Abstract:
1. A plant operation support system supporting operation of a plant including a thermal power generation facility and a carbon dioxide recovery facility which uses thermal energy and electrical power from the thermal power generation facility, the plant operation support system comprising: a condition setting unit setting a power supply amount to be supplied from the plant to an outside and a target recovery rate of carbon dioxide to be generated by the thermal power generation facility; a characteristic data storage unit storing characteristic data representing a capability of recovering carbon dioxide by the carbon dioxide recovery facility, the capability varying according to operating output of the thermal power generation facility; and a predicting unit predicting a fuel consumption amount in the thermal power generation facility and a recovery amount of carbon dioxide in the carbon dioxide recovery facility based on contents set by the condition setting unit and contents stored in the characteristic data storage unit, wherein the predicting unit sets an assumed value of a generator total output amount based on the set power supply amount, the generator total output amount representing a sum of an electric power amount generated by the thermal power generation facility and a thermal energy amount supplied from the thermal power generation facility to the carbon dioxide recovery facility, the predicting unit determines an operating output of the thermal power generation facility corresponding to the assumed value, the predicting unit obtains a necessary heat quantity and a necessary power amount corresponding to the determined operating output and the target recovery rate based on the characteristic data, the predicting unit obtains a heat efficacy based on the determined operating output and the characteristic data, the predicting unit calculates the generator total output amount based on the necessary heat quantity, the necessary power, and the heat efficacy, the predicting unit compares the calculated generator total output amount with the assumed value to verify the calculated generator total output, the predicting unit obtains the fuel consumption amount and the recovery amount of carbon dioxide based on the verified generator total output amount.
