Thermoeconomic Analysis Of 600MW Unit On The Basis Of Structural Theory

Exergy analysis and thermoeconomic analysis of 600MW unit was carried out on the basis of available achievements in this paper. The main contents include: Thermoeconomic cost model was established using structural theory. Exergy analysis and thermoeconomic analysis were carried out under variable conditions and energy saving potential component was pointed out according to indicators ; the composition of unit exergy cost and unit thermoeconomic cost were analyzed quantitatively, pointing out the reasons for the high cost of components and the possibility to reduce cost; the variation of thermoeconomic indicators under variable conditions was analyzed, also the unit exergy costs of feed water heater and steam turbine were compared; the influence of the external fuel prices and the growth of equipment investment was studied. The reasons leading to increased cost of electricity was analyzed deeply; The calculation software of thermoeconomic cost was established using VC++language.
