Manuela Gomes Controlling and Monitoring Air Speed in a Wind Tunnel


Bachelor Thesis from the year 2015 in the subject Engineering - Computer Engineering, , course: Bachelor of Engineering (Honours) in Mechatronics, language: English, abstract: The project proposes a construction of a wind tunnel controlled and monitored by a system containing a Web Based monitoring interfaced to a Programmable Logic Control network that carries out an application program which receives inputs from an anemometer sensor for measuring the airspeed performed by the fan and from a User Computer, which chooses airspeed values to be implemented by the Brushless fan. Both inputs are compared by the PID controller, control mode used by the PLC system, and the output is generated with base on the inputs received by the PID controller.This system after set properly, is able to measure airspeed value provided by the Brushless fan in real time, transferring it to the PLC via internet where it is displayed in a Web page developed for this system.

Raihan Md. Abu, Habib Md. Habibur Rahman, Munjer Md. Abul Variable Voltage Control of Wind Turbine Gen


This book represents different types of renewable energy, the behavior of renewable energy.The world is hunger of energy. The conventional energy is decreasing day by day. The use and necessity of renewable energy is discussed with respect to all over the world. A wind farm consists of several wind turbines.It is essential to connect the wind farm. Wind energy and wind firm are also discussed then it covers essential topics about wind turbine systems such as wind turbine generation system, wind power output, mechanical power extracted from wind.The speed of wind is not constant as well as the generated voltage is not also constant.Finally a wind farm integrated power system is designed and in simulation it is tried to keep the voltage constant by controlling the pitch angle of the wind turbine.

Bin Wu Model Predictive Control of Wind Energy Conversion Systems


Model Predictive Control of Wind Energy Conversion Systems addresses the predicative control strategy that has emerged as a promising digital control tool within the field of power electronics, variable-speed motor drives, and energy conversion systems. The authors provide a comprehensive analysis on the model predictive control of power converters employed in a wide variety of variable-speed wind energy conversion systems (WECS). The contents of this book includes an overview of wind energy system configurations, power converters for variable-speed WECS, digital control techniques, MPC, modeling of power converters and wind generators for MPC design. Other topics include the mapping of continuous-time models to discrete-time models by various exact, approximate, and quasi-exact discretization methods, modeling and control of wind turbine grid-side two-level and multilevel voltage source converters. The authors also focus on the MPC of several power converter configurations for full variable-speed permanent magnet synchronous generator based WECS, squirrel-cage induction generator based WECS, and semi-variable-speed doubly fed induction generator based WECS. Furthermore, this book: Analyzes a wide variety of practical WECS, illustrating important concepts with case studies, simulations, and experimental results Provides a step-by-step design procedure for the development of predictive control schemes for various WECS configurations Describes continuous- and discrete-time modeling of wind generators and power converters, weighting factor selection, discretization methods, and extrapolation techniques Presents useful material for other power electronic applications such as variable-speed motor drives, power quality conditioners, electric vehicles, photovoltaic energy systems, distributed generation, and high-voltage direct current transmission. Explores S-Function Builder programming in MATLAB environment to implement various MPC strategies through the companion website Reflecting the latest technologies in the field, Model Predictive Control of Wind Energy Conversion Systems is a valuable reference for academic researchers, practicing engineers, and other professionals. It can also be used as a textbook for graduate-level and advanced undergraduate courses.

Michael Brower Wind Resource Assessment. A Practical Guide to Developing a Wind Project


A practical, authoritative guide to the assessment of wind resources for utility-scale wind projects—authored by a team of experts from a leading renewable energy consultancy The successful development of wind energy projects depends on an accurate assessment of where, how often, and how strongly the wind blows. A mistake in this stage of evaluation can cause severe financial losses and missed opportunities for developers, lenders, and investors. Wind Resource Assessment: A Practical Guide to Developing a Wind Project shows readers how to achieve a high standard of resource assessment, reduce the uncertainty associated with long-term energy performance, and maximize the value of their project assets. Beginning with the siting, installation, and operation of a high-quality wind monitoring program, this book continues with methods of data quality control and validation, extrapolating measurements from anemometer height to turbine height, adjusting short-term observations for historical climate conditions, and wind flow modeling to account for terrain and surface conditions. In addition, Wind Resource Assessment addresses special topics such as: Worker safety Data security Remote sensing technology (sodar and lidar) Offshore resource assessment Impacts of climate change Uncertainty estimation Plant design and energy production estimatio Filled with important information ranging from basic fundamentals of wind to cutting-edge research topics, and accompanied by helpful references and discussion questions, this comprehensive text—designed for an international audience—is a vital reference that promotes consistent standards for wind assessment across the industry.
