ACTIA Energy continues the deployment of its PAS9035 – Satellite Controlled Substation, with a fifteenth successful commissioning on La R\u00e9union Island for EDF SEI Insular Energy Systems<\/a>, in collaboration with OMEXOM<\/a>. This new stage is part of an electrical infrastructure modernization program that began in 2015, with the aim of strengthening the reliability of La R\u00e9union’s island network. <\/p>\n

The PAS9035 is a high-capacity RTU (Remote Terminal Unit), capable of controlling over 1000 wired data points in a single 6U rack. It integrates perfectly with the control system used by EDF SEI, using redundant IEC 101 and IEC 104 protocols, thus ensuring compatibility with current remote supervision and control standards. For more modest infrastructures, system configuration and deployment can be carried out using the Substation Interface Calculator (CIP9035)<\/a> solution. <\/p>\n

A Key Device for Island Networks<\/h2>\n

La R\u00e9union’s electrical grid, isolated from the mainland, imposes specific requirements: it must operate autonomously while integrating multiple production sources. Unlike mainland networks, substations must manage both EHV and HV, and be able to control their various production means: <\/p>\n
