The development of energy loss reduction methods for oil and gas field transformer substations

Abstract

The performance coefficient is the most informative factor of transformer substation operation. It shows the
dependence of the energy loss on the change of the transformer installed load. It is necessary to redistribute the
consumers’ load (e.g. electric centrifugal pumps, sucker-rod pumps) among substations to minimize the total energy
loss. In this case, the geometric programming method was proposed to calculate the global extremum. The main
advantage of this method is an analytical type of the calculation model for optimization task solution without
numerical methods and iterative procedures being applied. The proposed method also allows optimizing the transformer
substation load in case of the installed load change in time (pump emergency shutdown).
