下面结合实施例对本发明进行进一歩的详细说明。
图 1是本发明的太阳能聚集系统的第一实施例的结构示意图。 如图 1所 示， 包括至少 1组菲涅尔反射主聚光装置、 置于菲涅尔反射主聚光装置聚光 方向上的接收装置 103 ; 所述每组菲涅尔反射主聚光装置为 4轴或以上东西 轴布置的反射镜阵列组 101 ; 多片反射镜例如反射镜 110和反射镜 112; 所述 菲涅尔反射主聚光装置的阵列平面向阳坡面倾斜布置； 接收装置 103位于反 射镜阵列组 101的上方， 布置于支撑架 109的上部位置； 太阳能聚集系统整 体的向阳坡面倾斜布置的倾斜角度范围为 15〜50°; 倾斜角度一般大于 20° ， 此时， 反射镜阵列组 101易安装并且具有良好的截光能力， 与普通平铺地面 的菲涅尔阵列单位镜面相比， 其接收能力可增加 20%〜30% 。
该太阳能聚集系统适用于高纬度地区， 例如纬度范围 30〜50° 。 优选地， 太阳能聚集系统整体的倾斜角度范围为 15〜50°， 倾斜角度例如在北京区域优 选为 30° ， 具有良好的综合成本、 安装和截光效果。 各组的所述菲涅尔反射 主聚光装置间距 B为菲涅尔反射主聚光装置的反射镜阵列组宽度 A的 0.6〜2 倍， 以增加整体镜场的有效截光面积或效率。 其中， 反射镜阵列组宽度 A定 义为菲涅尔反射主聚光装置的反射镜阵列组最起始镜条的外边缘到最末端镜 条的外边缘的最大轮廓尺寸连线长度。 主聚光装置间距 B定义为最大轮廓尺 寸连线长度的状态时， 前一组菲涅尔反射主聚光装置的反射镜阵列组的后沿 与后一组菲涅尔反射主聚光装置的反射镜阵列组的前沿之间的地面垂直投影 距离。 菲涅尔反射主聚光装置的汇聚光线夹角小于 90° ， 优选地小于 60° ， 最优地小于 45 ° ， 其中汇聚光线夹角定义为以菲涅尔反射主聚光装置的反射 镜阵列组宽度 A为底边、 接收装置中心点为顶点形成的顶角 α ; 汇聚光线夹 角越小接收装置越容易接收汇聚光， 具有更高的容差性能； 菲涅尔反射主聚 光装置为多个反射镜阵列组， 反射镜阵列组由阵列的镜条组成 （镜条为单个 轴向布置的反射镜阵列， 各镜条包括多个沿轴向布置的反射镜） ， 镜条为一 维弧形柱面， 具有良好的汇聚效果。 优选地， 所述反射镜阵列组的镜条为一 维圆弧形柱面， 方便加工。
反射镜阵列组 101的镜条轴数 （或条数） 为 10轴以内。 优选地， 所述反 镜阵列组的镜条轴数（或条数）为 6轴以内， 以简化系统的建设。 进一歩地， 所述反射镜的镜面可竖立或近似竖立， 处于防冰雹状态。 进一歩地， 所述反 射镜的镜面为非钢化玻璃镜， 在保证强度的前提下， 减少反射镜的制造成本。
太阳能聚集系统的接收装置 103包括二次光学装置， 如二次复合抛物聚 光装置 CPC 或光线转向反射镜或波长分光镜等， 将未直接入射到接收装置 103 内部的接收器表面的太阳光再次反射至接收器外表面； 当接收器为光热 集热器 （图 1 中没有标注） 时， 太阳能聚集系统将太阳能转换成热量后， 推 动热机进行光热发电；该太阳能聚集系统除了可以应用于太阳能光热发电外， 还可以应用于太阳能光伏发电， 即接收装置为光伏接收装置时， 光伏电池组 作为接收器实施光伏发电。 也就是说， 本发明实施例中光伏电池装置或者光 热集热器可以单独作为接收装置使用。该太阳能聚集系统可以布置于屋顶上， 与屋顶倾斜面形成完整的整体。
图 2是本发明的太阳能聚集系统的第二实施例的结构示意图。 如图 2所 示， 包括至少 1组菲涅尔反射主聚光装置、 置于菲涅尔反射主聚光装置聚光 方向上的接收装置 203 ; 所述每组菲涅尔反射主聚光装置为 4轴或以上东西 轴布置的反射镜阵列组 201和反射镜阵列组 202; 所述菲涅尔反射主聚光装 置的阵列平面向阳坡面倾斜布置； 以反射镜阵列组 201为例进行描述， 反射 镜阵列组 201沿东西轴方向向阳坡面倾斜布置， 倾斜角度优选为 30° ， 以保 证太阳能聚集系统安装简易， 并且能够拥有良好的截光能力。 该太阳能聚集 系统适用于高纬度地区， 例如纬度范围 20〜50° 。 太阳能聚集系统的接收装 置 203包括光伏电池装置 221、 光热集热器 224和二者之间布置的波长分光 装置 225 ; 该波长分光装置 225， 可以采用波长分光薄膜分光镜对汇聚的入射 光进行透射、 反射选择分光； 波长分光装置 225也采用棱镜分光镜或棱镜分 光镜组对入射光进行折射选择波长分光；整体实施高效太阳能光谱分离利用， 提高光伏电池发电效率 （减少低光谱响应率范围内光谱的接收， 即减少了能 量向热量的转化， 保证光伏电池高效发电及理想工作温度） 。 如图 2所示， 该太阳能聚集系统布置于旋转平台 209之上， 例如反射镜阵列组 201和反射 镜阵列组 202布置在旋转平台 209上， 多个该太阳能聚集系统布置于同一个 旋转平台 209之上， 共同完成旋转方位角度一个维度上的跟踪， 同时不同的 太阳能聚集系统中的镜面独自摆转完成高度方向的跟踪， 完成另一维度上的 跟踪， 二者共同完成二维跟踪， 获得更加优良的单位面积镜面截光能量； 大 约较一维摆转的该太阳能聚集系统效率提高 15%左右。
