为了进一步研究多热源多环集中供热管网水力特性,基于流体网络分析法,针对公共管道上是否存在用户,以及存在用户时是否存在水力交汇用户的不同情况,提出公共管道断开省略、两端点设置虚拟用户或虚拟热源等相应的建模方法。通过已搭建的多热源多环供热管网实验台,分别对3种不同工况单热源双环、双热源双环变工况、三热源三环理想工况进行建模仿真和实验研究,并在考虑仪表测量误差的基础上进行误差分析。结果发现,在3种工况下,仿真数据与实验数据的相对误差绝对值的最大值分别为1.96%、3.60%和1.00%,验证了该仿真模型的有效性和准确性,进而证明了建模方法的合理性和适用性。
In order to further study the hydraulic characteristics of a multi-heat source multi-ring central heating pipe network, based on the fluid network analysis method, aiming at the existence of users on the public pipelines and the existence of users in different situations, Endpoints Set the appropriate modeling methods for virtual users or virtual heat sources. Through the built multi-heat source multi-ring heating pipe network experimental platform, three kinds of working conditions of single-mode double-ring, double-source dual-ring variable working conditions and three-heat source three-ring ideal working conditions were simulated, Error analysis based on the measurement error of the instrument. The results show that under the three conditions, the maximum absolute value of relative error of simulation data and experimental data is 1.96%, 3.60% and 1.00% respectively. The validity and accuracy of the simulation model are verified, The rationality and applicability of the modular method.
