Power Plant Instrumentation And Controls

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frequency Power generating plant outages are often due to unnecessary and improper maintenance activities and poor or outdated instrumentation and control systems, resulting in a significant reduction in profitability of power plant operation.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

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.

Accidents and natural disasters involving nuclear power plants such as Chernobyl, Three Mile Island, and the recent meltdown at Fukushima are rare, but their effects are devastating enough to warrant increased vigilance in addressing safety concerns. Nuclear Power Plant Instrumentation and Control Systems for Safety and Security evaluates the risks inherent to nuclear power and methods of preventing accidents through computer control systems and other such emerging technologies. Students and scholars as well as operators and designers will find useful insight into the latest security technologies with the potential to make the future of nuclear energy clean, safe, and reliable.

The nuclear industry and the U.S. Nuclear Regulatory Commission (USNRC) have been working for several years on the development of an adequate process to guide the replacement of aging analog monitoring and control instrumentation in nuclear power plants with modern digital instrumentation without introducing off-setting safety problems. This book identifies criteria for the USNRC's review and acceptance of digital applications in nuclear power plants. It focuses on eight areas: software quality assurance, common-mode software failure potential, systems aspects of digital instrumentation and control technology, human factors and human-machine interfaces, safety and reliability assessment methods, dedication of commercial off-the-shelf hardware and software, the case-by-case licensing process, and the adequacy of technical infrastructure.

Describes control systems for boilers and heat-recovery steam generators (HRSGs) in a variety of applications, from waste-to-energy plants to combined-cycle gas-turbine power stations. Basics such as methods of connecting instruments are explained, and more advanced discussions of design features of distributed control systems are also included. At every stage, emphasis is given to the interactive nature of plants and to troubleshooting and problem solving. Includes chapter summaries. The author is Fellow of the Institution of Electrical Engineers, and the Institute of Marine Engineers, and is a Senior Member of the Instrument Society of America.
