  • Research on the Performance of Coal-Fired Power System Integrated with Solar Energy
    Energy Procedia, 2014
    Co-Authors: Wu Junjie, Hou Hongjuan, Yang Yongping
    Abstract:

    Integrating solar energy into conventional Coal-Fired power system provides a way to overcome the inherit shortcomings of solar energy, such as intermittent and instability. In this paper, a coupling analysis of the solar field, turbine and boiler is made and Matrix Thermal Balance Equations is introduced in the calculation of the system SAPG. For a system SAPG running in coal-saving mode with constant load, the result shows that the introduction of solar field into Coal-Fired Unit leads to mass flow rate variation and temperature drop of superheat steam and reheat steam greatly. As a result, more consumption will be needed if too much power is provided by the solar field.

  • performance evaluation of solar aided feedwater heating of coal fired power generation safhcpg system under different operating conditions
    Applied Energy, 2013
    Co-Authors: Hou Hongjuan, Yang Yongping, Yu Zhenyue, Wu Junjie
    Abstract:

    Abstract Integrating solar energy with a Coal-Fired power plant or other power systems has been proved to be an efficient way to utilize solar energy for power generation. Solar aided feedwater heating of a Coal-Fired power generation (SAFHCPG) system, which is mainly discussed in this paper, is chosen as an option for its easy operation and flexible control nature. The performance of a SAFHCPG system at design point is analyzed under various load conditions in the paper. As the results show in Table 4 , the lower load of Coal-Fired Unit that solar aid, the lower solar-to-electric efficiency will be. For a SAFHCPG system, its performance is influenced by the solar radiation intensity and the electrical load demand on the grid side. The correlation between the annual performance of a SAFHCPG plant and the two key factors is discussed and then the optimal aperture area of solar field is derived. The result shows that, for the case studied the optimal aperture area of solar field and the lowest LEC (Levelized Electricity Costs) are: 115395 m2 and 0.472 ¥/kW h in a typical year; 138945 m2 and 1.010 ¥/kW h in an extremely low radiation year; 91845 m2 and 0.426 ¥/kW h in an extremely high radiation year respectively.
