On power transformers energy efficiency based load transfer analysis

Abstract

Transformers have an important role from the production of electricity energy to consumption. Because they are responsible for ensuring that power transfer is carried out appropriately in many stages. Therefore, power transformers work in many places, from the production phase of electricity to the transmission and distribution phases. If various time periods are taken into consideration for energy using, power transformers can operate at small powers or very small powers. This small-power operation, which can be defined even as minor quantity, is counter-productive as a proportional increase in energy loss. The small working power, because of this loss ratio, is not taken into consideration; but considering large number of power transformers in annual periods, it can cause the serious losses and the costs emerge. In this paper, we propose a dual transformer control model in which apparent time periods with little load are determined by software, and in those periods, the load is fed by power transformers of smaller power or fewer. In this model, we worked for reducing the amount of power loss and energy costs during periods. Reduced load is demonstrated in following parts by statistical results.
