ENHANCING ALARM MANAGEMENT IN GREEN HYDROGEN PLANTS: A COMPREHENSIVE ANALYSIS OF THE V-NETS-BASED METHODOLOGY PLANTS. C.T.F Cienc. Tecnol. Futuro [online]. 2024, vol.14, n.2, pp.15-28.  Epub 04-Ago-2025. ISSN 0122-5383.  https://doi.org/10.29047/01225383.736.

This paper presents a novel V-nets-Based Alarm Management (VBAM) methodology designed to enhance supervision and safety in Green Hydrogen Plants (GHPs). The proposed approach integrates visual modeling and temporal pattern analysis to accurately detect and manage alarms, seeking to reduce false positives and optimize response times. The methodology starts with a Preliminary Hazard and Operability (HAZOP) analysis to identify potential hazards and critical operational conditions, which are the foundation for constructing V-nets that map the temporal relationships between discrete events. By systematically capturing event sequences and their interdependencies, the VBAM approach allows for early fault detection and a proactive alarm management system fit for varying operational scenarios. A case study of the EL30N Green Hydrogen Plant proves the efficacy of the VBAM methodology in reducing downtime, improving system safety, and enhancing overall operational efficiency. This work provides a comprehensive framework for addressing discrete event challenges in alarm management, paving the way for safer and more resilient practices in green hydrogen production. Future directions will include expanding the application of VBAM to other operational phases and incorporating real-time analytics for further performance optimization.
