Performance evaluation of solar aided coal fired power plant using structural theory of thermoeconomic

摘要

The structural theory of thermoeconomic is applied to a hybrid system named Solar Aided Coal Fired Power Plant (SACFPP) where solar energy is combined to a 600 MW coal-fired system using the way of taking place the high pressure bled steam feed heater.Based on Fuel-Product concept of structural theory,the performance of components and the interaction between them were evaluated.The performance of components at design condition of solar aided coal fired power plant are evaluated by the way of system simulation.The results prove that the Structural Theory is a useful tool of complex energy system and the solar aided coal-fired power plant can use the solar energy efficiently.
