Download or read book Design Modeling and Analysis of a New Protection Scheme for Type 4 Wind Turbines written by Shashidhar Reddy Sathu and published by . 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 Final Report 02 ERD 056 Active Load Control Mitigation Using Microtabs written by and published by . This book was released on 2003 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: With public concern over the security and reliability of our existing electricity infrastructure and the resurgence of wind energy, the wind industry offers an immediate, first point of entry for the application and demonstration of an active load control technology. An innovative microtab approach is being investigated and demonstrated for active aerodynamic load control applications under the mid-year LDRD (June-Sept. 2002) effort. With many of these million dollar turbines failing at only half the design lifespans, conventional techniques for stiffening rotors, enlarging generators and gearboxes, and reinforcing towers are insufficient to accommodate the demands for bigger, taller and more powerful turbines. The DOE through the National Renewable Energy Laboratory (NREL) supports R & D efforts to develop lighter, more efficient and longer lasting wind turbines and advance turbine components. However, as wind turbine systems continue to increase in size and complexity, fundamental research and technology development has not kept pace with needs. New technologies to increase turbine life spans and to reduce costs are needed to realize wind electricity generation potentials. It is becoming quite evident that without a better understanding of static and dynamic response to normal and abnormal operating loads coupled with sophisticated flow analysis and control techniques, large turbine operating life and component life will be severely limited. Promising technologies include active load control and load alleviation systems to mitigate peak loads from damaging key components. This project addresses science and engineering challenges of developing enabling technologies for active load control for turbine applications using an innovative, translational microtab approach. Figure 1.1 illustrates the microtabs as applied on a wind turbine system. Extending wind turbine operating life is a crucial component for reducing the cost of wind-generated electricity, enabling wind energy market penetration and improving the reliability of the nation's renewable electrical generation infrastructure. This project also provides enabling technologies for improving turbine efficiency and durability to support the DOE and NNSA missions of providing energy security and reliability without contributing to greenhouse gas emissions and for decreasing dependence on foreign fuel sources. In addition to wind generator applications, the realization of a ''smart'' controllable structure for load control using the microtab approach has the potential to revolutionize design of other complex systems. Driven by cost and safety, both passive and active flow control for steady and unsteady conditions have been actively investigated by NASA, DARPA, DOE and other research institutions for application on rotorcraft, UAVs, marine vessels and wind turbine applications. The potential to obtain revolutionary advances in aerodynamic hydrodynamic performance, safety, maneuverability and service life by decreasing loads is an attractive prospect across many industries.

Book excerpt: Unlike conventional power plants, wind plants emit no air pollutants or greenhouse gases—and wind energy is a free, renewable resource. However, the induction machines commonly used as wind generators have stability problems similar to the transient stability of synchronous machines. To minimize power, frequency, and voltage fluctuations caused by network faults or random wind speed variations, control mechanisms are necessary. Wind Energy Systems: Solutions for Power Quality and Stabilization clearly explains how to solve stability and power quality issues of wind generator systems. Covering fundamental concepts of wind energy conversion systems, the book discusses several means to enhance the transient stability of wind generator systems. It also explains the methodologies for minimizing fluctuations of power, frequency, and voltage. Topics covered include: An overview of wind energy and wind energy conversion systems Fundamentals of electric machines and power electronics Types of wind generator systems Challenges in integrating wind power into electricity grids Solutions for power quality problems Methods for improving transient stability during network faults Methods for minimizing power fluctuations of variable-speed wind generator systems This accessible book helps researchers and engineers understand the relative effectiveness of each method and select a suitable tool for wind generator stabilization. It also offers students an introduction to wind energy conversion systems, providing insights into important grid integration and stability issues.

Download or read book An Algorithm for Default Detection of Wind Turbine Generators written by Jigneshkumar Pramodbhai Desai and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The protection of the wind turbine generator (WTG) required discrimination between internal and parallel WTG faults. Furthermore, it must discriminate the fault of its feeder line and parallel feeder line. This chapter describes the protection of wind turbine generators based on fault current and voltage analysis, which can identify the instantaneous operation, delay operation, or immune operation. A proposed Algorithm based digital relay is presented to provide all the different fault detection in a single unit suitable for internal and external fault protection of wind turbine generator. The main challenge to this scheme is that fault resistance may wrongly operate the scheme in some rare conditions. The phase angle of negative sequence current components determines the type of fault. The algorithm used negative sequence current and voltage to positive sequence current and voltage ratio, which is less than the set value in case of external fault. The fault seniors have been explained using simulation results on the wind turbine generator system modeled in a software environment.

Available in PDF, EPUB and Kindle. Book excerpt: Global energy demands have been increasing every year. There is a push towards switching to renewable sources of energy, primarily through wind energy, to meet these demands. The influence of wind turbine generators on power system dynamic performance is becoming increasingly important as global wind generation grows. In this thesis, the design and performance of a comprehensive protection scheme for a grid integrated Type 3 (Doubly Fed Induction Generator based) wind energy system is studied. The protection system is tested in real time by hardware-in-the-loop simulation using a Real Time Digital Simulator (RTDS). A multiple machine aggregated model is designed and tested for its response to various fault contingencies by connecting modern protective relays to the RTDS. The operating conditions of the wind energy system are varied to simulate a condition of geographically displaced wind turbine units, and the response of protection elements to numerous fault contingencies are recorded. The faults are analyzed from the relay's perspective and comparisons made, based on the challenges encountered during relay operation, to suggest improved protection settings and to ensure proper coordination between relays. The results showed that different fault contingencies, such as wind turbine operating states and faults with resistance, had an effect on the effectiveness of the protection scheme.
