Electrical and Mechanical Fault Diagnosis in Wind Energy Conversion Systems
Wind energy conversion systems are subject to many different types of faults and therefore fault detection is highly important to ensure reliability and safety. Monitoring systems can help to detect faults before they result in downtime. This book presents efficient methods used to detect electrical and mechanical faults based on electrical signals occurring in the different components of a wind energy conversion system. For example, in a small and high power synchronous generator and multi-phase generator, in the diode bridge rectifier, the gearbox and the sensors. This book also presents a method for keeping the frequency and voltage of the power grid within an allowable range while ensuring the continuity of power supply in the event of a grid fault. Electrical and Mechanical Fault Diagnosis in Wind Energy Conversion Systems presents original results obtained from a variety of research. It will not only be useful as a guideline for the conception of more robust wind turbines systems, but also for engineers monitoring wind turbines and researchers
Electrical Machines Diagnosis
Monitoring and diagnosis of electrical machine faults is a scientific and economic issue which is motivated by objectives for reliability and serviceability in electrical drives. This book provides a survey of the techniques used to detect the faults occurring in electrical drives: electrical, thermal and mechanical faults of the electrical machine, faults of the static converter and faults of the energy storage unit. Diagnosis of faults occurring in electrical drives is an essential part of a global monitoring system used to improve reliability and serviceability. This diagnosis is performed with a large variety of techniques: parameter estimation, state observation, Kalman filtering, spect...

This book deals with the emerging generation of renewable energy technologies, covering solar energy (photovoltaic, thermal and thermodynamic energy conversion), wind energy, marine energy, small hydropower, geothermal energy, biofuels, biogas and the use of wood as a substitute for fossil fuels.
Renewable Energy for Sustainable Growth Assessment
RENEWABLE ENERGY FOR SUSTAINABLE GROWTH ASSESSMENT Written and edited by a team of experts in the field, this collection of papers reflects the most up-to-date and comprehensive current state of renewable energy for sustainable growth assessment and provides practical solutions for engineers and scientists. Renewable energy resources (RERs) are gaining more attention in academia and industry as one of the preferred choices of sustainable energy conversion. Due to global energy demand, environmental impacts, economic needs and social issues, RERs are encouraged and even funded by many governments around the world. Today, researchers are facing numerous challenges as this field emerges and dev...
Women's Rights in the Middle East and North Africa
Freedom HouseOs innovative publication WomenOs Rights in the Middle East and North Africa: Progress Amid Resistance analyzes the status of women in the region, with a special focus on the gains and setbacks for womenOs rights since the first edition was released in 2005. The study presents a comparative evaluation of conditions for women in 17 countries and one territory: Algeria, Bahrain, Egypt, Iran, Iraq, Jordan, Kuwait, Lebanon, Libya, Morocco, Oman, Palestine (Palestinian Authority and Israeli-Occupied Territories), Qatar, Saudi Arabia, Syria, Tunisia, United Arab Emirates, and Yemen. The publication identifies the causes and consequences of gender inequality in the Middle East, and pro...
PATRIMONIAL POWER in the MODERN WORLD
During the 2011 uprisings in the Arab world, protesters demanded the ouster of authoritarian forms of rule and an end to the influence of ruling families on politics, society, and the economy. These upheavals revealed that patrimonial power in its diverse forms is still a dynamic force in global politics, able to shape world events. This volume brings the study of patrimonialism back to center stage and presents the concept as a useful tool to analyze how nations, global developments, and international relations are influenced and transformed. Leading scholars show that patrimonial practices, present throughout history, are important features of global capitalist modernity. The authors analyze patrimonial politics in regions throughout the world, including in the United States, Tunisia, Chile, France, Iraq, Lebanon, Morocco, Poland, and Russia. This volume will appeal to students of politics and policy and to a multidisciplinary scholarly audience in political sociology, historical social science, history, and social theory.
