Title: Detecting and diagnosing disturbances in oil and gas processes and the electrical supply using advanced signal analysis
Authors: Cecílio, IM
Item Type: Conference Paper
Abstract: Industrial processes can be upset by disturbances which compromise their safety, energy-efficiency and production, and in the worst cases can lead to catastrophic incidents. The purpose of this work is developing new signal analysis techniques which enable the early detection and diagnosis of such disturbances. The focus is on sites which process natural gas and supply the Western Europe and the UK. These are typically huge installations and critical to the European infrastructure. The novelty of this work is to analyze process signals together with signals from the electrical supply. The interaction with the electrical supply, which is rapidly gaining importance in Europe and in the UK, opens up new research questions in signal analysis. A new technique proposed addresses the detection of spiky disturbances, such as the case of voltage dips. A second technique handles the case of signals with different sampling rates, which is a common situation when combining process and electrical sub-systems. The results presented provide advancement in the state-of-the-art and demonstrate in industrial case studies the extra insights that can be gained.
