INTRODUCTION IMPROVING the efficiency of power generation equipment and ensuring its reliability are the most important factors in maintaining the reliable supply of electric power on which the infrastructure of society depends. In preparation for greater adoption of renewable energy in the future, it is also essential to establish technologies for connecting this additional generation capacity...

Integration, access, and analyses of streaming data plays an important role in predictive and reactive diagnostics of turbines and other large appliances in Siemens Energy. In this demo we will show how semantic technologies implemented in the ontology-based data access platform OPTIQUE can help in enhancing these tasks. We will demonstrate how to deploy our platform over relational streams, re...

Industrial gas turbines show performance characteristics that distinctly depend on ambient and operating conditions. They are not only influenced by site elevation, ambient temperature, and relative humidity, but also by the speed of the driven equipment, the fuel, and the load conditions. Proper application of gas turbines requires consideration of these factors. This tutorial explains these c...

The solid residue from wood-based ethanol production has a low ash content and high heating value, making it interesting for combustion applications, e.g. small-scale appliances and gas turbines. Combustion and gasification properties have been studied using thermogravimetric analysis (TGA) and differential thermal analysis (DTA). Char combustion rate data obtained could be used in combustion s...

Given the critical nature of gas turbines in most industrial plants, their availability is of prime importance. Associated maintenance costs can also be extremely high and hence, it is a high priority to find ways of reducing maintenance costs and increasing the availability of the gas turbine. Routine preventative maintenance techniques have been used for many years to minimise major problems ...

Increasing concerns about energy and emissions from fuel consumption in gas turbines has attracted many researchers to protect the environment and reduce pollutants in the world. The main objective of this paper is to investigate the increasing efficiency of three-stroke gas turbine operation based on the technical analysis of the operation of three-axis gas turbine cycles with non-design condi...

in this paper, a new combined power and refrigeration cycle is proposed, which combines the rankin power cycle and the ejector refrigeration cycle. this combined cycle produces both power output and refrigeration output simultaneously. this cycle is driven by the flue gas of gas turbines, industrial waste heats, solar energy and geothermal energy. an exergy analysis is performed to guide the th...

Gas turbines are currently a popular power generation technology in countries with access to natural gas resources. However they are very complex systems the operation of which at peak performance is challenging. This paper proposes the use of a hybrid approach based on an Adaptive Neuro-Fuzzy Inference System (ANFIS) for the control of the speed and the exhaust temperature of a gas turbine. Th...

This paper proposes a hybrid possibilistic-probabilistic evaluation tool for analyzing the effect of uncertain power production of distributed generations (DG) on active losses of distribution networks. The considered DG technologies are Gas and wind turbines. This tool is useful for Distribution Network Operators (DNOs) when they are faced with uncertainties which some of them can be modeled p...
