Project Title:
Performance test and tuning of 5 to 8 gas turbine units of
Kerman combined cycle power plant
Department: Measurement & Control Department
Employer: Kerman power production company
Project Staff: S. Shahmansouri, N. Irani, H.R. Khalesi,
Project Manager: Edward Gharibian
Project Code: CECTBK01
Project Summary:
Performance of gas turbine units are affected by ambient conditions namely ambient
temperature, pressure and humidity. Hence gas turbine control systems are designed so
that they maintain the optimal performance of gas turbine in variety of conditions.
Optimal performance means setting turbine to work safely at its maximum permissible
power. Due to sensitivity of gas turbine to ambient condition after major overhauls,
tuning of control system settings is necessary for optimal operation of gas turbine.
These settings are done by performance testing of unit and calculation of combustion
products entering first stage of turbine. Precise calculation is vital because if the
temperature is set to lower value the unit cannot produce at its maximum power and will
result in loss of production and if temperature is set to higher value the life of first stage
blades will reduce and event may damage these blades. In this project the settings of
V94.2 gas turbine of Kerman power plant were tested and tuned for optimal
performance of unit.
