Application of domestic cloud simulation software CloudLPS for liquid pipelines

国产化液体管道云仿真软件CloudLPS(Cloud-based Liquid Pipeline Simulator)是一款具备自主知识产权的液体管道通用仿真软件,在此介绍其应用。首先通过一个案例,介绍了从管网模型搭建、仿真计算到结果查看的操作流程;然后采用CloudLPS软件对稳态输送、瞬态水击、冷热油交替输送等多种不同工况进行计算,并将计算结果与国外商业软件SPS、TLNET进行对比,发现CloudLPS的水力和热力仿真精度与SPS、TLNET相当;随后将CloudLPS应用于常温输送、加热输送、冷热油交替输送等实际管道问题,并与现场数据进行了对比,发现CloudLPS能满足实际工程计算的需求;最后展示了软件可视化控制逻辑搭建与能耗优化两大特色功能。结果表明:CloudLPS具有强大的水热力仿真、逻辑控制以及能耗优化能力。

The Cloud-based Liquid Pipeline Simulator(CloudLPS)is a universal liquid pipeline simulation software with completely independent intellectual property rights in China.Herein,its applications are introduced.Its operation processes from pipeline network modeling and simulation calculation to result viewing are elaborated based on a specific case.Then,calculations are performed with CloudLPS for various operating conditions,including steady-state transportation,transient water hammer,and alternating transportation of cold and hot oil,after which the results are compared with those obtained from the foreign commercial software SPS and TLNET,making the discovery that the CloudLPS has comparable accuracy in terms of hydrodynamic and thermal simulations.Subsequently,CloudLPS is applied to solve practical pipeline problems such as normal-temperature transportation,heated transportation,and alternating transportation of cold and hot oil.By comparing the results of these practical applications with the field data,it is proven that the CloudLPS can meet the requirements of the actual engineering calculations.Finally,the two special features of CloudLPS,including visual control logic construction and energy consumption optimization,are presented.The results of this paper indicate that CloudLPS is of great competence in hydrodynamic and thermal simulations,logic control,and energy consumption optimization.(22 Figures,8 Tables,35 References)
