The advances in control and instrumentation have played one of the most important roles towards the improvements in power plant operation and performance. The range of applications has resulted in maximising thermal efficiency; optimising flow, level, pressure and temperature regulation; on-line monitoring and control of water and steam purity; and the prevention of excursions in plant metal temperatures which if not controlled would lead to reduced life of components. This volume comprehensively covers all aspects of control and instrumentation and its application. It deals in detail with the selection, evaluation, specification and standards for systems. An introduction to control theory is included together with the use of pneumatic, electrical and electronic equipment for systems throughout the power plant. Also covered are automation, protection, interlocks, analysis, control room design, system integrity, on-line computer control, and control and instrumentation supplies.
