Abstract
In recent years, domestic energy policy has continuously changed,
especially, after a liberalization of electric power market opened, resulting into the power industry proprietor expected to has a stable electric power supply systems, high power generation, high thermal efficiency and low heat rate. They will consistently devise a way to propose a strategy of improved or enhanced in the light of a competitive footstone for electric force market.
About 90% worldwide and 65% domestic electricity are generated by the thermal power plants, where the energy source is obtained from burning the fossil fuels. Therefore, Increasing the power generation capacity of thermal power plants will substantially raise to the percent reserve margin of to be smaller than 12% over the years.
In Taiwan, the ambient temperature is always higher than 30oC at summer. When gas turbine has operated during peak, gave rise to deteriorate its power generation capability and often actually generated power lower 10% than based on a design condition of ISO 15oC.
This study adopts a way which is not same as conventional method increased power generation capability of the thermal power plants.
In other word, reducing the inlet air temperature to gas turbine, it will increase the air flow mass rate and the generated-power capacity. By means of EPRI Gate Cycle Software constructing a typical combined-cycle power plant, at the same time, to simulate and to search out an effective operating control strategy for the power plant with GTIAC.
Furthermore, applying the electric chiller and the absorption chiller to combined-cycle power plant as an inlet air cooling system use thermodynamic and engineering analysis to discuss an extent of energy utilizing, the valuability of energy application, to access the economic effect of investing equipment to acquire an optimal balance point.
Selecting the inlet air temperature 15oC,10oC and comparing the thermal performance of electric chiller with that of absorption chiller. Then, proposing a feasible suggestion to treat as an important reference criteration of improving present power GENSET and planning to install a thermal power plant for the electric power proprietor.
