The CPC operation requires a proper signal processing module that provides the necessary parameters and signals accurately and at times needed to ensure the platform’s control and protection services can operate correctly. This paper proposes and implements a sampled values-analog processing module (SV-APM) for a software-based CPC in a digital substation developed in the framework of the EPICS project. The SV-APM decodes the digital messages published by merging units and extracts the information required by control and protection functions implemented in a software-based CPC platform. To check SV-APM performance, a set of tests is carried out using Real-time digital simulator (RTDS) and EPICS platform in Hardware in the Loop configuration (HiL). These tests evaluate SV-APM behavior against disturbances in communication channels, voltage and current variations, harmonic contents and frequency variations. Furthermore, latency tests are carried out to evaluate CPC response times. From tests, it is concluded that SV-APM output satisfactorily fulfills all the time response and accuracy requirements demanded during its development. info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 3.6 2024 COMPUTER SCIENCE, INFORMATION SYSTEMS 93 / 258 = 0.36 2024 Q2 T2 TELECOMMUNICATIONS 51 / 120 = 0.425 2024 Q2 T2 ENGINEERING, ELECTRICAL & ELECTRONIC 130 / 368 = 0.353 2024 Q2 T2 0.849 2024 Computer Science (miscellaneous) 2024 Q1 Engineering (miscellaneous) 2024 Q1 Materials Science (miscellaneous) 2024 Q2 9.0 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Comech, María Paz Universidad de Zaragoza (orcid)0000-0002-4133-7553 Prada Hurtado, Anibal Antonio Olivan, Miguel Angel López Cortón, David Rodríguez Castillo, Carlos 5009 535 Universidad de Zaragoza Dpto.
