Wind Turbine Generator Condition Monitoring via the Generator Control Loop

This thesis focuses on the development of condition monitoring techniques for application in wind turbines, particularly for offshore wind turbine driven doubly fed induction generators. The work describes the significant development of a physical condition monitoring Test Rig and its MATLAB Simulink model to represent modern variable speed wind turbine and the innovation and application of the rotor side control signals for the generator fault detection. Work has been carried out to develop a physical condition monitoring Test Rig from open loop control, with a wound rotor induction generator, into closed loop control with a doubly fed induction generator. This included designing and building the rotor side converter, installing the back-to-back converter and other new instrumentation. Moreover, the MATLAB Simulink model of the Test Rig has been developed to represent the closed loop control, with more detailed information on the Rig components and instrumentation and has been validated against the physical system in the time and frequency domains. A fault detection technique has been proposed by the author based on frequency analysis of the rotor-side control signals, namely; d-rotor current error, q-rotor current error and q-rotor current, for wind turbine generator fault detection. This technique has been investigated for rotor electrical asymmetry on the physical Test Rig and its MATLAB Simulink model at different fixed and variable speed conditions. The sensitivity of the each proposed signal has been studied under different operating conditions. Measured and simulated results are presented, a comparison with the results from using stator current and total power has been addressed and the improvement in condition monitoring detection performance has been demonstrated in comparison with previous methods, looking at current, power and vibration analysis

The role of public space in post-war reconstruction: the case of the redevelopment of Beirut city centre, Lebanon

This research emerges from the author's observations and from concerns shared by many local and international architects, urban designers and planners about policies and strategies adopted to reconstruct the city centre of Beirut following the Lebanese civil war (1975- 1990). Post -war reconstruction needs to be seen as a process that carefully restores and preserves the urban fabric as well as culture and heritage, and it should not be perceived as continuation of war by different means.A major postulate of this thesis is that post -war reconstruction is not just a physical phenomenon and needs to follow a holistic perspective that fulfils people's needs, perceptions and values. In other words, it is the unification of four attributes: the physical, socio- cultural, perceptual and functional attributes. Public space imbued with these attributes, in which they have interrelated relationships perceived through the transactional perspective to be a holistic phenomenon. Space can be used to guide the ongoing process of post -war reconstruction, as well as the natural evolution and transformation of the environment. The research assumes that shared identity, cultural continuity and collective memory can be achieved through the transaction of people in the space. To fulfil the thesis objectives, theories and principles on public space are reviewed and examined. A contextual review of the war and post -war period of the city centre of Beirut uncovers major concerns regarding its reconstruction policies and strategies.Public opinion and preferences are elicited using an open -ended questionnaire. Cognitive mapping is also used to examine the collective memory of people about the city centre and its spaces. A comparative spatial analysis is also employed to identify changes in accessibility and integration levels between the pre and post -war spaces.The consequence of the research outcome confirms that public space, through the transaction of people, provides the principles, qualities and meanings that respond to the authentic cultural forces and shared values of people, and the civic character of the city, which existed before the war and can still be seen shaping life today.The thesis, however, follows a logical progression of four interrelated parts. These are:PART ONE includes two chapters. Chapter One reviews a wide spectrum of literature on urban design principles. Chapter Two introduces attributes of public space.PART TWO comprises two chapters. Chapter Three focuses on reviewing the historical evolution of the old settlement of Beirut and its spaces, while Chapter Four outlines the implications caused by the civil war and its post -war reconstruction.PART THREE introduces the empirical work of the research in three chapters. Chapter Five reviews and analyses the questionnaire survey responses and results of 37 respondents. Chapter Six analyses the cognitive maps of the respondents using Lynch's five elements of The Image of the City. Chapter Seven presents the spatial analysis of the city centre of Beirut using space syntax (visibility graph analysis technique).PART FOUR is the concluding chapter. Chapter Eight examines the research findings and restates the thesis approach by proposing a framework for implementation and outlining its major characteristics

Naturalistic decision-making frameworks in multiprofessional assessment of early childhood disability

Young children with complex developmental difficulties are often referred for\ud assessment by multiprofessional groups run by health or education services.\ud The purpose of this research is to identify and describe the frameworks within\ud which such groups make their judgements and decisions in real work settings.\ud This study adopted an exploratory, multiple-case research design. It involved\ud two tertiary multiprofessional groups in London. Each assessed two preschool\ud children whose difficulties were suspected to lie within the autistic spectrum.\ud One group consisted of a paediatric senior registrar, a clinical psychologist and\ud a speech therapist working within a neurodisability centre attached to a\ud hospital (Site M); the other group was multi-agency, managed by an\ud Educational Psychology Service and included educational psychologists, a\ud psychotherapist and the deputy head of a special school (Site E). Each child\ud was assessed by all the professionals simultaneously in the presence of the\ud parents over a morning session. All discussions were audio-recorded. Postassessment\ud interviews were held with each participant. Data were subjected\ud to verbal protocol analysis and discourse and conversation analysis.\ud The major finding of the study was that professionals made use of four types\ud of interlinked decision-making frameworks, activated either concurrently or in\ud close alternation. Firstly, a common procedural framework included\ud hypothesis testing and diagnosis carried out in three cycles of decision\ud making, with varying characteristics related to the different institutional\ud contexts of each Site. Secondly, knowledge frameworks were mainly within\ud the 'disease' model at Site M, and the 'psychodynamic' and 'behavioural'\ud models at Site E. Thirdly, goal structures were related to which client and\ud purpose each assessment was intended to serve. Finally, negotiation\ud frameworks consisted of inter-professional collaboration and power-game\ud structures, and professional-parent interaction structures for negotiating the\ud bad news. These findings have implications for research on decision making\ud in assessment of children with disability, as well as for professional practice\ud and training

The European Social Forum and the Internet: a case of communications networks and collective action

Distinguished by its transnational scale, non-hierarchical organizing, and diverse composition, the 'movement for alternative globalization' is thought to partly derive this combination of characteristics from its use of the internet. My research is an attempt to explore this relationship by investigating the use of email lists for the preparation of the European Social Forum (ESF) in London in October 2004, one of the largest gatherings of the movement in Europe. Focusing on the processes of organizing, decision-making and collective identity formation, my study employed a combination of methods, including a preliminary survey, in-depth interviews, as. well as content analysis of the main ESF email lists. In terms of organizing, my thesis revealed that email lists are instrumental in constructing a flexible and polycentric organizing structure. They were also used extensively to widen up participation to the face-to-face organizing meetings, but also to legitimate the decision-making system and conceal its asymmetries of power. Furthermore, every list constituted a different 'site of identization' whose affordances for identity construction depended on its size, scale, and composition. In that respect, email lists constituted an infrastructure for the development of multiple identities within the movement. However, the lack of physical proximity and the limited capacity for conveying emotive content constrained the potential of email lists to foster relationships of trust and shared opinions which were instead facilitated by face-to-face communication. Overall, my thesis has identified a series of mechanisms and dynamics whose point of equilibrium determines the state of the movement at any point in time. In that respect, email and email lists tend to foster opening, divergence, multiplicity, and individuality, while face-to-face communication tends to generate closing, convergence, unity, and collectiveness. It is therefore the combination of these two forms of communication that helps the movement to have seemingly contrasting characteristics: to be united in difference or to be a collective that affirms individual subjectivity. However, my study has further shown that the capacity of the internet to foster such dynamics also depends on the specific cultures of organizing, political priorities, and ideological backgrounds of the people using it
