Electrical Energy Consumption Analysis in a Transformer Manufacturing Industry

Abstract

As far as a manufacturing industry is concerned, the electricity energy is a key resource, where micro-analysis is required, as it directly impacts the financial aspects. This project addresses this aspect, where the focus lies upon the processes involved that consume significant magnitude of electricity. To have the precise analysis of electrical energy consumption, the consumption can be categorized under fixed and variable consumption, where fixed consumption is independent of the manufacturing, while the variable consumption is directly dependent upon the manufacturing. So, to have a specific idea about overall energy consumption for manufacturing process of a single job, the contribution of both fixed and variable consumption must be analyzed independently. The analysis becomes complex as there are multiple factors in the manufacturing that are dependent on each other, and to obtain energy consumption per job, these factors must be taken into consideration. Hence, this is a discrete calculation, wherein when the energy consumption of one particular section is being calculated, the others must be treated as constants. However, the effects of other areas on the current section cannot be neglected. So, to know the energy consumption involved in manufacturing, it is necessary to know the entire manufacturing process the idea of the areas in which the energy consumption takes place. Further, the data of electricity consumption for last three financial years is displayed, to compare the actual variable energy consumption with the calculated. The calculation of variable energy consumption is obtained by deriving the energy consumption involved in various job samples of SR, ICT and HVDC.
