Abstract :
Gas turbine power plants, when compared to other power plants, due to their low investment cost, fast load change characteristic, low installation time and releasing low harmful emissions with respect to coal fired power plants, in our country, especially with the support of private sector, were established and currently operate. According to 2030 electricity consumption projections, it is approximately twice of 2008 consumed electricity. On the other hand, power plants performance can be increased by taking some performance augmenter precautions and determine the best installation place for new ones. Ambient temperature, pressure and relative humidity in the air have a great effect on a plant performance. Therefore, the installation place of the gas turbine power plants should be chosen the most efficient energy conversion and the minimum payback time. In this study, in a gas turbine power plant, which is thought to be installed in Adana or Ankara, the effects of the environmental temperature, pressure and relative humidity is examined. Also, the effects of inlet air cooling on system performance are examined and by using payback period the appropriate installation place is determined. As a result of economical analysis on the base of payback time evaporative inlet air cooling application takes 257 days for Ankara conditions and 81 days for Adana conditions.
