“…This result is valid in the particular analyzed case of a single-shaft gas turbine working in parallel with electrical mains. Different results would be obtained, for example, in the cases of two-shaft gas turbines with rotational speed controller (Blotenberg, 1993) or of gas turbine aircraft engines (DeHoff and Hall, 1978;Szuch, 1978). In these cases, the dynamic phenomena due to the working gas mass contained in the gas turbine component volumes affect the rotational speed transient response.…”

“…A large number of different dynamic gas turbine models have widespread utilization in research and in the technical world (DeHoff and Hall, 1978;Szuch, 1978;Schobeiri, 1987 ;Krikelis and Papadalcis, 1988;Blotenber g, 1993;Bettocchi et al, 1996). These models differ from one another on the basis of lower or greater accuracy, as well as on the dynamic phenomena considered as follows:…”

In this paper, the transient responses of different dynamic models of a generator drive single shaft gas turbine working in parallel with electrical mains, have been analyzed. The time variations of the main thermodynamic and performance parameters are obtained by varying the fuel valve position, for an assigned IGV angle, and by varying the IGV angle for an assigned fuel valve position. The influence of the dynamic phenomena due to the working gas mass contained in the gas turbine component volumes, of the metal mass thermal inertia and of the heat transfers, are taken separately into account. The dynamic balance of rotating masses is not instead considered, since the single shaft gas turbine works in parallel with electrical mains. The developed analysis has shown the negligible influence of the phenomena due to the working gas mass contained in the gas turbine component volumes and a more significative effect of the metal mass inertia and of the heat transfers on the transient response. In particular, this influence is significative only for gas turbine and compressor outlet temperatures. The influence on the gas turbine transient behaviour of the control system that uses the gas turbine outlet temperature in feedback has been also evaluated.

Numerous problems are encountered in realizing an adequate real time model for an aircraft engine. The purpose of this article is to propose a systematic approach for modeling and approximating the characteristics of an engine or engine component parts, and to apply this approach to the Viper compressor (VC) characteristics. The proposed approach introduces a set of quantitative model-performance measures. Monitoring these measures makes it possible to take care of the multiple objectives of the model simultaneously and individually, and to attach a guarantee level to the model behavior. A set of (66) models are considered, from which the adequate VC model for real time (RT) simulation purposes is determined.

A flexible modular type calculation method is developed in this paper, it can be used to a multitude of applications, thus permitting many required turbomachinery systems to be simulated. In this method every standard component is considered as a subsystem, which can be readily linked in diverse ways with other components. This method can also be used for calculating the transients of nonlinear systems under large pertubation. As a case study, a computer programme for simulating the energy recovery system of the fluidized catalytic cracking (FCC) installation is presented.
