地热能及与其他新能源联合发电综述

我国地热资源丰富，且分布范围广。随着能源短缺和环境恶化问题的出现，地热能作为一种可再生的清洁能源受到人们的广泛关注，并将其用于发电领域，以降低污染物的排放、减缓煤炭等化石燃料引发的温室效应，实现能源结构的优化。介绍了地热蒸汽发电技术、地热水发电技术、干热岩发电技术、岩浆发电技术等地热发电技术的工作原理，并在适用范围、发电效率、发电成本、优缺点等方面对其进行比较。同时，阐述了地热与太阳能、生物质联合发电技术；分析了地热发电技术中存在的问题，以期为地热能在我国乃至世界范围的实际应用提供参考。

Overview of Geothermal Power Generation and Joint Power Generation With Other New Energy Sources

Geothermal resources are abundant and widely distributed in China. With the emergence of energy shortage and environmental deterioration, geothermal energy, as a renewable and clean energy source, has been widely focused and used in power generation to reduce the emission of pollutants, mitigate the greenhouse effect caused by fossil fuels such as coal and realize the optimization of energy structure. This paper introduced the working principle of geothermal steam power generation technology, geothermal hydropower generation technology, dry heat rock power generation technology and magma power generation technology, and compared them in terms of scope of application, power generation efficiency, power generation cost, advantages and disadvantages, etc. In addition, joint power generation technology with solar power and biomass power was suggested, the problems of geothermal power generation were points out, in order to provide a theoretical basis for the practical application of geothermal energy in China and even in the world.
