The current research is aimed at carrying out an exergy analysis of a 33-MW gas turbine power plant that operates on the Brayton cycle. Quantitative exergy analysis for each component and for the whole system was done. Based on the exergy balance models developed, a computer program is written which is used to investigate the performance of the power plant under varying ambient and turbine inle...

In order to meet increasing power demand, taking into account economical and environmental factors, wind energy conversion is gradually gaining interest as a suitable source of renewable energy. In this paper, The modeling of the Wind Energy Conversion System (WECS) with Matrix converter i s p r o p o s e d . The matrix converter, as a power electronic converter, is used to interface the induct...

The main objective of the paper is to develop a probabilistic model for capacity factor estimation for a wind turbine located in a specific area, model based on the output power distribution of wind turbine. This model was applied for a wind turbine located to a region in the North-East of Romania, the model results being validate with results from Monte-Carlo simulation. Finally, the model was...

This paper concentrates on the modeling and control of distributed generation systems including fuel cell and gas turbine. The fuel cell is onnected to the power system through a dc/ac converter, which is equipped with both voltageand power-control loops. The gas turbine is also ssumed to be equipped with both voltage-control and generation (or frequency)-control loops. Moreover the gas turbine...

In this study, a field testing has been carried out to assess the power characteristics of some small scale wind turbines fabricated by one native technician from Tanzania. Two Horizontal Axis Wind Turbines (HAWTs), one with five and other with sixteen blades were installed at a height of 2.4m above the ground. The rotation speed of the rotor blade and wind speed approaching the turbines were m...

This paper shows an improvisation for gas turbine power plants. It incorporates a hydraulic compressor to compress air prior to combustion. The aim is to reduce in-house consumption of the power generated in the turbine, thus increasing the overall efficiency of the power plant. The proposed compressor could also be used in different scenarios.
