Abstract

Gas turbine units are widely used in KSA and other countries particularly during the peak demands and in inland regions. They produce about 50% of the total capacity of power generation in the kingdom. Despite their numerous advantages, their thermal efficiency remains very low and their resulting environmental impacts are significant. In this study, the effect of ambient conditions on the performance of a typical gas turbine used in KSA has been studied theoretically using the average hourly temperature and relative humidity for three regions of the country (Eastern, Central, and Western) which have almost the same power demand. Mass and energy balance equations with typical and realistic specifications of power plant units have been used to develop the model. The results present time variations of power generation, fuel consumption and efficiency for several typical cities. The maximum monthly power loss due to weather variation in Riyadh, Ad Dammam, and Jeddah are estimated at 8.9, 9.41 and 9.32 GWh respectively. While the annual power production loss in Riyadh, Ad Dammam, and Jeddah are 7.1, 8.2, and 11.2%, respectively. Power generation increases to about 4220 and 3028 kW when inlet air is cooled to 8.9 and 10.15oC, respectively. In conclusion, the effect of weather conditions of several Saudi areas on the performance of gas turbine units is significant. Therefore, the incorporation of inlet cooling technologies should be considered seriously.
