    The emerging environmental and energy system related requirements urge renewed combustion systems, with a focus on extended flexibility and decreased emissions. At the same time, monitoring and measurement reliability requirements are increasing. All these requirements also increasingly affect existing combustion plants.To tackle the increasing needs and requirements of existing combustion processes, this thesis’ objective is to integrate process and domain knowledge, models, and online estimation to provide cost effective and practically feasible solutions for online emission monitoring and control in existing combustion processes. These solutions are domain specific, comprising power level, main fuel, boiler technology, process environment, and market. This thesis presents a framework to provide practically justified, online monitoring and control solutions that is applied to selected combustion applications.The first application is combustion control of small-scale (100 MW). A novel, first principle combustion model was developed for these. The generic combustion model interlinks the combustion related measurements distributed within any boilers regardless of boiler type or fuels. The interlinking enables combustion processes to be considered as an entity that reveals if a measurement provide realistic readings compared with others. The static, computationally light model enables simultaneous data reconciliation and gross error detection and hence several attractive online applications, such as reliable estimation of unmeasured variables, and separation of process disturbances from sensor malfunctions.The results verify that the process performance improved in all studied practical applications, providing feasible solutions for increasing requirements

    Microgrids are a growing segment of the energy industry, representing a paradigm shift from centralized structures toward more localized, autonomous, dynamic, and bi-directional energy networks, especially in cities and communities. The ability to isolate from the larger grid makes microgrids resilient, while their capability of forming scalable energy clusters permits the delivery of services that make the grid more sustainable and competitive. Through an optimal design and management process, microgrids could also provide efficient, low-cost, clean energy and help to improve the operation and stability of regional energy systems. This book covers these promising and dynamic areas of research and development and gathers contributions on different aspects of microgrids in an aim to impart higher degrees of sustainability and resilience to energy systems

    Study of fuzzy logic in safety and control systems in nuclear power plants

    Safety and control systems in Nuclear Power Plants are essentially run without intelligent systems. As nuclear industry starts to become more advanced and vendors are starting to manufacture more advance products, old structures and systems in place will eventually become obsolete needing alternatives to resolve discrepancies. Control System is considered as one protective layer with plant safety systems. Research demonstrates that intelligent control systems improve safety performance of power plants. This research studies fuzzy logic control (i.e. intelligent control system), its methodology, design and applicability to safety related systems in Nuclear Power Plant. Study further investigates fuzzy logic control approach and how it impacts improving safety related system performance. Critical system parameters and trends were studied, research plan developed and results recorded using Matlab & Simulink applications. Two case studies selected demonstrate proposed fuzzy logic with effective results. First study demonstrates how implementing fuzzy logic improves operability of self-contained pneumatic assemblies that impact improving breathing air system performance. Second study demonstrates how fuzzy logic implementation can improve instrument air compressor performance with early detection of solenoid valve failures. Both studies reveal that using fuzzy logic results in better control, precision and performance in maintaining safety related systems and encourages its use to many other applications
