塔式太阳能定日镜安置位的研究

The stow position of heliostats at CSP tower plant

以某实际工程项目为例,计算并模拟了整个镜场中的定日镜当处于安置位时,在全年里每个时刻,反射光斑被动投射至光斑校正目标靶的定日镜的数量以及在镜场中的分布情况。分析了安置位的设计对定日镜光斑校正以及定日镜调试的影响,并给出了调试时期对定日镜安置位设计的建议。研究成果对实际工程中定日镜的调试、安置位的设计和吸热塔的安全有着重要的指导意义。

This paper calculates and simulates the number and layout of heliostats whose reflected beam is passively projected to the beam correction target when they keep the STOW position at each time in a year at a tower concentrating solar power plant.Meanwhile,this paper analyzes the influence of the design of the heliostat STOW position during the commissioning and calibration for the power plant,and gives suggestions for the design of the heliostat STOW position.It has an important guiding significance for the commissioning of heliostats and the design of the heliostat stow position and receiver tower safety in a CSP Tower Plant.
