This paper presents a coordinated feedback linearization strategy (CFLS) for DC-based doubly-fed induction generator (DFIG) system to track the maximum power point. The stator and rotor of DFIG are connected to DC grid directly by two voltage source converters. Compared with a traditional DFIG system, the DC-based DFIG system has more system inputs and coupling, which increases the difficulty of vector control strategy. Accordingly, CFLS is proposed to make DFIG operate at the maximum power point (MPP), and two aspects are improved: first a single-loop control is adopted to make DFIG operate steady and accurate under coordinated the control of RSC and SSC. Second system control laws are obtained by the feedback linearization strategy that achieves DC-based DFIG system decoupling fully during the MPPT and system control. Simulations are carried out the comparison between CFLS and conventional vector control (VC), and it shows that the control performance of CFLS is superior.

This paper presents a fault-tolerant Voltage Source Converter (VSC) for Field Oriented Control (FOC) of a stand-alone Doubly Fed Induction Generator (DFIG) connected to a DC load. In the proposed topology, the stator of the DFIG is connected to a DC load through a diode rectifier, while the rotor is connected to the DC load through a VSC. This topology allows the integration of DFIG in the hybrid system with other sources of production and storage, such as photovoltaic system, connected to the same DC bus. The fault-tolerant VSC consists in incorporating a fourth leg to replace the faulted leg. A fault detection scheme for switch device open-circuit faults is proposed in this study. The novelty of this method consists in analyzing the rotor currents within normal and faulty operating modes. Simulation results are presented for a 3.7[Formula: see text]kW DFIG-DC system with single open-circuit faults that validate the methods presented in this study. The effectiveness of the proposed fault detection method has been validated experimentally by using dSpace DS1104 control board based on TMS320F240 real time Digital Signal Processor (DSP).

With the increase in doubly fed induction generator-based wind energy conversion systems (DFIG-WECS) worldwide, improving the fault ride-through (FRT) capability of the entire system has been given much attention. Enhancement of the FRT capability of a DFIG-WECS is conventionally realized by employing a flexible AC transmission system device with a proper control system. This paper presents a non-conventional method for the improvement of the FRT of DFIG-WECS, using a high-temperature superconducting coil interfaced with the DC-link of the rotor and stator side converters through a DC-chopper. A fractional-order proportional-integral (FOPI) controller is utilized to regulate the DC-chopper duty cycle in order to properly manage the power flow between the DC-link and the coil. Two optimization techniques, Harmony Search and Grey Wolf Optimizer, are employed to determine the optimum size of the superconducting coil along with the optimum parameters of the FOPI controller. The effectiveness of the two proposed optimization techniques is highlighted through comparing their performance with the well-known particle swarm optimization technique.

This paper proposes a non-superconducting bridge-type fault current limiter (BFCL) as a potential solution to the fault problems of doubly fed induction generator (DFIG) integrated voltage source converter high-voltage DC (VSC-HVDC) transmission systems. As the VSC-HVDC and DFIG systems are vulnerable to AC/DC faults, a BFCL controller is developed to insert sizeable impedance during the inception of system disturbances. In the proposed control scheme, constant capacitor voltage is maintained by the stator VSC (SVSC) controller, while current extraction or injection is achieved by rotor VSC (RVSC) controller. Current control mode-based active and reactive power controllers for an HVDC system are developed. Balanced and different unbalanced faults are applied in the system to show the effectiveness of the proposed BFCL solution. A DFIG wind-based VSC-HVDC system, BFCL, and their controllers are implemented in a real time digital simulator (RTDS). The performance of the proposed BFCL control strategy in DFIG-based VSC-HVDC system is compared with a series dynamic braking resistor (SDBR). Comparative RTDS implementation results show that the proposed BFCL control strategy is very efficient in improving system fault ride through (FRT) capability and outperforms SDBR in all cases considered.

<p>This paper deals with the interconnected grid hybrid renewable energy system (HRES). The wind energy conversion system (WECS), is built around a wind turbine coupled to a doubly fed induction generator (DFIG). The stator of DFIG is directly related to the grid and the rotor is connected to the grid through back-to-back power converters. The proposed algorithm combines the nonlinear Backstepping approach and the eld orientation applied to control the DFIG. In a rst step, this technique is applied to the side converter rotor (RSC), to control the electromagnetic torque and reactive power, and secondly, it is applied to the grid side converter (GSC) to control the power exchanged with the grid and regulate the DC bus voltage. The PV energy system is composed by the PV array and the DC-DC boost converter which controlled by the MPPT method to extract the optimal power. Simulations results present the performances in terms of set point tracking, stability, and robustness with respect to the variation in wind speed and irradiation.</p>

