Today gas turbine performance is of paramount importance as it directly influences the profitability of any business that employ them. It is indeed the end product that operators purchase and manufacturers have to guarantee. Gas turbine performance is affected by various factors. These include ambient conditions, performance deterioration and control system performance. Therefore, this course on industrial gas turbine performance engineering addresses these issues and has been design using simulators. The use of simulators in training and education brings a holistic understanding of the subject and therefore increases the width and depth of understanding. This differs from traditional methods such as numerical exercises, which gives a somewhat narrow understanding and can also be laborious. However, the course begins with the discussion of theory of gas turbine performance and operation, and then uses these virtual engines to revisit the theory by applying these simulators.

We have therefore divided the course into three parts. In Part 1, we discuss the thermodynamics of gas turbine cycle and the performance of engine components such as compressors, turbines and combustion. This includes the performance behaviour of gas turbines during off-design operating conditions as this is where the gas turbine operates for most of its life. The impact of performance deterioration on engine performance, turbine creep life usage and emissions are also included. The performance engine control systems are also discussed as applied to a single and two-shaft gas turbine operating with a free power turbine.

In Parts 2 and 3 we revisit Part 1, where we employ gas turbine simulators to illustrate much of the discussion in Part 1, particularly the effects of ambient conditions, performance deterioration and control system performance on engine performance, turbine creep life usage and emissions. We have also included power augmentation techniques in the latter parts of the course and include peak rating, maximum continues rating and turbine inlet cooling, which is becoming increasingly popular. The simulation of control system performance is also discussed and includes the simulation of faults associated with control systems. Two simulators are employed and they correspond to the single shaft gas turbine, which is extensively used in power generation, and the two-shaft gas turbine operating with a free power turbine, which is widely used in mechanical drive and naval applications. Thus, these two cover the vast majority of gas turbine configurations operating in the field.

Completion of this course requires the use of single shaft and two-shaft gas turbine simulators, available from Gas Path Analysis Limited. The simulators can be downloaded and used free of charge for 14 days. Download the trial now.
