This research performs the advanced exergy and exergoeconomic analyses of a combined cycle power plant (CCPP) located in Zavareh, Iran. The objective of this research is to evaluate the irreversibilities, their related cost rates of each part of the CCPP that can be avoided and the inefficiencies of each part that caused by other components. The advanced exergy and exergoeconomic analyses indic...

Introduction: Exposure to the low frequency electric and magnetic fields (ELF-EMF) is very common in workers occupied in the combined cycle power plant during work shifts  The present study aimed to measure ELF-EMF flux density among shift and non-shift workers, determine job stress among workers and office workers, and identify major factors associated with job stress in the studied groups. M...

Simulators for power plants can be used for many different purposes, like training for operators or for adjusting control systems, where the main objective is to perform a realistic behaviour for different operating conditions of the power plant. Due to an increased amount of variable energy sources in the power system, the role of the operators has become more important. It can therefore be ve...

The aim of this paper is the description of two simulation models that have been realized in the Matlab/Simulink environment in order to study the heat transfer in the metal and insulation parts of steam drums belonging to heat recovery steam generators located in combined cycle power plants. Both simulators derive from a finite differences model based on the discretization of the Fourier’s hea...

in this paper the effect of site conditions, which are altitude, temperature and relative humidity and also heat dissipation capacity are investigated on the optimized design of natural draft dry cooling towers with specific kind of heat exchangers, known as forgo t60 type. a genetic algorithm program has been developed for optimized design of these cooling towers. objective function includes b...

This extended abstract presents a decision support system based on decision-theoretic planning techniques. Its goal is to provide power plant operators with useful recommendations to (i) maintain a plant running under safe conditions, and (ii) to deal with process transients when an unexpected event occurs. We use the formalism of partially observable Markov decision processes as the core of an...

The combined cycle power plant is made up of three major systems, the gas turbine engine, the heat recovery steam generator and the steam turbine. Of the major systems the gas turbine engine is a fixed design offered by a manufacturer, and the steam turbine is also a fairly standard design available from a manufacturer, but it may be somewhat customized for the project. In contrast, the heat re...

This paper reviews the limits of the traditional ‘levelised cost’ approach to properly take into account risks and uncertainties when valuing different power generation technologies. We introduce a probabilistic valuation model of investment in three base-load technologies (combined cycle gas turbine, coal plant, and nuclear power plant), and demonstrate using three case studies how such a prob...
