Automated Design of Power Distribution Network for Oil and Gas Industry
One of the important tasks of the oil and gas industry is to reduce the hydrocarbon production cost. It is known that the share of electricity in operating costs in the field can reach 40%. This means it is one of the important factors affecting the economy of oil and gas production. Cost-cutting efforts could be started at the planning stage of the facility by optimizing the structure of the power supply system and the equipment composition. The paper deals with the methodology of automated power distribution system planning for oil and gas industry and its software implementation. The power distribution system planning includes: selection of the connection points to the existing power network, optimal places for the transformer and distribution substations location, determination of the transmission lines voltage classes, transmission lines route taking into account the geographical features and determination of the required parameters of the equipment. A list of limitations and assumptions when choosing parameters and locations of equipment in accordance with the requirements of the Russian electrical Installations code is briefly presented. The optimization algorithm and the mathematical methods are described in detail. The algorithm provides for an assessment of the company generating capacities, as well as potential points of connection to the external network. The possibility of corridor design of transmission lines along roads is included. The software product was developed as a decision support tool for investment planning and development of new oil and gas fields. The module allows calculating the total cost of ownership of an object, and work schedule in the form of a Gantt chart. The paper also proposes an approach to creating an ontological model of oil and gas production enterprises acting as a set of processes affecting objects and their properties.
