“…Compressor efficiency is a function of manufacturing quality. Different gas turbine has different efficiencies (Torbidoni and Horlock 2006;Dev et al 2014a). Compressor erosion is represented by a lower inlet mass flow capacity and a reduction in compressor isentropic efficiency ).…”

“…Henceforth, to develop a unique representation that is independent of labelling, a permanent function of GTPP system matrix is suggested here. This permanent function is a standard matrix function and is used in combinatorial mathematics (Dev et al 2014a). The permanent function is computed in the same way as determinant but in variable permanent function positive signs replace the negative signs.…”

This paper presents a methodology based on graph theoretic approach (GTA) to design a new gas turbine power plant (GTPP), upgrading of existing plant and evaluation of two real life operating gas turbine power plants. Different combinations may be recommended by a manufacturer to an organization for selecting or improving the thermal efficiency of a power plant. This paper recognizes various design parameters affecting the gas turbine power plant efficiency. All these parameters are interacting with each other by different amounts. An attempt has been made to develop a mathematical model of GTPP from these interacting parameters using GTA. A GTPP efficiency index is proposed which assesses the influence power of these parameters.

The graph theoretical analysis and a graph's characteristic polynomial are deployed as the basis for a system approach employed to develop a model for estimating the reliability index and evaluating the availability index for a coal-fired generating power station. In this research, the coal-fired generating station system is divided into six subsystems. Elementary to evaluating the reliability (estimate) of the said system is the consideration of all the subsystems and their interrelations. Approximate reliability attributes of the graph are used to model the approximate reliability of the coal-fired generating station. Subsystem reliability is represented by the nodes in the graph, and the links represent the reliability of interrelations of these subsystems. Computing a graph's characteristic polynomial using three different methods, namely, the linearly independent cycles, the figure equation and the adjacent matrix, the approximate reliability of the system is determined. Three methods are used, for comparison purposes, as estimating reliability is always an imperfect endeavour. The methodology proposed in this study is illustrated step-by-step with the help of examples.

“…The methodology developed for performance evaluation was extended for the evaluation of reliability and efficiency. Dev et al (2014a) proposed that reliability is dependent upon the sub-systems. It is the reliability of individual components which affect the reliability of macro-system.…”

Unit electricity generation cost from an energy resource such as coal with the help of energy conversion systems such as cogeneration cycle power plant (CGCPP) is dependent upon many of the factors such as (a) system structure which is comprised of layout and design (b) system availability which is further dependent upon maintenance (c) power plant thermal efficiency and other regulatory aspects. These are the parameters which are affecting power plant performance. These are numerous in number and nature. For the complete analysis of cogeneration cycle power plant a multi attribute decision making (MADM) technique is required to study the effect of one parameter on the others. In the present analysis a combination of two mathematical tools graph theory and matrix method is used to develop a methodology to evaluate cogeneration cycle power plant performance. The maximum and minimum value of cogeneration cycle power plant performance index is calculated which indicates the range with in which it can vary. This range can be compared with real time value in order asses the relative performance of the system in real time situation.
