摘　　要：提出一种改进型的槽式聚光电热联供系统,该系统在电热联供系统的基础上增加一个金属腔体再热级,实现输出高品质电能的同时输出较高温位的热能。构建改进型槽式聚光电热联供系统实验装置,通过测试实验,发现改进型系统的电输出性能和热输出性能均有所提高。分析改进型槽式聚光电热联供系统与单晶硅平板光伏系统、太阳能热水系统三者之间的经济效益,结果表明,改进型系统的经济性能高于单晶硅平板光伏系统,低于太阳能热水系统。An improved combined heat and power supply system based on solar trough concentration system was put forward. A metal chamber was added as further heat stage for the combined heat and power supply of solar trough concentration system, the solar cell＇ s performance was optimized and high temperature thermal energy output was achieved at the same time. The experimental results demonstrate that the electric output performance and heat output performance of the modified system are improved. Analysis of the economic benefit of the modified system, the mono- crystalline silicon flat-plate PV system and the solar hot water system show that the economic performance of this modified system is higher than the mono-crystalline silicon flat-plate PV system, lower than the solar hot water system.
