This study proposed a model-based robust fault detection (RFD) method using soft computing techniques. Robust detection of the possible realistic incipient faults of an industrial gas turbine engine in steady-state conditions is mainly centered. For residual generation a bank of Multi-Layer perceptron (MLP) models, is used, Moreover, in fault detection phase, a passive approach based on Modelli...

The World Wide Web has emerged as an effective mechanism for distributing educational material to students beyond the bounds of the classroom. The introduction of mobile code, such as Java applets, combined with the pervasiveness of the World Wide Web, present the potential to significantly enhance the development and distribution of educational software. This paper illustrates the design and ...

This paper introduces a fuzzy sensor validation and fusion methodology and applies it to sensor data from a gas turbine power plant. The FUSVAF (Fuzzy Sensor Validation and Fusion) algorithm tackles two problems: (1) It filters out noise from measurements provided as input to a gas turbine controller to maximize power plant performance. (2) It compensates for sensor failure to allow the power p...

Recently, we have completed the development of an The ability to obtain quantitative planar laserincorporates a production fuel injector and is capable of induced fluorescence (PLIF) measurements in a highoperating at pressures up to 50 atm with preheated air. pressure combustor would represent a significant This facility allows laser-based imaging techniques to be advance in the application of...

In this paper, the statistical analyses are presented to study the thermal efficiency and power output of gas turbine (GT) power plants. For analyzing gas turbine operation and performance, a novel approach is developed utilizing the response surface methodology (RSM) which is based on the central composite design (CCD) method. An attempt is made to study the effect of some operational factors ...

A steam turbine, heart of all refineries. This work presents the mathematical modelling of the steam turbine unit in isolated operating condition, based on the continuity equation including servomotor for actuation purpose. Steam turbine should run at a constant speed for its safe operation and frequency stability. Adaptation of different controller like Feedback, PI, PID using certain adaptati...

Comprehensive upgrades of gas turbine involve the replacement of “flange-to-flange” parts with more advanced designs. Because late-model gas turbines already incorporate advanced technology, these comprehensive upgrades apply only to older gas turbines that are part of a series or model line that the original equipment manufacturer (OEM) has redesigned. Examples of these model lines include the...

The paper is devoted to solution of some problems in nuclear power station generating unit intellectual control systems using genetic algorithms on the basis of control system model development, optimizations methods of their direct quality indices and improved integral quadratic estimates. Some mathematical vector models were obtained for control system multicriterion quality indices with due ...

This paper develops a health monitoring scheme to detect and trend degradation in dynamic systems that are characterised by multiple parameter time-series data. The presented scheme provides early detection of degradation and ability to score its significance in order to inform maintenance planning and consequently reduce disruption. Non-parametric statistics are proposed to provide this early ...
