Anomaly indicators for Kaplan turbine components based on patterns of normal behavior
This paper describes and proposes some indicators for continuous monitoring of anomalous conditions in the hydraulic system of a Kaplan turbine using SCADA data. The indicators are based on significant deviations between the estimated values for key variables describing the current working condition...
A Bayesian network based approach for integration of condition-based maintenance in strategic offshore wind farm O&M simulation models
In the overall decision problem regarding optimization of operation and maintenance (O&M) for offshore wind farms, there are many approaches for solving parts of the overall decision problem. Simulationbased strategy models accurately capture system effects related to logistics, but model condit...
MonitorX - Experience from a Norwegian-Swedish research project on industry 4.0 and digitalization applied to fault detection and maintenance of hydropower plants
Operation and Maintenance Modelling
Operational expenditure (OPEX) is one of the major contributors to the levelized cost of energy (LCoE) for offshore wind farms. To assess different solutions and select the best ones, good models for maintenance and logistics decision support are required. This chapter provides an overview of, and a...
