Surveying Power Substation Designs: A Critical Analysis of Existing Literature

Power substations are essential installations of electrical power systems, responsible for directing the flow of energy, diversifying routes, modifying voltage to make it suitable for different applications. Present at the beginning and end of transmission and distribution lines, substations play a fundamental role in the reliable and efficient operation of the electrical system, allowing the transmission of electricity over long distances and its distribution to end consumers. The growing demand for electricity and consequently the expansion of the electrical system has contributed to the increase in these installations and consequently studies in the area. This work presents a literature review, based on the bibliometric analysis method, of the researches developed in the area of substation arrangement. The objective of the work is to present the state of the art related to the subject of electrical energy substation arrangement, indicating the most relevant publications on the topic. For this study, academic productions from undergraduate and graduate courses, journal articles and publications in conferences on the Scopus and Capes Periodicals platforms were considered due to their scope, organization of data and relevance. After analyzing the articles presented, it appears that, despite being of great importance for the electrical sector, the subject is not frequently discussed in the literature. Regarding the countries that have published the most in the last 5 years about the arrangement of substations, China stands out, which is in first place with 14 publications. Brazil occupies the sixth position in related productions on the subject.
