摘要：

太阳能光煤互补电站将太阳能热电站与常规燃煤电站相结合，可以实现太阳能规模化、产业化应用。光煤互补电站由于省去了太阳能直接热发电站中必备的汽轮机、发电机系统，克服了太阳能直接热发电站具有的投资高、负荷不稳定等劣势，使得太阳能热量在常规燃煤火电热力系统中以补充的方式发挥作用，同时依靠火电热力系统的强大热源，规避了太阳能直接热发电系统频繁起停等可能引起运行稳定、安全的不足。基于所建立的太阳能光煤互补示范电站分析模型，研究配建储能系统的示范电站在典型气象条件与负荷工况下，电站光场与储能部分运行模式，并定量分析系统调节阀门组的流量分配特性，为实际电站运行规程确定及运行优化研究提供参考。

Abstract:

Sola/coal hybrid power plant integrates solar energy and conventional coal-fired power plant to achieve the scale, industrial application of solar energy. The system reduces the investment of steam turbine and generator, which are necessary in traditional solar thermal power plants, so it has characteristics of lower cost and steady load. Solar energy can act as supplement energy to the thermal system of conventional coal-fired power plant, which can also avoid the unstable and unsafe operation of solar thermal power plant caused by frequently starting and stopping, by relying on the strong heat source of thermal system. Based on the analysis model of the established sola/coal hybrid demonstration power plant, the operation mode of solar field and thermal storage in the demonstration power plant were studied under typical climate and designed condition, as well as the flow distribution characteristics of regulating valve group were quantitatively analyzed, whose results could provide references for real operation rules and optimization in the future.
