[Abstract]:Solar assisted coal-fired power generation system can realize the coupling of solar thermal energy and traditional thermal power production, reduce the coal consumption of traditional thermal power generation process, and promote the energy saving and emission reduction of power production process. This paper mainly studies the energy distribution characteristics and optimization potential of channel solar assisted coal-fired power generation system. The main research contents and results are as follows: Firstly, the basic model of the solar assisted coal-fired power generation system is established according to the working characteristics of the trough solar energy gathering field and the operation characteristics of each equipment of a certain 330MW thermal generating unit, and the model is verified. The accuracy of the model is determined as the basis for further analysis and calculation. Secondly, based on the second law of thermodynamics, the paper analyzes the solar assisted coal-fired power generation system under different operating loads. The energy distribution and utilization of the system are obtained and compared with that of the traditional thermal generator set. The distribution characteristics are analyzed and compared, and the power generation system with solar energy coupling is determined. Be able to take advantage of advantages. Thirdly, the thesis is in the traditional form. On the basis of the analysis method, the solar auxiliary coal-fired power generation system is inevitably adopted. Loss analysis, where the equipment of the power generation system is known According to the characteristics of the related equipments, this paper analyzes each equipment on the premise of its utilization. The damaged parts can be redeveloped and utilized, which provides a certain reference for the optimization and transformation of the system. Finally, the solar assisted coal-fired power generation system can be used in this paper. Economic performance analysis, and on this premise, combined with the inevitable) The loss analysis method is applied to the system. Based on the analysis of the economic performance of the loss, the priority of each equipment in the solar assisted coal-fired power generation system is determined, which is the basis of the equipment operation and investment optimization.
