“…Most of the simulation tools contain the governing equations of general systems and provide capability to correct or fit the characteristics of a specific system such that the final model is able to realistically show the detailed behavior. (Kim & Hwang, 2004;Lee & Kim, 2005; Lee, Yoon, Kim, & et al, 2007) Among the several commercial products for modeling gas turbine systems such as Gasturb or GT-MASTER THERMO-FLOW (Kurzke, 2001;Thermoflow Inc, 2004), we selected PEPSE-GT (Performance Evaluations of Power System Efficiencies -Gas Turbine) developed by ScienTech (Scientech, 2006), which we have a lot of experiences in developing turbine cycle models [Reference]. The code analysis is composed of two things: 1) basic modeling, 2) correction of field tests, and 3) sensitivity study.…”

“…Roth et al [5] reviewed the currently available methods of matching engine simulation models to available test data and suggested a new method. In addition, Li et al [6] suggested estimation of the component parameters at the design point based on an adaptation method, and Lee et al [7] estimated component parameters of a micro gas turbine adopting an inverse calculation method based on measured performance data.…”

In this work, component characteristics of a reheat cycle gas turbine in a commercial combined cycle power plant were evaluated. An inverse performance analysis, in which component characteristic parameters were estimated based on measured performance data, was carried out. The measured parameters were the power, the fuel flow rates of two combustors, and the temperatures and pressures at various locations such as the compressor discharge, exits of both the high-and low-pressure turbines. The estimated parameters from the analysis include the compressor and turbine efficiencies and the inlet air flow rate. The analysis was performed for a wide operation range in terms of the ambient temperature and load, providing a database for the variations of the characteristic parameters with changes in the operating condition. In addition, a sensitivity analysis was performed to examine the influence of the uncertainties of the measured parameters on the estimated parameters. The analysis program can be further developed into a performance diagnosis tool and the obtained component characteristic data can be used as reference database.

“…Due to the higher thermal efficiency, most of the current research on micro gas turbines is based on systems with recuperators. These include experimental analysis of micro gas turbine performance and component characteristics based on detailed measurements of various parameters [3]; an experimental and modeling study of the effect of three types of internal flow leakage on the performance of micro gas turbines [4]; experimental investigation of the effect of pressure loss between the compressor outlet and turbine inlet of a micro gas turbine-solid oxide fuel cell (SOFC/MGT) system on performance, including surging [5]; comprehensive thermodynamic modeling of a SOFC/MGT system for multi-effect desalination [6]; integration of a micro gas turbine system with thermally activated cooling technology and discussion of its performance parameters [7]; experimental and simulation studies of the performance parameters of a biogas-fuelled micro-gas turbine system, including surge [8], etc. The subjects of the above studies are characterized by integrated systems with recuperators and even with components such as fuel cells.…”

A thermal calculation based on a table of thermal properties of gas was carried out for a micro gas turbine system without a recuperator. The performance parameters of the micro gas turbine system were obtained. The results of the thermal calculations were verified using Aspen Plus, and it shows that the thermal calculations fit well with the Aspen simulation results. Based on this thermal calculation method, the variation of the performance parameters of the micro gas turbine system under different pressure and temperature ratios was analyzed. The results show that there is no optimum pressure ratio within the general design parameters of micro gas turbines, which leads to extreme values of thermal efficiency. The NOx generation in the combustion chamber of the micro gas turbine based on the Zeldovich mechanism was modeled and analyzed by coupling the one-dimensional thermal calculation model with the NOx emission model. The relationship between NOx generation rate, molar fuel factor, the characteristic pressure, and the characteristic temperature was obtained. The results of the analysis show that, in terms of controlling NOx emissions from a gas turbine, the use of an increased pressure ratio has a significant advantage over an increased temperature ratio to improve the thermal efficiency of the micro gas turbine.
