This book addresses the key concerns regarding the operation of wind turbines in cold climates and focuses in particular on the analysis of icing and methods for its mitigation. Topics covered include the implications of cold climates for wind turbine design and operation, the relevance of icing for wind turbines, the icing process itself, ice prevention systems and thermal anti-icing system design. In each chapter, care is taken to build systematically on the basic knowledge, providing the reader with the level of detail required for a thorough understanding. An important feature is the inclusion of several original analytical and numerical models for ready computation of icing impacts and design assessment. The breadth of the coverage and the in-depth scientific analysis, with calculations and worked examples relating to both fluid dynamics and thermodynamics, ensure that the book will serve not only as a textbook but also as a practical manual for general design tasks.

The total worldwide base of installed wind energy peak capacity reached 197 GW by the end of 2010. Wind turbine systems are being installed often in mountains and cold weather regions, due to their high wind energy potential. Harsh cold weather climates affect wind turbine performance. Ice accretion and irregular shedding during turbine operation lead to load imbalances, vibration and structural failures, often causing the turbine to shut off. This book presents an experimental investigation including three important fundamental aspects: energy losses of wind energy while a wind turbine is operating under icing conditions; aerodynamic characteristics of an airfoil during a simulated icing event and heat transfer characteristics of the airfoil with and without liquid water content at varying angles of attack. The drag, lift and moment are measured by a force balance system to obtain the aerodynamics of an iced airfoil. The book also quantifies the power loss under various icing conditions. The data obtained can be used to validate numerical models and predict heat transfer characteristics when wind turbines operate in cold climate regions.

Providing electric power to remote, cold regions at high latitude or altitude can be an expensive and technically challenging task. Photovoltaics (PV) provide a reliable and cost-effective solution yet their potential is underdeveloped, in part because of a lack of knowledge about their effectiveness in cold climates. This book illustrates the potential and the techniques for using PV in cold climates. The book starts with a general section illustrating how PV can be applied in cold climates, with a succinct overview of the main considerations and chapters covering both the solar resource and the economics. It then covers the effects of cold climates on PV systems looking at the issues around the array and electronics, the battery and energy management. The third section covers design considerations and possible configurations (stand alone/battery systems, hybrid systems, seasonal storage and system simulation). The next part covers installation and operation and the book concludes with several case studies. The book will be invaluable both for all managers charged with providing power to cold climates whether for dwellings, other buildings or technical installations and for all technicians, engineers, installers and researchers working on such installations. It will also be of great interest to those working with PV in any form, or interested to see PV technology reach its full potential.

Wind Turbine Icing Physics and Anti-/De-Icing Technology gives a comprehensive update of research on the underlying physics pertinent to wind turbine icing and the development of various effective and robust anti-/de-icing technology for wind turbine icing mitigation. The book introduces the most recent research results derived from both laboratory studies and field experiments. Specifically, the research results based on field measurement campaigns to quantify the characteristics of the ice structures accreted over the blades surfaces of utility-scale wind turbines by using a Supervisory Control and Data Acquisition (SCADA) system and an Unmanned-Aerial-Vehicle (UAV) equipped with a high-resolution digital camera are also introduced. In addition, comprehensive lab experimental studies are explored, along with a suite of advanced flow diagnostic techniques, a detailed overview of the improvements, and the advantages and disadvantages of state-of-the-art ice mitigation strategies. This new addition to the Wind Energy Engineering series will be useful to all researchers and industry professionals who address icing issues through testing, research and industrial innovation. Covers detailed improvements and the advantages/disadvantages of state-of-the-art ice mitigation strategies Includes condition monitoring contents for lab-scale experiments and field tests Presents the potential of various bio-inspired icephobic coatings of wind turbine blades

Large-scale wind power generation is one of the fastest developing sources of renewable energy and already makes a substantial contribution to power grids in many countries worldwide. With technology maturing, the challenge is now to increase penetration, and optimise the design, construction and performance of wind energy systems. Fundamental issues of safety and reliability are paramount in this drive to increase capacity and efficiency. Wind energy systems: Optimising design and construction for safe and reliable operation provides a comprehensive review of the latest developments in the design, construction and operation of large-scale wind energy systems, including in offshore and other problematic environments. Part one provides detailed coverage of wind resource assessment and siting methods relevant to wind turbine and wind farm planning, as well as aeroelastics, aerodynamics, and fatigue loading that affect the safety and reliability of wind energy systems. This coverage is extended in part two, where the design and development of individual components is considered in depth, from wind turbine rotors to drive train and control systems, and on to tower design and construction. Part three explores operation and maintenance issues, such as reliability and maintainability strategies and condition monitoring systems, before discussing performance assessment and optimisation routes for wind energy systems in low wind speed environments and cold climates. Part four reviews offshore wind energy systems development, from the impact of environmental loads such as wind, waves and ice, to site specific construction and integrated wind farm planning, and of course the critical issues and strategies for offshore operation and maintenance. With its distinguished editors and international teams of contributors, Wind energy systems is a standard reference for wind power engineers, technicians and manufacturers, as well as researchers and academics involved in this expanding field. Reviews the latest developments in the design, construction and operation of large-scale wind energy systems Offers detailed coverage of wind resource assessment and siting methods relevant to wind turbine and wind farm planning Explores operation and maintenance issues, such as reliability and maintainability strategies and condition monitoring systems
