Active fault tolerance control of a Wind Turbine System using an unknown input observer with an actuator fault
International Journal of Applied Mathematics and Computer Science, 2018Co-Authors: Haoping Wang, Abdel Aitouche, Yang Tian, Nicolai ChristovAbstract:AbstractThis paper proposes a fault tolerant control scheme based on an unknown input observer for a Wind Turbine System subject to an actuator fault and disturbance. Firstly, an unknown input observer for state estimation and fault detection using a linear parameter varying model is developed. By solving linear matrix inequalities (LMIs) and linear matrix equalities (LMEs), the gains of the unknown input observer are obtained. The convergence of the unknown input observer is also analysed with Lyapunov theory. Secondly, using fault estimation, an active fault tolerant controller is applied to a Wind Turbine System. Finally, a simulation of a Wind Turbine benchmark with an actuator fault is tested for the proposed method. The simulation results indicate that the proposed FTC scheme is efficient.

Direct power control of DFIG Wind Turbine Systems based on an intelligent proportional-integral sliding mode control
ISA Transactions, 2016Co-Authors: Haoping Wang, Abdel Aitouche, Yang Tian, John KleinAbstract:This paper presents an intelligent proportional-integral sliding mode control (iPISMC) for direct power control of variable speed-constant frequency Wind Turbine System. This approach deals with optimal power production (in the maximum power point tracking sense) under several disturbance factors such as turbulent Wind. This controller is made of two sub-components: (i) an intelligent proportional-integral module for online disturbance compensation and (ii) a sliding mode module for circumventing disturbance estimation errors. This iPISMC method has been tested on FAST/Simulink platform of a 5 MW Wind Turbine System. The obtained results demonstrate that the proposed iPISMC method outperforms the classical PI and intelligent proportional-integral control (iPI) in terms of both active power and response time.

CCA - Recursive model free control of variable speed Wind Turbine Systems
2012 IEEE International Conference on Control Applications, 2012Co-Authors: Haoping Wang, Nicolai Christov, Adela Pintea, Pierre Borne, D. PopescuAbstract:The paper deals with the recursive model free control of horizontal variable speed Wind Turbines, which makes possible to obtain a compromise between the Wind energy limitation, the rotor speed reference tracking and the decreasing of solicitations induced in the mechanical structure of the Turbine. The Wind Turbine System dynamics is described by a multi-input multi-output nonlinear mathematical model. A recursive controller is proposed which uses only the measurement of the System output and does not require identification of Turbine parameters. The effectiveness and the robustness of the new controller are analyzed by numerical simulation.

H∞ generalized dynamic unknown inputs observer design for discrete LPV Systems. Application to Wind Turbine
European Journal of Control, 2018Co-Authors: Abraham-jashiel Pérez-estrada, Gloria-lilia Osorio-gordillo, Marouane Alma, Mohamed Darouach, Víctor-hugo Olivares-peregrinoAbstract:This paper concerns the design of a generalized dynamic observer (GDO) for unknown inputs discrete-time linear parameter varying (LPV) Systems. The structure of this observer generalizes the existing ones of the proportional observer (PO) and proportional integral observer (PIO). Conditions for the existence and stability of this observer are given through parameter dependent Lyapunov (PDL) function and its design is obtained in terms of a set of linear matrix inequalities (LMIs). The efficiency of the proposed observer, compared to particular cases of this structure, as the PO and PIO, is illustrated by a 4.8 MW Wind Turbine System.

Doubly Fed Induction Generator Wind Turbine Systems Subject to Recurring Symmetrical Grid Faults
IEEE Transactions on Power Electronics, 2016Co-Authors: Wenjie Chen, Frede Blaabjerg, Nan Zhu, Min ChenAbstract:New grid codes demand the Wind Turbine Systems to ride through recurring grid faults. In this paper, the performance of the doubly Ffed induction generator (DFIG) Wind Turbine System under recurring symmetrical grid faults is analyzed. The mathematical model of the DFIG under recurring symmetrical grid faults is established. The analysis is based on the DFIG Wind Turbine System with the typical low-voltage ride-through strategy—with rotor-side crowbar. The stator natural flux produced by the voltage recovery after the first grid fault may be superposed on the stator natural flux produced by the second grid fault, so that the transient rotor and stator current and torque fluctuations under the second grid fault may be influenced by the characteristic of the first grid fault, including the voltage dips level and the grid fault angle, as well as the duration between two faults. The mathematical model of the DFIG under recurring grid faults is verified by simulations on a 1.5-MW DFIG Wind Turbine System model and experiments on a 30-kW reduced scale DFIG test System.

IEEE Transactions on Power Electronics, 2009Co-Authors: Pedro Rodriguez, A Timbus, Remus Teodorescu, M Liserre, Frede BlaabjergAbstract:This letter aims to present a generalized vector-based formulation for calculating the grid-side current reference to control reactive power delivered to the grid. Strategies for current reference generation were implemented on the abc stationary reference frame, and their effectiveness was demonstrated experimentally, perhaps validating the theoretical analysis even under grid fault conditions.

