“…Electric energy is the vital artery for running the daily business of societies in our time. The demand for electricity all over the world is constantly increasing, and the rate of this increase reaches 8% in developed countries and 25% in developing countries [1]. Recent years have been characterized by a high rate of use of bare stations to produce the electrical energy required to cover the load of the electrical network in Iraq, due to the small size of these units relative to the energy produced, which leads to their need for a short time for construction compared to steam units.…”

The main problem of gas turbine generating units operating in the simple cycle system is their relatively low thermal efficiency, which leads to large thermal energy losses. The current research aims to study the economic analysis of Kirkuk gas power plant. Field data of gas turbine unit for the year of 2019 were used. The results of the study showed that the cost of exported energy is higher than the cost of energy produced. The results showed a 23% increase in the cost of energy produced in summer compared to winter. A decrease in actual production compared to the planned production is observed by 12.8%, where the highest actual production for the month of March was 162,108 MW, while the planned was 186,000 MW. Also, the month of July witnessed a very low fuel consumption rate for natural gas compared to the rest of the months, where the average fuel consumption was 0.273 m3/kW, while the month of January has a high fuel consumption rate for natural gas compared to the rest of the year with average fuel consumption of 0.312 m3/kW. The rate of increase in fuel consumption between July and January was 14.2%, and the results also showed that the ratio of production to design capacity for January was the highest and amounted to 87%, and the highest efficiency reached 33%, while July was the lowest production rate in terms of design capacity, reaching 53% and efficiency of 29.8%.

“…The gas turbine parameters are the ones that influence the performance of CCGT significantly [4]. The major influencing gas turbine parameters are compressor pressure ratio, air-fuel ratio, turbine inlet temperature, and isentropic efficiencies of compressor and gas turbine [5,6]. The performance speculation of any energy system is carried out by thermodynamics means.…”

“…Few researchers have studied the effect of the aforementioned gas turbine parameters on this exergy-based performance factor. Ankit et al [6] studied the effect of compressor pressure ratio and isentropic efficiency on the thermal efficiency of the gas turbine cycle. It was observed that increasing the pressure ratio and isentropic efficiency increases the thermal efficiency as per a higher value of the air-fuel ratio.…”

The performance of a combined cycle gas turbine power plant depends on multiple operating parameters, which are influential in distinct ways. These parameters are classified as gas turbine parameters and steam turbine parameters. This paper deals with the influence of two gas turbine operating parameters, i.e., pressure ratio and air-fuel ratio. The 2nd law of thermodynamics has been taken into consideration along with energy analysis to measure the performance of several components of a combined cycle gas turbine plant. Therefore, a comprehensive exergy analysis for each element and the plant has been carried out to overserve the trend of the given range of aforementioned parameters. It is observed from the results that exergy destruction increases in the compressor at a higher-pressure ratio if the compressor is subjected to increased airflow, but exergetic efficiency remains unchanged. Moreover, a similar increment has been observed in the combustion chamber, but the rate of change varies along with the increase in the Air-fuel ratio. For the lower pressure ratios (5-10), the exergy destruction rate for the steam turbine decreases along with increasing in air-fuel proportion, but the effect becomes nearly opposite for the higher-pressure ratios.

In this paper, we will attempt to study a fundamental problem, namely, how gas stations operate worse as the outside temperature rises and production decreases. This examination focused on the gas generator made at the Al-Qayyarah gas station. Based on the data from the station's fourth unit, it was discovered that the two factors that affect the compressor's theoretical efficiency, air temperature entering the device, and compression ratio, are strongly correlated. season is larger than summer because more concentrated energy is generated during the winter, reaching 107.5 MW, whilst concentrated energy production in the summer does not go over 85.8 MW, Due to the cold temperatures, efficiency in the winter was only 29%, while in the summer it was 27.2%.
