This book was released on 2016 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: The short circuit behavior of the early generation wind turbines depends solely on the physical characteristics of the machine. The conventional protection schemes can be applied to provide protection to these wind farms. But the full converter based Type 4 Wind turbine generators have complex fault current characteristics which are governed by the converter controls. The control response of the WTG's during fault is not similar to that of synchronous generators. The use of relay with conventional protection schemes may cause misoperation. In this thesis an attempt is made to explain the complex converter controls and operation and various grid codes that the wind farms are expected to follow. A new protection scheme is designed based on the system operation and tested with simulation fault responses of Type 4 wind turbine in real time digital simulator. This thesis also explains the reasons that cause misoperation for using convention protection schemes.

Download or read book Grid Integrated Type 3 Wind Systems written by Rishabh Jain and published by . This book was released on 2014 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, the line protection elements and their supervisory elements are analyzed in context of Type 3 (Doubly Fed Induction Generator based) grid integrated wind turbine systems. The underlying converter and controller design algorithms and topologies are discussed. A detailed controller for the Type 3 wind turbine system is designed and integrated to the grid using the Real Time Digital Simulator (RTDS). An alternative to the conventional Phase Locked Loop (PLL) for tracking of rotor frequency is designed and implemented. A comparative analysis of the performance of an averaged model and the corresponding switching model is presented. After completing the Wind Turbine (WT) model design, the averaged model is used to model an aggregate 10-generator equivalent model tied to a 230kV grid via a 22kV collector. This model is a great asset to understand dynamics, and the unfaulted and faulted behavior of aggregated and single-turbine Type 3 WT systems. The model is then utilized to analyze the response of conventional protection schemes (Line current Differential and Mho Distance elements) and their respective supervisory elements of modern commercial protection relays in real time by hardware-in-the-loop simulation using the RTDS. Differences in the behavior of these elements compared to conventional power systems is noted. Fault are analyzed from the relay's perspective and the reasons for the observed behavior are presented. Challenges associated with sequence components and relay sensitivity are discussed and alternate practices to circumvent these issues are recommended.
Download or read book Modeling of Wind Turbines with Doubly Fed Generator System written by Jens Fortmann and published by Springer. This book was released on 2014-08-22 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jens Fortmann describes the deduction of models for the grid integration of variable speed wind turbines and the reactive power control design of wind plants. The modeling part is intended as background to understand the theory, capabilities and limitations of the generic doubly fed generator and full converter wind turbine models described in the IEC 61400-27-1 and as 2nd generation WECC models that are used as standard library models of wind turbines for grid simulation software. Focus of the reactive power control part is a deduction of the origin and theory behind the reactive current requirements during faults found in almost all modern grid codes. Based on this analysis, the design of a reactive power control system for wind turbines and wind plants is deduced that can provide static and dynamic capabilities to ensure a stable voltage and reactive power control for future grids without remaining synchronous generation.

Download or read book Modeling and Control of Static Converters for Hybrid Storage Systems written by Fekik, Arezki and published by IGI Global. This book was released on 2021-09-17 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: The energy transition initiated in recent years has enabled the growing integration of renewable production into the energy mix. Microgrids make it possible to maximize the efficiency of energy transmission from source to consumer by bringing the latter together geographically and by reducing losses linked to transport. However, the lack of inertia and the micro-grid support system makes it weak, and energy storage is necessary to ensure its proper functioning. Current storage technologies do not make it possible to provide both a large capacity of energy and power at the same time. Hybrid storage is a solution that combines the advantages of several technologies and reduces their disadvantages. Modeling and Control of Static Converters for Hybrid Storage Systems covers the modeling, control theorems, and optimization techniques that solve many scientific problems for researchers in the field of power converter control for renewable energy hybrid storage and places particular emphasis on the modeling and control of static converters for hybrid storage systems. Covering topics ranging from energy storage to power generation, this book is ideal for automation engineers, electrical engineers, mechanical engineers, professionals, scientists, academicians, master's and doctoral students, and researchers in the disciplines of electrical and mechanical engineering.
Download or read book System Modeling Frameworks for Wind Turbines and Plants Review and Requirements Specifications written by and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: System modeling frameworks for wind turbines and plants are used by research groups and industry to design wind energy systems that take into account key trade-offs across performance, cost, and reliability at both the turbine and plant level. The frameworks are exercised using a variety of multi-disciplinary design, analysis and optimization (MDAO) methods. To improve inter-operability and foster collaboration, this report proposes a classification system for the frameworks along dimensions of model fidelity and scope. The classification system is first motivated with reviews the state-of-the-art in the development of software frameworks for integrated wind turbine and plant simulation. Within each major wind turbine and power plant subsystem, a matrix is developed for the disciplines used and the fidelity levels with which each discipline can be modeled. The existing frameworks are then classified according to the matrix. Next, an ontology is proposed that will allow for standardizing how data is transferred between the most common discipline-fidelity combinations used in the frameworks. A common representation of data creates the ability to 1) share system descriptions and analysis results, supporting more transparent benchmarks and comparison, and 2) integrate models together into workflows within and across organizations for improving the efficiency and performance of wind turbine and power plant design processes. Ultimately, this integration leads to better overall wind energy system designs with high performance and low costs.

Download or read book Modeling and Design of a DFIG Testbed for Protection Design Purposes written by Jiawei Dong and published by . This book was released on 2018 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, a Type III (Doubly Fed Induction Generator) wind generation system is analyzed and modeled. The results of this analysis are used to design and build a testbed for protection design and testing. The specic generator modeled is the four-pole, 10HP DFIG driven by a four-pole, 10HP induction machine powered by an adjustable speed drive. The testbed is made for research and development to analyze the DFIG during fault conditions. A future goal for the overall project is to design protection equipment for wind farms. The thesis presents the steady-state modelling and dynamic modelling of the DFIG, followed by a detailed switching model of the two-level voltage source converter (VSC). Two VSCs form a back-to-back converter which connects between the rotor windings and the power system. The grid side converter (GSC) interacts with the power system and the DC bus and is designed to maintain a constant DC bus voltage. The GSC is controlled to exchange power between the DC bus and the power system while tracking the system frequency. The power circuit, sensor circuit and control circuit for GSC are first designed and validated in simulation, then implemented in hardware. The protection logic is designed to protect the power electronics from overcurrent and overvoltage. The power control of the DFIG is achieved by rotor side converter (RSC) control strategies. The functionality of the RSC control is validated with simulation and could be implemented in hardware with similar hardware setups as the GSC.
