  1. 1. Component State Prediction Based on Field Data : Master Thesis in Energy System Engineering

    University essay from

    Author : Linnea Johansson; [2017]
    Keywords : Gas Turbine; Prediction Model; Failure model; Field data; Environmental attributes; Weibull Distribution; Bayesian Statistics;

    Abstract : This master thesis is part of a big project at Siemens Industrial Turbomachinery (SIT) in Finspång aimed to use the operation experience available at SIT to predict the state of the gas turbines in general and some mechanical components in particular. The objective of the thesis is to continue the development of a prediction model based on experience data for estimations of a components lifetime. READ MORE

  2. 2. Simulation of Gas Channel Temperatures during Transients for SGT-800

    University essay from Lunds universitet/Institutionen för Energivetenskaper

    Author : Tobias Johansson; [2016]
    Keywords : Technology and Engineering;

    Abstract : Siemens Industrial Turbomachinery has developed dynamic gas turbine models to compute performance parameters such as temperature, pressure, mass flow and power during transients. Results from the current dynamic model correspond to measured data except for gas channel temperatures that change too fast during transients. READ MORE

  3. 3. Survival analysis of gas turbine components

    University essay from Linköpings universitet/Statistik

    Author : Alessandro Olivi; [2016]
    Keywords : Bayesian Weibull regression; failure modes; optimal replacement time; reliability; survival analysis;

    Abstract : Survival analysis is applied on mechanical components installed in gas turbines. We use field experience data collected from repair inspection reports. These data are highly censored since the exact time-to-event is unknown. We only know that it lies before or after the repair inspection time. READ MORE

  4. 4. Volumetric Solar Receiver for a Parabolic Dish and Micro-Gas Turbine system : Design, modelling and validation using Multi-Objective Optimization

    University essay from KTH/Kraft- och värmeteknologi

    Author : Roberta Mancini; [2015]
    Keywords : volumetric receiver; parabolic dish; OMSoP; micro-gas turbine; multi-objective optimization; ray tracing;

    Abstract : Concentrated Solar Power (CSP) constitutes one suitable solution for exploiting solar resources for power generation. In this context, parabolic dish systems concentrate the solar radiation onto a point focusing receiver for small-scale power production. READ MORE

  5. 5. Comprehensive Analysis of Organic Rankine Cycles for Waste heat recovery applications in Gas Turbines and IC Engines

    University essay from KTH/Elkraftteknik

    Author : Alejandro Tristan; [2014]
    Keywords : ;

    Abstract : Executive SummaryThis investigation aimed to assess the true technical and environmental potential, plus economic feasibility of the ORC technology as bottoming cycles for Gas turbines and IC Engines power applications.The assessment started by creating a modeling tool using the software EES in order to model several bottoming cycle configurations and match them with the mentioned power generation technologies.