The use of doubly fed induction generators (DFIGs) in wind turbines has become quite common over the last few years. DFIG wind turbine is an integrated part of distributed generation system. This paper presents a Fuzzy based controller SMES unit in DFIG for improving the ac output on grid side. The excitation system is composed of the rotor-side converter, the grid-side converter, the dc chopper and the superconducting magnet. The superconducting magnet is connected with the dc side of the two converters, which can handle the active power transfer with the rotor of DFIG and the power grid independently, even thou Sutton small fluctuations are occur in active power on AC side. For smoothening the AC output power waveform a Fuzzy based controller is introduced in SMES controller unit, which implemented using simulation developed in MATLAB/ SIMULINK 7.2 version. The model of the FUZZY controlled SMES based excitation system for DFIG is established, and the simulation tests are performed to evaluate the system performance.

<p>This article proposes a novel scheme to improve the doubly-fed induction generator (DFIG) behavior during grid fault. The DFIG’s are sensitives to voltage variations when abrupt variations of the wind velocity arrive. For enhancing DFIG behavior, protecting the converters, and smoothing the fluctuations power output of the DFIG under sag voltage; a novel hybrid energy storage system scheme and its controller are proposed. The main advantages of our approach are a faster response and suppressing overvoltage on DC bus and globally less stress in the storage system. The control structure decreases the tiredness on the battery and restores the DC bus voltage rapidly, globally the battery system operating time increases. The results obtained by simulations in MATLAB validate the benefits of the suggested control.</p>

A grid connected doubly-fed induction generator (DFIG) system, driven by variable speed wind turbine is considered in this research to satisfy grid code requirements. Remaining grid synchronized and stable under voltage sag and voltage swell, obtaining power control through dc link voltage control, and providing unity power factor at grid terminals are the achievements. The DFIG system uses two back-to-back converters. Vector control strategy is used with the grid side and rotor side converters, and taken up for research for further improvement. The grid side converter controls dc-link voltage and maintains unity power factor at the grid connection point. The rotor side converter supplies the reactive power of the machine and maintains the speed constant irrespective of the transient behavior of the grid. In this paper the behavior of the DFIG system is analyzed under grid voltage fluctuation and the experimental results are obtained using RT-LAB. Main contribution of this work is in improving the DFIG system performance with grid low voltage and over voltage ride through capability through simulation, and its real time experimental verification.

This article addresses the problem of controlling an overall wind energy conversion system (WECS) formed by a wind turbine connected to the grid via a doubly fed introduction generator (DFIG) and an AC/DC/AC converter. The main control objectives are fourfold: (i) designing an output feedback speed controller that makes the DFIG rotate at the optimal value delivered by the MPPT strategy, (ii) controlling the stator reactive power so as to be null, (iii) guaranteeing the DC-link voltage in the grid side converter to be at a given constant value, (iv) ensuring a unitary power factor. A high gain observer is synthesized, in order to provide estimated values of the mechanical variables. To achieve the control objectives, a sliding mode controller involving the mechanical observer is designed. The performance of the system configuration based on the 2MW-DFIG with the proposed controller is evaluated by a numerical simulation under a realistic wind profile using MATLAB/SIMULINK/SimPowerSystems environment.

This paper presents the design, modeling, simulation and the experimental implementation of a 1.5 kW relatively low-cost wind energy conversion system (WECS) based on the double fed induction generator (DFIG) configuration. In the preliminary experiments, we test the DFIG power control under fixe speed by applying the vector control principle, then we insert the physical emulator presented in the controlled DC motor in order to simulate the static-dynamic behaviors of a real wind turbine with the use of the Tip Speed Ratio TSR based MPPT algorithm to extract the maximum available power on the emulator. The proposed structure is simulated using MATLAB Simulink environment, the obtained results are validated experimentally on our laboratory setup. We also develop an application with MATLAB AppDesigner that calculates the operating point of our system at steady state and visualize the power transfer, current, voltage and electromagnetic torque values of the DFIG and the DC motor before starting the stimulation or the experimental manipulation. The MPPT, the DC motor control and the DFIG power control algorithms are implanted in C, embedded on a dSPACE DS1104 control board. The obtained results confirm the reliability of the proposed WECS to manage all the probable operating modes, also the effectiveness of the physical simulator in the role of wind turbine emulation.

