Abstract
When designing the power supply system for gas fields, the choice of supply and distribution grids is fundamental. This criterion is the conceptual parameter that affects the economic efficiency of the facility as a whole. A properly selected voltage class reduces losses during electrical energy transmission, capital investments and operating costs of an enterprise. The voltage should be selected taking into account the entire life cycle of the field, namely from pilot development to liquidation and transfer to underground gas storage or conservation. The purpose of the paper is to develop a mathematical model for calculating the voltage for a distribution grid made on single-chain supports of overhead power lines (overhead lines) with specified boundary conditions, such as the number of gas wells clusters, the overhead line length. The following assumption was assessed: the selected voltage of the electrical grid, taking into account the entire life cycle, increases the facility economic efficiency. The following research methods were applied: theory of experimental planning, complete factorial experiment, statistical method. The obtained research results are the mathematical model for calculating the choice of rational voltage and mathematical models for calculating discounted costs, performed using the theory of experimental planning and refined boundary parameters.
