摘要:

建立太阳能温差发电系统的数学模型,利用温差发电技术将太阳能直接转化为电能.考虑冷却系统的功耗,分析聚焦倍率以及冷却水流量对太阳能温差发电系统的净输出功率与净发电效率的影响.结果表明,存在最优的冷却水流量及最优的聚焦倍率,使得系统发电性能最大,最大净输出功率与净发电效率分别为15.86 W和5.61%;对温差发电器热端进行必要的保温,能够提高系统的发电性能.

Abstract:

A mathematical model of solar thermoelectric power generation was constructed in order to use the thermoelectric power generation technology that can directly convert solar energy into electricity. The influences of concentration ratio and cooling water flow rate on net capacity and net generation efficiency of system were analyzed by considering the power consumption of the cooling system. Results show that there exist an optimal cooling water flow rate and an optimal concentration ratio which can lead to the best electricity generation performance. The maximum net capacity and net generation efficiency are 15.86 W and 5.61%, respectively. The thermal insulation of the thermoelectric generator is necessary to improve the performance of system.
