摘　　要：在传统能源逐渐短缺、环境污染日益严重的情况下,“双碳”目标的提出具有重要的意义,可再生能源开发利用具有广阔的前景。现如今,利用有机工质作为循环介质是最常用的一种地热发电方式,通过清洁的有机工质进行换热不仅成本低,而且换热性能很强,能够很好的利用地下热水的热量。利用地热能设计的热电联供系统比传统发电系统节省占地面积小,同时此系统对环境保护有很大益处,与火力发电相比,使用地热资源发电能够很好的节省燃料同时减少CO_(2)、SO_(2)等废气的排放,对于推进实现“碳达峰”、“碳中和”具有重要意义。In the case of gradual shortage of traditional energy and increasingly serious environmental pollution,the proposal of the‘dual carbon’target is of great significance,and the development and utilization of renewable energy has broad prospects.Nowadays,the use of organic working medium as a circulating medium is the most commonly used geothermal power generation method.Heat transfer through clean organic working medium is not only low cost,but also has strong heat transfer performance,which can make good use of the heat of underground hot water.In budget and covers an area of land than the traditional power generation system.In terms of environment,this system is of great benefit to environmental protection.Compared with thermal power generation,the use of geothermal resources for power generation can save fuel and reduce emissions of CO_(2),SO_(2) and other exhaust gases,which is of great significance for promoting the realization of‘carbon emissions peak’and‘carbon neutrality’.
