A Markovian jump system approach for the estimation and adaptive diagnosis of decreased power generation in wind farms
The Institution of Engineering and Technology (IET) (2019-08-30)In this study, a Markovian jump model of the power generation system of a wind turbine is proposed and the authors present a closed-loop model-based observer to estimate the faults related to energy losses. The observer ... -
Banks of estimators and decision mechanisms for pitch actuator and sensor FE in wind turbines
Elsevier (2018-08-29)Wind turbines are prone to multiple different faults and input observability conditions are not always guaranteed for these faults. In such cases, it is not possible to build estimators which provide appropriate fault ... -
Effect of wind turbine converter control on wind power plant harmonic response and resonances
The Institution of Engineering and Technology (2017-02)Wind turbine harmonic emissions due to power electronics are a well-known power quality concern in wind power plants (WPPs). This problem may be increased by resonances because they amplify harmonic distortion around ... -
Module 4: Small wind energy
University "Vasile Alecsandri" of Bacau (2016)To start this module it is necessary an introductive part about the use of wind energy to produce electricity. There are presented historical data of wind energy use, the evolution in time of wind turbines, basic constructive ... -
Multiobjective performance-based designs in fault estimation and isolation for discrete-time systems and its application to wind turbines
Taylor & Francis (2019-04-09)In this work, we develop a performance-based design of model-based observes and statistical-based decision mechanisms for achieving fault estimation and fault isolation in systems affected by unknown inputs and stochastic ...
