Development of Measures to Optimize the Transformers Loading

Energy conservation and energy efficiency are one of the most important areas of the Russian economy modernization. The reactive power flowing through them has a significant impact on power losses in 6–10 kV distribution networks. Asaresult, electricity losses in individual networks reach 40%. Consequently there are excess losses, which must be paid for from profit. Therefore energy saving and increasing energy efficiency in distribution networks are an urgent task, the need to solve which is due to various technical and economic reasons. This work is aimed at developing measures to optimize the transformers loading of an oil pumping station with the compensating devices introduction. The dependences of the relative change in the transmission capacity, power losses and voltage losses with a change in the reactive power factor have been obtained. A model has been developed in the Matlab Simulink program to assess the power supply system efficiency of an oil pumping station. The power supply system simulation model of the oil pumping station makes it possible to select the compensating devices capacity and installation locations in the projected and existing electrical network in order to minimize electricity losses, as well as to control reactive power depending on power transformers load factor. The results obtained can be used in the development of energy conservation programs in the power grid complex.
