Système automatisé de gestion d'énergie : une approche économique pour une plus grande fiabilité opérationnelle

Motor Oil Hellas Corinth Refineries S.A. (MOH) — Agii Theodori, Corinthe, Grèce Alors que les consommateurs d'énergie, qu'il s'agisse de gros industriels, d'entreprises commerciales ou d'organismes gouvernementaux, sont en quête de systèmes d'alimentation en énergie électrique plus fiables et plus efficaces, la production d'énergie électrique en collocation (p. ex. îlots d'énergie) devient de plus en plus prisée. Le nombre de générateurs individuels sur site étant à la hausse, le besoin de moyens plus puissants pour surveiller et optimiser la production d'énergie et la gestion de la charge se fait de plus en plus ressentir. Les systèmes automatisés de gestion d'énergie dotés d'une technologie intégrée, tels que les systèmes de délestage et de régulation de la production à haute vitesse, ont fait leurs preuves pour répondre à ce besoin.

Making the Switch—How One Utility Is Transitioning Seamlessly From Leased Analog to Ethernet

North American electric utilities have long relied on analog leased telecom services for deterministic, low-latency communication for critical protection schemes. However, telecom carriers have begun to discontinue analog, and most digital alternatives offer neither the guaranteed latency nor the synchronous performance required for protection applications. Learn how Consumers Energy, an Michigan-based electric utility, effectively migrated from leased analog to digital circuits for their DTT and POTT schemes while still meeting strict latency, determinism, and asymmetry requirements.
