This paper describes the upgrade of a GE Frame 3 industrial gas turbine with new advanced technology parts and a new microprocessor-based control system. Based on pre- and post-upgrade performance tests, the gas turbine heat rate was reduced by 9.4%. In addition, with the new triple redundant control system and upgraded hardware, unit availability is anticipated to improve by 18% over the extended life of the gas turbine. The paper describes the mechanical and control changes and the method used to measure the enhancement of unit performance.
