This article presents the issues that must be considered for the modern-ization of the power systems in the national refining industry (nri) in Mex-ico and the migration to gas-insulated substations (Giss). the nri increased its production capacity and demand for electrical power, requiring sources of electricity and equipment that deliver higher availability, reliability, and security of the supplied electricity. the selection of new technologies should represent an improvement in effi-ciency, preserve the overall operational security of the plants, and solve the actual power systems' problems. among the new proposed requirements are the migration of the distribution level from 13.8 kV to 34.5 kV or to 115 kV, as well as the use of Giss and hybrid substations (hss). the Gis technology itself represents a major tech-nological breakthrough for repowering and modernizing power substations due to its innovative features, high quality of equipment, and higher reliability, which repre-sents the use of sulphur hexafluoride (sF6) as the insulat-ing medium. in addition, this article exemplifies the conceptual schemes proposed to restructure the power system for the Mexican refineries by 2015. The selection of technology allowed the actual conditions to be identified, thereby offering technical solutions that could be useful in similar projects. © 2014 IEEE.

This paper present the issues to consider, for the modernization of power systems in the National Refining Industry (NRI) in Mexico, and migration to gas-insulated substations (GIS). The NRI, increases its production capacity and demand of electric charge, requiring electrical supplies and equipment to provide higher availability, reliability and security of supply of electricity. The selection of new technologies, should present an improvement in efficiency, preserve operational security and integral of the plants and solve the problems in the power systems of the NRI. Between the new requirements posed, is the migration of the distribution level of 13.8 kV to 34.5 kV or 115 kV, and the use of GIS's and hybrid substations. The GIS's technology represents a major technological advance for repowering and modernization of power substations used in the NRI, due to innovative features, high quality of teams and reliability which represents SF6 as insulating medium. Also this paper shows the conceptual schemes proposed to restructure the electrical power system for the refineries by 2015. The results of the analysis allowed to identify the current conditions in the NRI, and thereby to offer technical solutions that could be useful to engineers facing similar projects. © 2012 IEEE.
