Condition monitoring of spar‐type floating wind turbine drivetrain using statistical fault diagnosis
(Journal article, 2018)Operation and maintenance costs are significant for large‐scale wind turbines and particularly so for offshore. A well‐organized operation and maintenance strategy is vital to ensure the reliability, availability, and ... -
Response analysis and comparison of a spar-type floating offshore wind turbine and an onshore wind turbine under blade pitch controller faults
(Journal article; Peer reviewed, 2016)This paper analyses the effects of three pitch controller faults on the responses of an onshore wind turbine and a spar-type offshore floating wind turbine. These faults include: a stuck blade pitch actuator, a fixed value ... -
Steady and transient inflow dynamics with actuator disk vortex theory
(Journal article; Peer reviewed, 2018)The actuator disk is a well‐known and widely used theoretical tool in wind engineering. This work proposes a new theory based on an actuator surface, capable of treating time‐varying vectorial load distributions and yaw/pitch ... -
Wind farm voltage dip measurements
(Journal article; Peer reviewed, 2014)This paper is based on continuous measurements of voltages and currents from three wind farms for a period of 1 year, and the focus is on voltage dips. The purpose is to get an overview of the characteristics and rate of ...
