摘　　要：提出一种新型的太阳能光伏发电与供热复合循环系统,该复合循环系统有效利用太阳辐射能量,提高光伏系统电池功率,并将光伏电池所产生的热量有效回收,实现同一聚光集热器对外供电、供热。构建了槽式聚光太阳能热电复合循环实验装置,实验表明,在10倍太阳聚光作用下,单晶硅电池功率可放大5.05倍,并可有效回收太阳电池所产生的热量。太阳能热电联供系统能有效提高太阳能综合利用率。A solar combined heat and power cycle sysetm drven by concentraitn trough device was presented in this paper. The solar energy could be efficiently utilized with the combined cycle system, the power of the solar cell can be enhanced and the heat produced by solar cell can be recovered, both the power and heat were provided by the same concentrating trough collector. A experimental combined heating and power device drven by solar concentrating trough were construct- ed. The experimental results show that the power produced by solar cell can increase 4.05 time under 10 solar concen- trating rate, also provide heat relaimed from solar cells effectively. The hybird utilization of solar energy can be reached with combined heat and power sysetm.
