Evaluación Exergoeconómica utilizando herramientas complementarias para mejorar el Rendimiento Operativo de una Central de Ciclo Combinado en un Sistema Interconectado

Abstract

Se realizó la evaluación exergética y exergoeconómica de una central de ciclo combinado utilizando tres herramientas de cálculo informático, para así afinar el diagnóstico conducente a mejorar su rendimiento operativo. La finalidad es evaluar con una mayor aproximación las irreversibilidades asociadas a los costos exergoeconómicos. La metodología inicia con una auditoría energética en línea, seguidamente la evaluación exergética y exergoeconómica en cada proceso calculado de forma estructurada en Ms Excel, luego en EES (Engineering Equation Solver) y finalmente con GT PRO de Thermoflow. Entre los resultados se observa excesos de irreversibilidades en la cámara de combustión y caldera recuperadora HRSG, así como mayores costos exergoeconómicos de enfriamiento en el aerocondensador; el cálculo complementario entre MS Excel, GT PRO y EES permitió disminuir los márgenes de error de las variables termoenergéticas, logrando así una evaluación comparativa de mejor aproximación y disposición para su integración al sistema de control de la central.

The exergetic and exergoeconomic evaluation of a combined cycle power plant was carried out using three computer calculation tools, in order to fine-tune the diagnosis leading to improving its operating performance. The purpose is to evaluate with a greater approximation the irreversibilities associated with the exergoeconomic costs. The methodology begins with an online energy audit, followed by the exergetic and exergoeconomic evaluation in each process calculated in a structured way in Ms Excel, then in EES (Engineering Equation Solver) and finally with Thermoflow's GT PRO. Among the results, excesses of irreversibilities are observed in the combustion chamber and HRSG, as well as higher exergoeconomic costs of cooling in the aerocondenser; the complementary calculation between MS Excel, GT PRO and EES allowed to reduce the margins of error of the thermo-energy variables, thus achieving a comparative evaluation of better approximation and disposition for its integration into the plant control system.
