Estimation of Economic Viability of Reactive Power Compensation on Gas Production Industry Facilities, Based on Energy Consumption Data

The relevance of the study is driven by the presence of numerous reactive power consumers in the power supply systems of gas production industry facilities. However, in existing and dynamically developing power supply systems, it is difficult to assess the most probable operating modes of electrical equipment and there could be no data on its reactive power consumption. Installing reactive power compensation devices under such circumstances may not be economically viable. Therefore, the development of methodologies for determining the boundaries of the economic feasibility of power factor correction in conditions of uncertainty becomes a relevant task. The aim of the study is to determine the economically reasonable level of reactive power compensation for the power supply system of an operational industrial enterprise, taking into account electrical energy losses, network elements load, voltage level, and the cost of reactive power compensation measures, assuming that data on the reactive power factor of consumers is unavailable. The research object is the power supply system of gas production industry facilities. To achieve this goal, used methods of mathematical modeling, and linear optimization. Results and conclusions: Presented methodology for determining the economically feasible level of reactive power compensation in the absence of some initial data on power supply system consumers and their operating modes. Using this methodology, the power and installation location of compensating devices were determined based on data on active and reactive power consumption and the power supply system's topology, using the criterion of minimizing costs under real and maximum electrical load conditions.
