Fault Detection and Prediction in Smart Grids
(Chapter, 2018)Modern society is to a larger and larger extent dependant on electric energy, and hence the reliance on and utilization of the electric grid is increasing steadily. At the same time the production and consumption patterns ... -
Fault Detection for Position Mooring Using Statistical Analysis
(Master thesis, 2018)The standard approach for detecting mooring line failures for position moored vessels is by measuring the tension in the mooring lines, either directly or indirectly. The sensors measuring the line tensions are often hard ... -
Fault detection in glucose control: Is it time to move beyond CGM data?
(Journal article; Peer reviewed, 2018)People with diabetes mellitus type 1 could benefit from fully automated systems for glucose control. However, faults in any component of the system can severely compromise the safety of the user. An increasing degree of ... -
Fault Detection of Drive Trains in 10 MW Offshore Wind Turbines using Non-Traditional Methods
(Master thesis, 2020)One of the world’s biggest concerns is global warming, a solution to this can be wind energy. Offshore wind energy has advantages over onshore wind energy, however, the levelized cost of energy is higher. The maintenance ... -
Fault Detection of Offshore Wind Turbine Drivetrain, State-of-the-Art, Development Trend and Role of Digital Twin

Fault detection of offshore wind turbine drivetrains in different environmental conditions through optimal selection of vibration measurements
(Peer reviewed; Journal article, 2023)In this study, a vibration-based fault detection method is proposed for offshore wind turbine drivetrain based on the optimal selection of the acceleration measurements. The main aim is to find the sensor positions mounted ... -
Fault Detection with LSTM-Based Variational Autoencoder for Maritime Components
(Journal article; Peer reviewed, 2021)Maintenance routines on ships today follow either a reactive maintenance (RM) or preventive maintenance (PvM) approach. RM can be regarded as post-failure repair, which might create large costs. PvM uses predetermined ... -
Fault Detection, Localization and Clearance for MMC based on Indirect Finite Control Set Model Predictive Control
(Chapter, 2023)In this paper, indirect finite control set model predictive control (I-FCS-MPC) is used for detecting, localizing, and tolerating open-circuit failures in the transistors without the use of arm voltage sensors. The fault ... -
Fault diagnosis of downhole drilling incidents using adaptive observers and statistical change detection
(Journal article; Peer reviewed, 2015)Downhole abnormal incidents during oil and gas drilling cause costly delays, and may also potentially lead to dangerous scenarios. Different incidents will cause changes to different parts of the physics of the process. ... -
