Design of energy efficient electrotechnical complexes with an autonomous electric supply system

Abstract

Improving energy efficiency and reducing the costs of creating an autonomous power supply complex for an oil production enterprise is an urgent problem and requires a rational solution. At each stage of the electrical complex development of the oil production enterprise, the purpose is to increase energy efficiency in order to reduce the unit cost of electricity per unit of produced well fluid volume. The electrical complex energy efficiency assessment of the oil production enterprise can be determined by the classical methodology of the energy balance. The task of increasing the energy efficiency of the electrical complex with an autonomous power supply system is to ensure a minimum of fuel costs while maintaining current oil production. Two types of the electrical complex models are proposed: with an individual electricity source and a generation center based on individual diesel generators. A method for calculating the energy parameters of the electrical complex components with installations of different types of pumps is presented. In this case, the energy efficiency is improved due to joint deep and group reactive power compensation and power factor correction by reducing the harmonic components of the current. The electrical complex simulation of a submersible electric motor has been carried out in order to determine the values of voltage and current during switching processes. The autonomous power supply system modeling of an oil production enterprise in case of voltage losses and the simulation of diesel generators with a frequency deviation of the generated voltage during load surges was carried out.
