摘要
为确定光煤互补系统中太阳能辅助发电系统的适配容量,通过计算得到在不同光热流量占比下光煤互补系统的全厂热耗量,对2个热源耦合输入系统进行定量分析,计算耦合及解耦后运行时的双源输入焓,确定互补方案下不同运行模式下光热辅助系统的发电热耗量及其储热系统所需的熔融盐需求量,通过Ebsilon软件仿真模拟得到不同光热流量占比中,与互补系统解耦运行后的单一太阳能辅助发电系统的估计最大装机容量为16.965 MW,最后得到互补系统在节煤型方案3种工况运行下所能达到的节煤量。
In order to confirm the adaptive capacity of the solar auxiliary power generation system in the light-coal complementation system,this paper calculated the heat consumption of the light-coal complementation system across the plant under the different percentage of solar-thermal flow and then conducted quantitative analysis on the coupling input system of these two heat resources to compute the dual-source input enthalpy after coupling and decoupling,so as to ascertain the heat consumption of the auxiliary power system for electricity generation and the amount of molten salt demanded by its thermal storage system under different operation modes.Meanwhile,by utilizing the Ebsilon software simulation,this paper obtained that the estimated maximum installed capacity of the single solar auxiliary power generation system while running the complementation system after decoupling was 16.965 MW under the different percentage of solar-thermal flow.finally,the coal-saving amount of running the light-coal complementation system under three operating conditions set by the coal-saving solutions could be obtained.
