摘要:

为降低塔式光热电站的成本电价,需要合理设计吸热器中心高度以优化电站效率。对某100 MW塔式太阳能光热发电站吸热器中心高度的优化方法和思路进行了研究。通过建模,模拟了不同吸热器中心高度与定日镜数量的关系及对电站发电量的影响,通过成本电价寻优的方式确定吸热器中心高度。分析结果发现,不同高度的吸热器中心高度的增加,成本电价存在最低值。基于一定规模的储热容量,该热发电站吸热塔高设计为220 m时,成本电价最低。通过优化热发电站吸热塔高度,可降低项目投资的成本、提高项目经济性。

Abstract:

In order to reduce the power generation cost of solar power tower plants, center heights of the receivers should be optimized for stations' efficiency improvement. The optimization method for the receiver's central height in a 100 MW solar power tower plant was investigated. The influences of the receiver's height on the quantity of heliostats and the power plant output were simulated after model construction. The height of the receiver was obtained by the minimum power generation cost method. The results show that, with the increase of the receiver's height, power generation cost will touch bottom. With a certain heat storage capacity, the power generation cost can bottom out with a receiver tower height at 220 m. By the means of optimizing receiver towers height, the investment cost can be reduced and the economy can be improved.

Key words: solar power tower plant, receiver, heliostat, solar collection field, power generation cost, heat storage
