PURPOSE: A method for calculating a heat balance of electric generation equipments applied for improving efficiency of the Rankine cycle is provided to calculate the heat balance of cooling equipments by receiving information for a turbine inlet condition and a cooling water condition used in a condenser, and sequentially determining the condition for each equipment of the Rankine cycle. CONSTITUTION: Energy increment by a GSC(Gland Steam Condenser) is determined(S50). An exhaust condition of a low pressure heater, a deaerator, a feed-water pump, and a high pressure heater is calculated(S70,S90,S100,S120). The enthalpy for an extraction nozzle to a turbine, the high pressure heater, the deaerator, and the low pressure heater from the turbine is respectively determined by using the exhaust condition(S130-S150). The enthalpy of the turbine exhaust is determined by using the enthalpy(S160). A drain condition of the high/low pressure heater is determined(S170). A heat rate is calculated by using the drain condition(S190). |
