摘　　要：针对光热发电系统中太阳能输入的不稳定性,提出了一种能够利用蓄热系统进行多运行模式灵活切换和抑制出力随机波动的光热发电系统。以塔式光热发电系统为例,建立光热发电系统能量转换数学模型,分析光热发电各子系统能量转换机理。进而提出含蓄热的光热电站不同工况下的运行模式,研究多模式下光热发电系统的输出调节特性。利用Matlab软件对建立的模型进行仿真验证,结果表明:光热发电系统可根据不同气象工况运行在不同模式,在保证发电稳定输出的同时,实现出力最大化。For the instability of solar energy input in concentrating solar power system, a concentrating solar power system is proposed, which can use the thermal storage system to switch operation modes flexibly and inhibit output random fluctuations. Taking the tower system as an example, a mathematical model of energy conversion was built, and energy conversion mechanism of each subsystem was analyzed. Furthermore, operation modes under different working conditions were provided to concentrating solar power with thermal storage of solar - thermal power station, and the output regulation characteristics were discussed in various modes. By using Matlab software, the model was simulated and verified The results show that concentrating solar power system can operate in different modes according to different weather conditions, and ensure output stabilization and maximization.
