The candidates will be able to explain the effect of operating parameters such as firing temperatures, compressor pressure ratios, ambient temperature and pressure conditions, turbine exhaust temperatures and their effect on gas turbine efficiency/power output, and the combined cycle efficiency/power output. This course goes through the overview of a combined cycle gas turbine; this will be followed by the different types of Gas Turbine. This is then expanded on to give a detailed understanding of the performance and management of the operations of a combined cycle gas turbine.

By the end of this course delegates will be able to:

• Obtain an understanding of the performance of a Combined Cycle Gas Turbine
• Identify the different types of Combined Cycle Gas Turbine, Gas Turbine Performance and Power Plant Operation

Electrical Engineers, Power Generation Engineers, Power System Protection Engineers, Gas turbine newcomers and more experienced persons who desire an overview of the many available gas turbine technologies, Process Control Engineers & Personnel, Electrical and Instrumentation Technicians & Design Engineers, Maintenance Technicians & Supervisors, Plant Operators & Technicians, Oil & Gas Industry Personnel
