The use of gas turbines is widespread in several industries such as; hydrocarbons, aerospace, power generation. However, despite to their many advantages, they are subject to multiple exploitation problem that need to be solved. Indeed, the purpose of the present paper is to develop mathematical models of this industrial system using an adaptive fuzzy neural network inference system. Where the ...

Anomaly detection plays a significant role in helping gas turbines run reliably and economically. Considering the collective anomalous data and both sensitivity and robustness of the anomaly detection model, a sequential symbolic anomaly detection method is proposed and applied to the gas turbine fuel system. A structural Finite State Machine is used to evaluate posterior probabilities of obser...

Thermal barrier coating are perceived as an enabling technology to increase the performance of, improve efficiency within, and lower the emissions from, modern gas turbines. To fully utilise this capability one has to be able to accurately predict the life of these coatings under conditions relevant to gas turbine service. This paper addresses the failure of TBC systems as a result of erosion a...

The offshore wind energy market is developing fast. Turbines, substations and offshore sites are increasing in size and they are in more challenging environments. Therefore, the industry requires vigilance in maintaining standards to keep pace with technology developments, enabling safe deployment and long term operation. Certification of wind farms, wind turbines and their components is state-...

We examine the adoption of gas turbine electricity generators by electric utilities and independent power producers, from 1980 to 2001, in search of evidence of economic regulation inducing particular type of technology adoption and development. We focus on three major attributes of gas turbines capacity, heat rate, and age and two major economic regulatory regimes vertically integrated utiliti...

In order to characterize the transient dynamics of steam turbines subsections, in this paper, nonlinear mathematical models are first developed based on the energy balance, thermodynamic principles and semi-empirical equations. Then, the related parameters of developed models are either determined by empirical relations or they are adjusted by applying genetic algorithms (GA) based on experimen...

This paper employs a novel Monte-Carlo based generation portfolio assessment tool to explore the implications of increasing wind penetration and carbon prices within future electricity generation portfolios under considerable uncertainty. This tool combines optimal generation mix techniques with Monte Carlo simulation and portfolio analysis methods to determine expected overall generation costs...
