Turbine Analysis
Single Shaft Gas Turbine Simulation
Gas turbine applications are consolidating and growing in the dynamic industrial and production of goods and services of today. The best example is the generation of electric power. Previously, gas turbines covered the range of peak load generation. Nowadays with the progressive increase of the generation limits through gas turbines, these are covering average ranges and in cases of moderate energy demands can cover the base load.
​
In my project for the Thermal Turbomachinery course, given a daily situation of demand for electrical energy, I evaluated the conditions of operation of the equipment such as Power, fuel flow, parameters of the Brayton cycle, operation and performance of the compressor, during the given period of one day, using a commercial software or virtual machine called "Virtual Engine - Single Shaft Gas Turbine".
​
The evaluated gas turbine has a single shaft for electric power generation, is part of a modified Brayton steam injection cycle (STIG, Steam Injected Gas Turbine). The behavior of the cycle was evaluated under three conditions:
1. No modifications of the working fluid regarding the Air Filtration and combustion chamber Water-Fuel ratio.
2. Modifying the humidity conditions of the working fluid, specifically the Inlet Loss in the Air Filtration data
3. Modifying the water-fuel ratio in the combustion chamber.
This project represents a good example of the type of problems posed during the courses of Thermal Turbomachines. Planning is necessary to meet the various types of demand today, therefore, demand studies must be carried out in order to economically cover the electric energy demand without wasting resources.
