The growth of power markets stresses the importance of optimizing power plant performance and boosts the need to improve and upgrade the existing power generation plants. In this framework, Gas Turbine with medium power output are regarded as strategic asset to gain competitiveness in energy business. In such a challenging scenario, the current version of the 50/60 cycles AE64.3A Gas Turbine has been upgraded by Ansaldo Energia, enhancing performances, operational and dynamic features. Therefore the unit is rated now 75 Mwe power output and 35.9% efficiency. The upgraded AE64.3A along with the relevant generator and auxiliary systems in single shaft configuration, has been installed in the combined cycle generation plant of Vlore, on the Adriatic coast of Albania. The gas turbine has been supplied in accordance to the standard and proven design of the manufacturer, optimizing the need for burning fuel oil in continuous operation. The paper will report the main feature of the engine highlighting the upgrade and present the operational experience gained during the commissioning phase.Copyright © 2011 by ASME |