Stability Improvement of Wind Turbine Systems by STATCOM
IECON 2006 - 32nd Annual Conference on IEEE Industrial Electronics, 2006Co-Authors: Zhe Chen, Frede BlaabjergAbstract:The development of renewable energy based generation technologies attracts more and more attention. In particularly large number of Wind Turbines are being installed and connected to power System. In some countries or networks, the penetration level of Wind power is significant high so as to affect the power System operation and control. Consequently, the stable operation of Wind Turbine Systems is very important for power System stability. This paper studies the behaviours of a Wind Turbine System and the effect of STATCOM on stability improvement. The function of the STATCOM in improving the System stability has been demonstrated.

Design methodologies for sizing a battery bank devoted to a stand-alone and electronically passive Wind Turbine System
Renewable and Sustainable Energy Reviews, 2016Co-Authors: Malek Belouda, Amine Jaafar, Bruno Sareni, Xavier Roboam, Jamel BelhadjAbstract:In this paper, the authors investigate four original methodologies for sizing a battery bank inside a passive Wind Turbine System. This device interacts with Wind and load cycles, especially for a stand-alone application. Generally, actual Wind speed measurements are of long duration which leads to extensive processing time in a global optimization context requiring a wide number of System simulations. The first part of this article outlines two sizing methodologies based on a statistical approach for the sizing of the electrochemical storage device of a stand-alone passive Wind Turbine System. Two other efficient methodologies based on the synthesis of compact Wind speed profiles by means of evolutionary algorithms are described in the second part of this paper. The results are finally discussed with regard to the relevance of the battery bank sizing and in terms of computation cost, this later issue being crucial to an Integrated Optimal Design (IOD) process.

Integrated optimal design and sensitivity analysis of a stand alone Wind Turbine System with storage for rural electrification
Renewable and Sustainable Energy Reviews, 2013Co-Authors: Malek Belouda, Amine Jaafar, Bruno Sareni, Xavier Roboam, Jamel BelhadjAbstract:In this paper, the authors investigate a robust Integrated Optimal Design (IOD) devoted to a passive Wind Turbine System with electrochemical storage bank: this stand alone System is dedicated to rural electrification. The aim of the IOD is to find the optimal combination and sizing among a set of System components that fulfils System requirements with the lowest System Total Cost of Ownership (TCO). The passive Wind System associated with the storage bank interacts with Wind speed and load cycles. A set of passive Wind Turbines spread on a convenient power range (2 - 16 kW) are obtained through an IOD process at the device level detailed in previous papers. The System cost model is based on data sheets for the Wind Turbines and related to battery cycles for the storage bank. From the range of Wind Turbines, a "System level" optimization problem is stated and solved using an exhaustive search. The optimization results are finally exposed and discussed through a sensitivity analysis in order to extract the most robust solution versus environmental data variations among a set of good solutions.

Integrated Optimal Design of a Passive Wind Turbine System: An Experimental Validation
IEEE Transactions on Sustainable Energy, 2010Co-Authors: Duc-hoan Tran, Bruno Sareni, Xavier Roboam, Christophe EspanetAbstract:This work presents design and experimentation of a full passive Wind Turbine System without active electronic part(power and control). The efficiency of such device can be obtained only if the System design parameters are mutually adapted through an Integrated Optimal Design (IOD) method. This approach based on multiobjective optimization, aims at concurrently optimizing the Wind power extraction and the global System losses for a given Wind speed profile while reducing the weight of the Wind Turbine generator. It allows us to obtain the main characteristics (geometric and energetic features) of the optimal Permanent Magnet Synchronous Generator (PMSG) for the passive Wind Turbine. Finally, experiments on the PMSG prototype built from this work show a good agreement with theoretical predictions. This validates the design approach and confirms the effectiveness of such passive device.

Model simplification and optimization of a passive Wind Turbine generator
Renewable Energy, 2009Co-Authors: Bruno Sareni, Xavier Roboam, Abdenour Abdelli, Duc-hoan TranAbstract:In this paper, the design of a "low cost full passive structure" of Wind Turbine System without active electronic part (power and control) is investigated. The efficiency of such device can be obtained only if the design parameters are mutually adapted through an optimization design approach. For this purpose, sizing and simulating models are developed to characterize the behavior and the efficiency of the Wind Turbine System. A model simplification approach is presented, allowing the reduction of computational times and the investigation of multiple Pareto-optimal solutions with a multiobjective genetic algorithm. Results show that the optimized Wind Turbine configurations are capable of matching very closely the behavior of active Wind Turbine Systems which operate at optimal Wind powers by using a MPPT control device.
