摘 要:基于槽式太阳能热发电技术特点,综述带熔融盐储热系统的槽式太阳能热发电技术系统流程,提出太阳倍数及储热时间是影响槽式太阳能热发电站经济性的关键因素。提出槽式太阳能热发电项目供电量与太阳倍数(SM)和储热时间的关系,并给出项目年利用小时数与太阳倍数的简化计算公式。依托内蒙古鄂尔多斯地区太阳能资源条件,以50 MW装机规模为基础,分析了项目供电量随太阳倍数、储热时间的变化关系,并依据此计算了50 MW项目投资水平及项目电价水平随太阳倍数及储热时间的变化趋势,为工程设计中技术经济优化奠定基础。
Based on the parabolic trough solar thermal power technology characteristics, overviewed the principle of parabolic trough solar thermal power technology with molten salt thermal energy storage system. The relation between electric-power supplied and solar multiple(SM) and thermal energy storage capacity have been proposed, the project utilization hours simplified calculation formula have been given. Relying on the solar energy resources of Ordos Inner Mongolia, and based on 50 MW power capacity, analyzes the relation between the electric-power supplied and SM and thermal energy storage capacity, calculates the investment level. The relation between LCOE and SM and thermal energy storage capacity has been given.
