About the course

This COURSE will cover all aspect of combined cycle power plants. All the equipment of combined cycle power plants such as: compressors, gas and steam turbines, combustors, heat recovery steam generators, deaerators, condensers, lubricating systems, instrumentation, control systems, transformers, and generators will be covered in detail. The design, selection considerations, operation, maintenance, pay-back period, economics of combined cycles, as well as, emission limits, reliability, monitoring and governing systems will also be covered thoroughly. This seminar will also provide up-dated information in respect to all the significant improvements that have been made to combined cycle power generating plants during the last two decades.

This seminar will illustrate through sophisticated computer simulation how gas turbines, and combined cycle plants perform under steady-state and transient conditions. In addition, the delegates will learn how to use the computer simulation program which provides the following benefits:

  • Allow the operator to extend the combined cycle power plant operating period by avoiding unnecessary outages and maintenance activities.
  • Determination of essential combined cycle power plant maintenance activities to reduce the duration of outages.
  • Profit optimization of combined cycle power plants.
