Combined Cycle Power Generation Plants

This 3-day course deals with the design and detailed operation and maintenance characteristics of a Gas turbine combined cycle power plant, with major emphasis on the major plant Components and the performance of the plant. Overall design and operation concepts along with basic operation and maintenance problems for the various pieces of Turbo-Machinery including Gas Turbines, Steam Turbines, Generators, HRSG and Balance of plant Rotating equipment will be discussed.

Discussions and design parameters of the Heat Recovery and Steam Generating (HRSG) systems, the feed water heaters and the Condensers are also included. Other topics covered include plant systems viz, fuel, electrical, pneumatic, hydraulic, instrumentation, components and BOP reliability program, Thermal performance analysis, vibration analysis and on-line condition monitoring of the Power Plant. An emphasis is placed on providing practical information with minimal theory.

Case studies with an aim of thorough understanding of Combined Cycle Power Plant life extension and evaluation and Performance Benchmarking for a typical 1400MW will be discussed in detail. Participants are encouraged throughout the course to be engaged in active discussions so as to maximize sharing of knowledge.
