Rationing of electric reliability of oil industry facilities at the design stage

UDK: 658.26:621.31
DOI: 10.24887/0028-2448-2019-3-40-45
Key words: electric reliability, categories of electric receivers, power supply sources, rationing of electric reliability
Authors: V.P. Frayshteter (Giprotyumenneftegas PJSC, HMS Group, RF, Tyumen)

The design of oil and gas facilities in terms of the reliability of their electrical supply is carried out on the basis of the categories of reliability defined by the electrical installation standards. This classification of electric receivers according to the rationing of their electric reliability has existed for more than half a century. The article tackles the deficiencies of the existing system. It is noted that the existing system of the electric reliability rationing is mainly of the descriptive character. It does not contain any qualitative indicators, except for a number of independent power sources. The deficiencies of the current system of electric reliability rationing are shown on the example of oil production facilities. It is also exposed that some provisions of the current standards are contradictory.

It is proposed to use a special reliability requirements coding system for the purposing of power supply system design. This proposed system is based on the existing categorisation system but is enhanced with additional requirements. These additional requirements define the technical solutions for the scheme of normal power supply by backup and emergency power sources. The purpose of the proposed coding system is to fix the main requirements for the power supply system of the electric receiver or consumer of electricity in a concise and standardised form. These requirements are to be implemented during the design stage. An advanced algorithm for coding requirements for the reliability of power supply is proposed; examples of such coding are given. The purpose of the proposed coding system is to encrypt a large amount of information (requirements) in a short formula.

The analysis of the existing system of electric reliability rationing and the proposed coding algorithm are considered on the example of power supply of oil production facilities. All conclusions and recommendations are of universal character, i.e. they can be used without reference to a specific industry.