图 3是槽式、菲涅尔和本实施例装置各月平均截光能力的累计图。如图 3 所示， 图中每月份均对应一个由 3个柱状图组成的柱状图组， 各柱状图组中 靠近 Y轴的灰色柱状图表示传统槽式集热器系统全年各月单位面积镜面接收 能量的累计； 位于中部的黑色柱状图表示传统菲涅尔集热器系统全年各月单 位面积镜面接收能量的累计； 远离 Y轴的白色柱状图表示为本实施例的聚集 系统全年各月单位面积镜面接收能量的累计。传统槽式集热器系统在冬季时， 各月单位镜面接收能量较少； 夏季时， 单位面积镜面接受能量较多， 冬季和 夏季相差较大， 各月发电量不均匀； 传统菲涅尔集热器系统在全年各月单位 面积镜面接收的能量都较少， 整体镜面效率普遍较低； 本实施例的聚集系统 在冬季时各月单位面积镜面接收的能量较传统槽式要多， 而在夏季时， 各月 单位镜面接收的能量较槽式要稍少， 整体全年接收较为平均， 方便电量上网 并满足了用户需求； 再者， 考虑到光热系统的存储容量， 传统槽式因为各月 相差较大， 并不方便匹配， 当储能量较大时， 例如可以满足夏日的储热， 但 到冬天时， 存储容量严重不足不能满足储热罐容量设计； 当将存储容量设计 为中等水平时， 夏天的储能量不得不有部分弃热， 造成不小的浪费； 该系统 冬天和夏天对应接收的能量相差很少， 方便储热罐存储容量的合理设计和用 户并网的合理需求。
南北轴向布置的菲涅尔聚集系统， 因其平铺地面， 当入射角度小时， 相 邻反射镜的镜条之间容易出现遮光； 当入射角度大时相邻反射镜的镜条之间 容易出现漏光； 而本实施例中， 东西轴布置的反射镜阵列组整体向阳坡面倾 斜布置， 例如在北半球上， 反射镜阵列组向阳坡面倾斜布置， 多个反射镜阵 列组迎向太阳南面进行截光接收； 多个反射镜的镜条之间遮光很少， 漏光也 较南北轴布置的反射镜阵列组要少； 如此整体上南北轴布置的菲涅尔反射镜 结构单位面积反射镜接收能量小于东西轴布置的菲涅尔反射镜阵列组单位面 积反射镜接收能量， 二者全年累计平均大约相差 25%〜30%左右； 传统的南北 轴布置的槽式聚集系统的两个相临槽式的空挡间距大约为抛物槽开口宽度的 1.5倍， 例如抛物槽开口宽度为 6m; 两个相邻的抛物槽中心距为 15m; 空挡 间距为 9m; 在早上 Ί点至晚上 17点时间段接收太阳光形成的遮光有限， 所 以单位面积镜片的接收能力相对要强； 假定槽式南北轴布置反射镜完成一维 跟踪后的入射反射镜槽的入射角度为 Θ 1 : 其中 sin Θ ^cosh^cos γ； 对应的余 弦值为 cos e ^l-cos ^cos^ 15; 实施例一的东西轴布置的反射镜阵列组整 体向阳坡面倾斜角度 45 ° ， 其东西轴布置完成一维跟踪后的入射角度为 θ 2 : 其中 sin Θ 2=C0Sh*sin γ； 对应的余弦值为 cos Θ 2=(l-COS 2h*sin2 γ )。·5; 其中 h 为太阳光线的高度角度， Y为太阳光线的方位角度。 在夏天时方位角度 Y范 围很宽可为 -90 ° 〜90 ° ， 方位角度余弦值小于方位角度的正弦值， 所以传统 槽式在夏天的单位面积镜面接收能量要大； 而在冬天太阳升起方位角度 Y范 围可能为 -60° 〜60° ， 又因为方位角度越小越靠近中午， 而中午的 DNI要比 早上或傍晚的 DNI大， 因此在冬天东西轴布置的反射镜阵列组单位面积镜面 接收能量要大于传统槽式南北轴单位面积镜面接收能量。
该太阳能聚集系统结构上具有很大的优势， 成本较一般的框架低一半， 冬季可以吸收更多的能量， 适于高纬度应用， 可应用于太阳能光热发电系统 ( CSP ) 中， 也可以应用于太阳能聚光光伏发电系统 （LCPV) 中。
显而易见， 在不偏离本发明的真实精神和范围的前提下， 在此描述的本 发明可以有许多变化。 因此， 所有对于本领域技术人员来说显而易见的改变， 都应包括在本权利要求书所涵盖的范围之内。 本发明所要求保护的范围仅由 所述的权利要求书进行限定。
