Abstract: In order to decrease the operation cost in power plants,a 1000 MW coal-fired power plant is studied as the research objective,and an evaluation model about unit thermoeconomic cost is built based on the thermoeconomic theory.By using the Matlab calculation tool,the thermoeconomic optimization of the energy system about the plant is presented.The results show that it is necessary to update the correlated equipment to increase its exergetic efficiency in the design of the entry unit.Moreover,the exergetic efficiency of the boiler is close to the optimum value,as for the steam turbine,its efficiency can be increased with the technical improvement.
