背景技术Background technique
2016年9月1日中国政府公布了太阳能热发电示范项目标杆电价，其后公布了示范项目名单。示范项目大都集中在中国西北部，而这些地区的DNI均在2000或其以下，且临近北纬40度线，个别项目甚至超过该纬度，这在全世界已有的电站选址中是不曾有过的。在这些项目中包含了传统的槽式太阳能热发电技术，也包括塔式、菲涅尔式，还有自行发明的别具特色的聚光技术。从公开的信息获知所使用的槽式太阳能热发电技术均为30年前的传统技术，该技术至今没有大的突破，其构造复杂，硬件设备多，初始投资居高不下，如果不对其做重大技术改进，面对中国不太丰沛的光热资源很难实现政府规划和企业预期。为此必须对传统技术进行创新，使其适合中国特殊的自然地理环境，特别是通过减少硬件设备投资，提高热循环效率，最终实现降低初始投资和发电成本的目标。On September 1, 2016, the Chinese government announced the benchmark electricity price of solar thermal power generation demonstration projects, and then announced the list of demonstration projects. Most of the demonstration projects are concentrated in the northwestern part of China, and the DNI in these areas is 2000 or below, and close to the 40th parallel north latitude, and some projects even exceed this latitude, which has never been seen in the site selection of existing power stations in the world of. These projects include traditional trough solar thermal power generation technology, tower type, Fresnel type, and unique concentrating technology invented by ourselves. It is known from the public information that the trough solar thermal power generation technology used is the traditional technology 30 years ago. This technology has not made a major breakthrough so far. Its structure is complex, there are many hardware equipment, and the initial investment remains high. With technological improvement, it is difficult to realize government plans and business expectations in the face of China's not-so-abundant CSP resources. To this end, traditional technologies must be innovated to make them suitable for China's special natural and geographical environment, especially by reducing investment in hardware equipment, improving thermal cycle efficiency, and finally achieving the goal of reducing initial investment and power generation costs.
