The article presents the mathematical description of minerals industry enterprises electrotechnical complexes. The presented development and modification of algorithms and methods for calculating the parameters of electrical complexes structural elements are taking into account the specifics of the technological process. The developed methods of studying the operating modes of electrical complexes of oil and gas production enterprises are planned to be used to identify various promising dynamic modes, which, in turn, will allow determining the optimal operating conditions of electrical complexes regardless of their structure, including in conditions of uncertainty and incomplete information.
Oil production is a complex technological process that requires significant electricity consumption. The main electricity consumers in oil and gas production workshops are artificial lift facilities. Currently, among the objects of mechanized mining, installations of electric submersible pumps are widespread. When planning technological modes, it is necessary to be able to assess the change in the power consumption parameters when changing the technological process parameters. The paper proposes a typical replacement scheme for the electrical complex element. The power consumption calculation of electric submersible pump installations has been carried out. The error in the power consumption modeling results of electric submersible pump installations in comparison with the results of instrumental measurements is no more than 10%. The estimation of additional losses of electric energy caused by the influence of harmonics is carried out. The proposed technique makes it possible to estimate the power consumption of an electric submersible pump installation when changing the parameters of the technological process and equipment. The results of the work can be used for planning material support and optimization of warehouse stocks within the framework of integrated logistics support for the technological process of industrial enterprises.
