Study On The Integration Characteristics Of Coal Fired Power Plant Integrated With The PTCS And TSCS

In recent years,China has become the largest carbon emissions country,combusting a large number of fossil fuels,not only facing the international emission reduction pressure,but also the pollution of the environment has a negative impact on the people health and production.The development of renewable energy power generation,balancing energy consumption structure,is always a national policy.With the investment of resources in research institutes and companies,the solar thermal power generation will become a new way of generation.Because of the thermal storage technology is immature and the initial construction cost is high,the traditional solar thermal power generation,compared with conventional power generation,has no commercial competitive advantage.This paper,based on the 1000 MW coal-fired power plant,uses commercial software Ebsilon Professional to study the integrated solar energy potential of the basic coal-fired power plant in the different integrations.Using the data of the largest integrated solar capacity to guide the thermal complementary integration and study the thermal performance of solar thermal utilization for the next step.In coal-fired power plant system integrated with solar energy,the effects on the operation of coal-fired power plant is taken into consideration,thus control strategy which coal-fired power plant has been taken is considered in the progress of simulation.In different integrated schemes,the thermodynamic properties of different integrations are analyzed from the first law of thermodynamics and the second law of thermodynamics,which can be taken reference for proposing new power generation system.Economic analysis has been studied in this paper about the proposed integrated schemes,and the results shows new power generation systems have a great competition advantage when compared with the photo-thermal benchmark price.What's more,coal-fired power plant integrated with parabolic trough heat collector system and tower heat collector system,has showed significant thermodynamic advantages and economic advantages...
