ABSTRACT:
The tests of assessment in gas turbines can determine the termal conduct of the thermodynamic cycles. With the operating it the package 4 of the CTVM. Wich is formed by one unid of vapor of 300 MW and has been repowered with three units of gas of 83 MW. In his general whole until 550MW to a maximiun capacity.
In this work is used the design of the tecnology of gas turbine GT1N2 ALSTOM.
Starting of the real data of operation to one regulated charge, it makes a thermodynamic analysis applying the methodology of real cycle turbine of gas. And it´s makes a comparison with the data of design by means the use of the tool GTPRO of termoflow 23.0. It´s calculated the thermal efficiency of the steam turbine of the high, médium and small pressure; Isentropic efficiency of the gas turbines and compressors. So like the thermal efficiency of conventional cycle, combined cycle, hybrid cycle and open cycle. Parameters that allow decide the current state of the unids for a new disposition of repowering

Keywords: Repowering, gas turbine, steam turbine, thermoelectric plant, efficiency
