits for both the consumer and the utility. The EEM is the scheduling process used to minimize the peak power consumption of a HT consumer. The electric cost of a HT consumer is calculated as a two part tariff method. The first part tariff is electric energy consumption cost in Kilo Watt Hour (KWHr), and the second part is the Maximum Demand (MD) cost in Kilo Volt Ampere (KVA).The first part of the tariff can be reduced by energy efficient operation of electrical equipments, and the second part of the tariff can be reduced by EEM. There are two types of operating processes of electrical machines in consumer premises. In the first case, all the electrical equipments are necessarily to be operated continuously, but in the second case, all the machines need not be operated continuously. In industries like Cement, textile and paper industries, all the processing units should be operated continuously, but in the granite industries, rice industries, and in educational institutions, all the electrical newlineequipments need not be operated continuously. newline newline
