高压直流阀冷系统漏水检测功能的改进（Improvement of Leakage Detection in Valve Cooling System for HVDC Transmission Systems）
高压直流输电 阀冷系统 漏水检测
2010/8/17
分析了南方电网中3回高压直流输电系统中的阀冷系统漏水检测与保护功能，发现均存在一定设计漏洞，装置有可能因此出现误动和拒动，建议在天广直流系统以及高肇直流系统的阀冷控制系统中增加判据，使之功能更完善。
基于Exergy研究的地源热泵降温系统性能分析（Performance Analysis on Ground Source Heat Pump Cooling System Based on Exergy Research）
地源热泵 降温 可用能
2009/5/22
以地下水式地源热泵系统在农业温室和办公楼中的夏季降温研究为例，归纳出地源热泵降温系统的能量利用质量模型——Exergy分析模型，以Exergy损失Edest和Exergy效率ε为评价指标对降温工况下系统及其组成单元的热力学性能进行分析和探讨。分析结果表明：蒸发器的Exergy效率达到92.5%，具有较高的能源利用质量；冷凝器的Exergy效率相对较小，Exergy损失较大，不可逆性大；总体来看，系...
