New topics in this updated edition include plant safety lifecycles and safety integrity levels, advanced ultra-supercritical plants with advanced firing systems and associated auxiliaries, integrated gasification combined cycle (IGCC) and integrated gasification fuel cells (IGFC), advanced control systems, and safety lifecycle and safety integrated systems. Covers systems in use in a wide range of power plants: conventional thermal power plants, combined/cogen plants, supercritical plants, and once through boilers Presents practical design aspects and current trends in instrumentation Discusses why and how to change control strategies when systems are updated/changed Provides instrumentation selection techniques based on operating parameters. Spec sheets are included for each type of instrument Consistent with current professional practice in North America, Europe, and India All-new coverage of Plant safety lifecycles and Safety Integrity Levels Discusses control and instrumentation systems deployed for the next generation of A-USC and IGCC plants

Power-plant Control and Instrumentation, 2nd edition - contents include a wide variety of plant and combustion arrangements, from smaller boiler systems to full-scale generators, common principles, commercial aspects, measurement, and key techniques such as cogeneration and combined cycle.

The second edition of this text presents an overview of power generation and discusses the different types of equipment used in a steam thermal power generation unit. The book describes various conventional and non-conventional energy sources. It elaborates on the instrumentation and control of water-steam and fuel-air flue gas circuits along with optimization of combustion. The text also deals with the power plant management system including the combustion process, boiler efficiency calculation, and maintenance and safety aspects. In addition, the book explains Supervisory Control and Data Acquisition (SCADA) system as well as turbine monitoring and control. This book is designed for the undergraduate students of electronics and instrumentation engineering and electrical and electronics engineering. New To This Edition • A new chapter on Nuclear Power Plant Instrumentation is added, which elaborates how electricity is generated in a Nuclear Power Plant. Key Features • Includes numerous figures to clarify the concepts. • Gives a number of worked-out problems to help students enhance their learning skills. • Provides chapter-end exercises to enable students to test their understanding of the subject.

A practical guide to increasing power plant operating uptime and profitability Power Plant Instrumentation and Controls provides a detailed description of power plant computer simulation and modern instrumentation and control systems that allow improvements in online power plant operating periods and thus profitability – minimizing unnecessary outages, maintenance activities, and downtime. The book reviews the many benefits of these different computer simulation programs, modern instrumentation, and control systems as they relate to plant safety, reliability, costs, efficiency, and emissions. It focuses on modern power generating plants – gas turbines, co-generation, and combined cycle plants. The book features a simulation program to determine the effects on turbine performance; turbine creep life; environmental emissions; and turbine life-cycle cost, revenue, and profitability of the following parameters: Variations in ambient temperature and pressure Inlet and exhaust losses Engine deterioration Different faults Power augmentation methods, including peak mode Water injection Control system performance, including proportional offset, integral windup, and trips Fuel type Variations in maintenance techniques and frequency Power generating plant outages are often due to unnecessary and improper maintenance activities and poor or outdated instrumentation and control systems, resulting in a significant reduction in profitability of power plant operation. This authoritative volume addresses these concerns and offers proven solutions. It is an essential next step to Kiameh's successful Power Generation Handbook and Power Plant Equipment Operation and Maintenance Guide. Power Plant Instrumentation and Controls includes Bar charts trending key turbine parameters Bar charts trending compressor characteristics and operating point during engine transients Tips for exporting simulated data to other software, such as Excel Exercises to illustrate use of simulation programs under different scenarios, including modern co-generation and combined-cycle plants In-depth coverage of smart instrumentation and advanced control systems used in modern power generating plants Details on selecting, commissioning, operating, diagnosing, and testing smart instrumentation, Distributed Control Systems, Supervisory Control and Data Acquisition (SCADA) systems, and all types of control valves, actuators, and positioners

An exploration of how advances in computing technology and research can be combined to extend the capabilities and economics of modern power plants. The contributors, from academia as well as practising engineers, illustrate how the various methodologies can be applied to power plant operation.

To achieve the highest level of availability and cost-effectiveness the steam turbine generator set in power plants must be operated professionally at optimum thermodynamic performance. The modern I&C equipment (Instrumentation & Control) of Siemens Power Generation (KWU) and the on-line diagnostic system DIGEST help accomplish this by providing a comprehensive overview of the operating status and by analyzing the condition of the steam turbine generator set during operation. This equipment enables the early detection of incipient faults and lowers the burden of the operating crew. This book provides a broad overview of the state-of-the-art of I&C equipment and the use of diagnostic systems. The target group for this book are power plant operators, planning engineers and consultants.