Les convertisseurs statiques triphasés AC/DC/AC à structure tension sont largement utilisés dans de nombreuses applications de puissance. La continuité de service de ces systèmes ainsi que leur sécurité, leur fiabilité et leurs performances sont aujourd'hui des préoccupations majeures de ce domaine lié à l'énergie. En effet, la défaillance du convertisseur peut conduire à la perte totale ou partielle du contrôle des courants de phase et peut donc provoquer de graves dysfonctionnements du système, voire son arrêt complet. Afin d'empêcher la propagation du défaut aux autres composants du système et assurer la continuité de service en toute circonstance lors d'une défaillance du convertisseur, des topologies de convertisseur "fault tolerant" associées à des méthodes efficaces et rapides de détection et de compensation de défaut doivent être mises en oeuvre. Dans ce mémoire, nous étudions la continuité de service de trois topologies de convertisseurs AC/DC/AC avec ou sans redondance, lors de la défaillance d'un de leurs interrupteurs. Deux applications sont ciblées : l'alimentation d'une charge RL triphasée et un système éolien de conversion de l'énergie basé sur une MADA. Un composant FPGA est utilisé pour la détection du défaut, afin de réduire autant que possible son temps de détection. Des variantes permettant d'optimiser la méthode de détection de défaut sont également proposées et évaluées. Les trois topologies de convertisseurs proposées, associées à leurs contrôleurs, ont été validées de la modélisation/ simulation à la validation sur banc de test expérimental, en passant par le prototypage "FPGA in the Loop" du FPGA, destiné plus spécifiquement à la détection du défaut
AC/DC/AC converters are widely being used in a variety of power applications. Continuity of service of these systems as well as their reliability and performances are now of the major concerns. Indeed, the failure of the converter can lead to the total or partial loss of the control of the phase currents and can cause serious system malfunction or shutdown. Thus, uncompensated faults can quickly endanger the system. Therefore, to prevent the spread of the fault to the other system components and to ensure continuity of service, fault tolerant converter topologies associated to quick and effective fault detection and compensation methods must be implemented. In this thesis, we present the continuity of service of three AC/DC/AC fault tolerant converters with or without redundancy, in the presence of a fault in one of their switches. Two types of applications are studied: the supply off a three-phase charge and a wind energy conversion system based on a DFIG. An FPGA based implementation is used for fault detection, in order to reduce the detection time as much as possible. Three optimizations in the fault detection method are also presented. During these researches, the three proposed converter topologies and their controllers are validated in simulations and also experimentally, while being validated in a "FPGA in the Loop" prototyping

Wind turbine modelling using doubly-fed induction generators is a well-known subject. However, studies have tended to focus on optimising the components of the system rather than considering the interaction between the components. This research examines the interaction of the control methods for a doubly-fed induction generator (DFIG) in a wind turbine application integrating them with the crowbar protection control and DC-link brake control to make the best use of the converter. The controls of the rotor-side and the grid-side converters of the DFIG model are both well established and have been shown to work. Typically the crowbar protection is designed in order to protect the rotor-side converter and the power electronic components of the DFIG system from high currents occurring in the rotor due to the faults. The DC-link brake-overvoltage protection is also designed to prevent the overcharging of the DC-link capacitor placed between the rotor-side converter and the grid-side converter. In order to show that these protection schemes work and with thought can co-ordinate with each other, tests consisting of a number of balanced three-, two- and one-phase voltage sags are applied to the network voltage. The main contributions of this thesis are establishing operational tuning and design limits for the controllers and system subassemblies. This is to minimise the electrical subsystem interaction while maintaining adequate performance, and have an improved DC-link control. This work also includes a full electrical system study of the wind turbine and an essential literature review on significant references in the field of the DFIG wind turbine system modelling, control and protection. Specifically this research project makes a number of novel contributions to the literature: enhanced DC voltage control including operating point sensitivity analysis and dynamic stiffness assessment, sensitivity and robustness analyses of the power loop control and control loop segmentation by appropriately tuning the controller loops.

In recent years, wind energy has become one of the most important and promising sources of renewable energy, which demands additional transmission capacity and better means of maintaining system reliability. The evolution of technology related to wind systems industry leaded to the development of a generation of variable speed wind turbines that present many advantages compared to the fixed speed wind turbines. These wind energy conversion systems are connected to the grid through Voltage Source Converters (VSC) to make variable speed operation possible. The studied system here is a variable speed wind generation system based on Doubly Fed Induction Generator (DFIG). The stator of the generator is directly connected to the grid while the rotor is connected through a back-to-back converter which is dimensioned to stand only a fraction of the generator rated power. To harness the wind power efficiently the most reliable system in the present era is grid connected doubly fed induction generator. The DFIG brings the advantage of utilizing the turns ratio of the machine, so the converter does not need to be rated for the machine’s full rated power. The rotor side converter (RSC) usually provides active and reactive power control of the machine while the grid-side converter (GSC) keeps the voltage of the DC-link constant. The additional freedom of reactive power generation by the GSC is usually not used due to the fact that it is more preferable to do so using the RSC. However, within the available current capacity the GSC can be controlled to participate in reactive power generation in steady state as well as during low voltage periods. The GSC can supply the required reactive current very quickly while the RSC passes the current through the machine resulting in a delay. Both converters can be temporarily overloaded, so the DFIG is able to provide a considerable contribution to grid voltage support during short circuit periods. This report deals with the introduction of DFIG, AC/DC/AC converter control and finally the SIMULINK/MATLAB simulation for isolated Induction generator as well as for grid connected Doubly Fed Induction Generator and corresponding results and waveforms are displayed.

