新一代节能供热网络的立体拓扑结构建模
Three-dimensional topology structural modeling for a new generation district heating network
摘要：
随着绿色建筑技术的推广，在新一代区域供热网络中包含热电联产、废热利用、可再生能源和储热等节能环节。除了不断开发和推广供给侧和需求侧的节能技术外，连接供需双方的热网也需要进行技术改进。比较了多种拓扑结构对供热质量的影响，发现基于平面拓扑结构的传统网络分析方法很难解决加入各类节能环节后出现的输配问题，因此提出了一种改进的立体网络建模方法。该方法无需基于图论搜索基本回路，且能够在三维非规则拓扑结构上直接对热网进行水力和热力工况分析。给出了该方法的详细建模过程，并与传统方法进行了比较。
Abstract：
With the development of green building, the new generation district heating network includes many energy efficiency measures, such as CHP, waste heat utilization, renewable energy and thermal storage, etc.In addition to continually develop and promote energy efficiency technologies in the supply and demand sides, the district heating network linking with the both sides needs technical improvement. Compares the influences of some topology structures on heating effect, and finds that the traditional modeling method based on flat topology network is very difficult to resolve the distribution problem with multiple energy efficiency measures. Therefore, proposes an improved method based on three-dimensional irregular topology structure. Without basic circuit based on graph search, directly analyses the hydraulic and thermal condition of heating network based on the three-dimensional irregular topology structure. Presents the modeling process of this method in detail and compares it with the traditional ones.
