Book Synopsis Control Design and Analysis of Doubly-fed Induction Generator in Wind Power Application by : Shukul Mazari
Download or read book Control Design and Analysis of Doubly-fed Induction Generator in Wind Power Application written by Shukul Mazari and published by . This book was released on 2009 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work presented in this thesis includes control system design, analysis and grid synchronization of a DFIG (doubly-fed induction generator) driven by a wind turbine using stator-voltage and stator-flux oriented frames. The DFIG is a special type of induction machine which is comprised of two back-to-back converters. One converter connects the DFIG stator to the grid, and the second converter is connected to the rotor of the machine through a DC-link capacitor. In this work, DFIG steady-state and transient models have been created in the d-q reference frame. The steady-state model is used to obtain the relationship between the rotor d-q currents and stator real/reactive power references in a particular orientation frame. The transient model is used to develop the DFIG power control mechanisms. The wind turbine driving torque is modeled by considering typical wind turbine aerodynamic characteristics under variable wind and pitch angle conditions. Comparisons are made to evaluate the differences between DFIG current/power controller in stator-voltage and stator-flux oriented frames. A speed control system has been designed to analyze maximum energy extraction from a DFIG for a particular wind speed. Lastly, the grid synchronization control technique and synchronization method have been proposed as this system requires some care during the machine start-up and integration with the grid. The main aim of the synchronization control process is to avoid heavy start-up currents and mechanical stresses on the turbine shaft and other integrated components. This is achieved by properly matching the phase angle, frequency, and magnitude of the grid voltage and the stator induced voltage irrespective of whether it is a stator-voltage or stator-flux oriented frame used for modeling the generator. Instead of a traditional control scheme using a PLL (phase-locked loop), the rotor d-q reference current is generated with grid voltage as the reference so as to induce identical voltage in the stator as that of the grid. The machine is started by a driving torque and the switch between stator and the grid can be closed for synchronization. However, appropriate timing of switch closure plays a critical role in satisfying the magnitude condition of synchronization. Simulation models have been developed using Matlab®/Simulink® for a GE 1.5 MW generator.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "After decades of development, the wind energy industry is now supplying 10 to 20% of power in electric utilities. At present Doubly-Fed Induction Generators (DFIG) are one of the most widely used generators in wind farms. The research of this thesis advances the methods of controlling DFIGs by presenting: (i)a non-mechanical (sensorless) method of determining accurate rotor speed and rotor position which are essential in implementing decoupled P-Q control; (ii)a method of autonomous frequency control whereby an islanded wind farm does not have to shut down but continues to operate as standby ready to assist the utility grid in fast restoration; (iii) a method of mitigating the problem of power imbalance at the initial period of islanding by using pitch control to spill excess wind power.The thesis also examines what economical adaptation is required to make the Doubly-Fed Induction Generator, which has the advanced controllers designed for wind power application, marketable as Doubly-Fed Induction Motor. Research is based on theoretical analysis, validated by digital simulation. A prototype DFIG 5hp experimental platform, which has been built and tested, provides experimental verification to claims." --

Book Synopsis Linear Quadratic Regulator Design for Doubly Fed Induction Generator Using Singular Perturbation Techniques by : Abhiramy Aravinthan
Download or read book Linear Quadratic Regulator Design for Doubly Fed Induction Generator Using Singular Perturbation Techniques written by Abhiramy Aravinthan and published by . This book was released on 2012 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doubly fed induction generators (DFIG) are widely used in wind power generation because of their ability to be operated at varying rotational speeds while producing power output at a constant frequency. Electrical dynamics of a DFIG is modeled using field oriented control and represented as fourth order system. This fourth order dynamics exposes a two-time scale behavior. Using singular perturbation techniques the time scales can be separated as slow and fast subsystems. Feedback control schemes can be designed and the closed-loop stability of each model can be compared. In this work, a linear quadratic feedback controller is designed for the DFIG electrical dynamics using exact, reduced order and composite models. The performances of the closed loop models are compared based on the system cost. The robustness and reliability of the control schemes are analyzed for each controller designs based on the nominal system. Based on the analysis and results, the reduced order controller performance is equally as good as the exact and composite designs during steady state operations.

This book was released on 2019-02-07 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents advanced studies on the conversion efficiency, mechanical reliability, and the quality of power related to wind energy systems. The main concern regarding such systems is reconciling the highly intermittent nature of the primary source (wind speed) with the demand for high-quality electrical energy and system stability. This means that wind energy conversion within the standard parameters imposed by the energy market and power industry is unachievable without optimization and control. The book discusses the rapid growth of control and optimization paradigms and applies them to wind energy systems: new controllers, new computational approaches, new applications, new algorithms, and new obstacles.
Book Synopsis Bit-stream Control of Doubly Fed Induction Generators by : Jonathan Bernard Bradshaw
Download or read book Bit-stream Control of Doubly Fed Induction Generators written by Jonathan Bernard Bradshaw and published by . This book was released on 2012 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years rising energy costs and concerns about global climate change have led to the widespread development of renewable electricity generation technology, especially wind generation. The Doubly Fed Induction Generator (DFIG) is commonly used for wind generation applications as it allows for efficient operation of the wind turbine by varying the speed of the generator without resorting to the use of large power converters. A typical DFIG system employs a wound rotor induction generator, with a stator that is directly connected to an external AC grid. The rotor winding is connected to the AC grid via a pair of back-to-back power converters: the Rotor Side Converter (RSC) and Grid Side Converter (GSC). The RSC and GSC require separate vector control systems. Traditionally, these control systems are implemented using microcontrollers, which perform the required control functions sequentially. As the complexity of control algorithms increases to achieve improved functionality and the time available to complete the calculations reduces to keep pace with ever-faster power electronic devices, microprocessor based solutions cannot execute the control program within the available time limit. A potential solution to this performance limitation is the use of hardware based control systems, which can execute control algorithms extremely quickly because many operations are processed in parallel. This is attractive for use in control systems, but implementing hardware control systems is difficult. The designer must either manually translate the control algorithm into individual operations, which are then usually encoded using a Hardware Description Language (HDL), or employ an automated code generation tool. The code is then synthesised and used to program a Field Programmable Gate Array (FPGA). An alternative method for implementing digital control systems is the Bit-Stream control technique. In contrast to the usual methods of implementing digital controllers, Bit-Stream control systems are developed using standard schematic editors provided by FPGA manufacturers. Provided that the desired control functions are available in the Bit-Stream library, the designer need not use HDL to develop the control system. A Bit-Stream based control system for a 2.6 kW DFIG is proposed in this thesis. As previously published research on Bit-Stream control systems focused on scalar control systems only, new Bit-Stream blocks are developed for use in vector control systems. The new vector control blocks include: coordinate transformation units, a Phase Locked Loop (PLL) and a family of modulators which convert Bit-Stream reference signals to gate drive commands for three-phase inverters. A Bit-Stream control system for a 2 kW GSC is developed, simulated and tested experimentally. Elements of this control system are adapted and re-used to develop a Bit-Stream based control system for the RSC of a 2.6 kW DFIG system. These are the first Bit-Stream based vector control systems to be reported in the literature. Supervisory control systems are added to the GSC and RSC to provide closed-loop speed control of the generator speed, soft synchronisation of the generator to the AC grid and operation with unity power factor at the stator terminals of the generator. Control of the DFIG is demonstrated by simulation and experimental testing of a 2.6 kW DFIG system.
