The paper makes an analysis of the heating load of solar energy in buildings in Yushu district with De ST software. The results show that the modified architecture has remarkable energy saving effect,energy-saving rate being 24%,27% and 31% respectively when room temperature is at 18 ℃,16 ℃,and14 ℃. Meanwhile,with Poly Sun software,the paper analyzes the energy saving of the solar heating system including the solar collector performance,system scale,installing angle,water tank volume,geographical position,geographical location,etc. The results of the analysis provide technical support for the popularization of solar heating system.

本课题立足于青海省内已建设的离网光伏电站的实地调查情况,从太阳能资源分布、离网光伏电站的建设方案、运行维护和涉及安全、监测技术等方面,对已建电站运行维护过程中存在的主要问题及原因进行了梳理和分析,并通过典型实例提出新建电站在设计技术和运行维护中优化和改进方案,为利用分布式光伏电站有效解决青海省广大农牧区部分用电问题提供有益尝试.

文章对青海省9个县区在建和已建的25座大中型沼气工程的运行情况进行全面调研,分析沼气工程建设在地质条件、高寒气候等方面存在的特殊性,对存在的问题进行分类梳理,总结出沼气工程在设计、建设和运行中存在的技术瓶颈和制约因素,并针对这些技术瓶颈给出建议.
