DIGITAL MODERNIZATION OF GAS TURBINE CONTROL SYSTEMS FOR IMPROVING RELIABILITY AND OPERATIONAL PERFORMANCE IN OIL AND GAS PIPELINE INFRASTRUCTURE

Gas turbine driven compressor stations are indispensable to long distance oil and gas transmission, yet aging control platforms can restrict reliability, observability, and operational flexibility. This review evaluates how digital modernization of turbine governing, machinery protection, supervisory control, and condition monitoring can improve station performance without weakening safety functions. Thirty peer reviewed studies published between 2021 and 2025 were selected through a transparent, topic focused search of journal and publisher records, with digital object identifiers checked against discoverable publication pages.Evidence was synthesized across control architecture, fault diagnosis, digital twins, compressor interaction, cyber resilience, and maintenance planning. The reviewed work indicates that improved instrumentation and context aware diagnostics can expose degradation earlier, while constrained supervisory optimization can stabilize transitions and reduce avoidable compression energy. However, predictive accuracy does not necessarily imply useful fault sensitivity, and simulation findings rarely demonstrate equivalent benefits in continuous pipeline service. A layered modernization framework is developed that retains independent protective functions, validates signal quality, limits optimization authority, and measures outcomes against operational baselines.
