本文根据太阳运动规律推导出定日镜集光系统一系列简易的计算公式,可供设计塔式太阳能热电站时参考。 图1中PP′为通过地球两极的天轴,P为天球的北极;Z为天顶;QEQ′W为垂直于天轴的平面——赤道面,它和春秋二分日太阳周日运动的平面重合; In this paper, a series of simple formulas for heliostat collecting system are deduced according to the law of solar movement, which can be used for reference when designing tower solar thermal power station. In Figure 1, PP ’is the axis of the Earth’s poles, P is the North Pole of the celestial sphere, Z is the zenith, QEQ’W is the plane perpendicular to the axis of the sky, the equatorial plane. coincide;
