The difference between short circuit current contributions from renewable and conventional generators may affect protection system operation. Fault phase selection is one of the elements to be analyzed under renewable generation scenarios due to its importance in protection functions such as distance protection. The digitization of substations presents new opportunities in control and protection systems, such as functionality increase, reliability improvement, cost reduction of the installation and capacity for remote maintenance. This paper proposes a multi-criteria fault phase selection algorithm developed to be implemented in digital substations. The proposed faulted phase algorithm combines the results provided by four independent protection algorithms and has been designed to be applied in transmission power systems. Depending on the electrical variables measured in each event, quality criteria are defined to consider the strengths and weaknesses of each independent algorithm. The proposed algorithm has been implemented and tested on the centralized protection and control platform called EPICS, obtaining very satisfactory results. info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 5.0 2023 ENGINEERING, ELECTRICAL & ELECTRONIC 65 / 353 = 0.184 2023 Q1 T1 1.711 2023 Energy Engineering and Power Technology 2023 Q1 Electrical and Electronic Engineering 2023 Q1 12.1 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Comech, Maria Paz Universidad de Zaragoza (orcid)0000-0002-4133-7553 Prada Hurtado, Anibal Antonio Olivan, Miguel Angel (orcid)0000-0001-7025-061X Rodriguez del Castillo, Carlos López Cortón, David Gallego, Rubén Andrino 5009 535 Universidad de Zaragoza Dpto.