Στις μέρες μας οι συνεχώς αυξανόμενες ενεργειακές ανάγκες, καθώς και η απαίτηση των κοινωνιών για ένα πιο καθαρό περιβάλλον, έχουν κάνει τις ανανεώσιμες πηγές ενέργειας όλο και πιο ελκυστικές ως προς την εκμετάλλευση τους. Η αξιοποίηση της αιολικής ενέργειας στην παραγωγή ηλεκτρικής ενέργειας κερδίζει όλο και περισσότερο έδαφος. Η τεχνολογία των αιολικών συστημάτων αναπτύσσεται συνεχώς ,με αποτέλεσμα να υπάρχουν διάφορες κατηγορίες αυτών, ανάλογα με τη χρήση για την οποία προορίζονται. Στην παρούσα διπλωματική μου εργασία, μελετάται ένα αιολικό σύστημα μεταβλητών στροφών που χρησιμοποιεί μία παραλλαγή της επαγωγικής μηχανής Διπλής Τροφοδοσίας. Η διαφοροποίηση του έγκειται στον επιπλέον dc/ac μετατροπέα που χρησιμοποιείται, προκειμένου να ελέγξουμε την τάση που μπορεί να δει ο στάτης. Μ΄ αυτό τον τρόπο, το αιολικό σύστημα μιας γεννήτριας διπλής τροφοδοσίας γίνεται ακόμα πιο αξιόπιστο, συνεχίζοντας την παραγωγή ισχύος και παραμένοντας συνδεδεμένο με το δίκτυο σε περίπτωση σφάλματος στην πλευρά του δικτύου. Στη μελέτη αυτή, αφού εξαγάγαμε το μαθηματικό μοντέλο του συστήματος και το προσομοιώσαμε σε περιβάλλον Matlab - Simulink, δοκιμάσαμε το σύστημα σε συνθήκες ύπαρξης σφάλματος στο δίκτυο. Στο σύστημα εφαρμόστηκαν κλασικές τεχνικές ελέγχου,με στόχο τη διατήρηση της μέγιστης απομάστευσης ισχύος από το σύστημα, την αύξηση της αντοχής του σε σφάλματα από την πλευρά του δικτύου, καθώς και τη μη αποσύνδεση του συστήματος από το δίκτυο σε μία τέτοια περίπτωση. Τέλος, συγκρίναμε τη συμπεριφορά αυτού του συστήματος με τη συμπεριφορά ενός κλασικού αιολικού συστήματος με επαγωγική γεννήτρια Διπλής Τροφοδοσίας και παραθέσαμε τις διαφορές.
The increasingly energy demands in our days and also the modern societies demand for a greener environment, have made the electrical energy production from renewable energy sources more attractive. The use of wind energy in the electrical energy production is having more and more fervent supporters. The technology and the types of the wind systems varies, depending on the use and the environmental conditions. In my diploma thesis I designed, we will study a variation of a wind system with a variable speed operation with a Doubly Fed Induction Generator. In this system we also use a dc/ac converter in order to control the voltage which the stator can “see”. Using this converter the wind system with a DFIG is more reliable and remains connected to the ac grid, maintaining the maximum power production, in case of a fault on grid side. In this thesis, after we made the mathematical model with a great accuracy and simulated using Matlab - Simulink, we tested it under conditions of different voltage sags from the side of the grid. In order to control the system and maintaining the power production power at the maximum level, we used classic control methods, and as a result, we achieved to keep the maximum level of power production and to keep the wind system connected to the grid in a scenario of a grid side fault. Finally, we compared the behavior of the system we designed with the wind system with the classic DFIG and we presented the differences.

Doubly-fed induction generator wind turbines are largely developed due to their variable speed feature. The response of wind turbines to grid disturbance is an important issue, especially since the rated power of the wind turbine is increased; therefore, it is important to study the effect of grid disturbances on the wind turbine. In the chapter, the characteristics of the doubly-fed induction generator during wind speed fluctuation are studied. MATLAB/Simulink software has been used to observe the characteristics of wind turbines during wind speed fluctuation. Simulation results of the doubly-fed induction generator wind turbine system show improved system stability during wind speed variation. Power electronics converters used in the DFIG system are the most sensitive parts of the variable speed wind turbines with regards to system disturbances. To protect from excessive current, the DFIG system is equipped with an over-current and DC voltage overload protection system that trips the system under abnormal conditions.
