数字孪生智慧燃气系统:概念、架构与应用

Digital twin-based smart gas system:Concepts,architecture and applications

燃气作为重要的能源之一,在生活与生产中发挥着重要作用。首先,调研分析了燃气运营呈现出的自动化、精准化、便捷化等发展趋势,并指出当前面临的数据获取不全面、信息系统不兼容、运营操作不精确、用户服务不便捷等挑战。在此基础上,将数字孪生技术与燃气供给侧、输配侧和需求侧的关键场景、关键对象、关键服务紧密结合,提出了数字孪生智慧燃气系统,从物理实体、虚拟模型、数据中心、信息系统及应用服务等5个方面阐述其体系架构和共性关键技术,并探讨分析了数字孪生智慧燃气系统中管网设计、完整性管理、巡检、应急、输配调度及用户服务的解决方案。详细分析了提出的数字孪生智慧燃气系统在燃气企业中的应用实践,以期为智慧燃气的发展与建设提供参考。

As one of the important energy sources,gas plays an important role in production and life.The development trends in gas industry were investigated and analyzed,such as automation,precision and convenience.At the same time,the challenges such as incomplete data acquisition,incompatibility of information systems,inaccurate operations,and inconvenient user services were pointed out.Based on the investigation and analysis,a digital twinbased smart gas system was proposed,which tightly integrated with digital twin technology in key scenarios,key objects and key services of the gas supply side,the transmission and distribution side and the demand side.The architecture and common key technologies of this system were explained from the physical entity,virtual model,data center,information systems and application service.Furthermore,six types of service solutions in the system were discussed and analyzed,including pipe network design,integrity management,inspection,emergency response,transmission and distribution scheduling and user service.The application practice of the proposed system solution in some gas companies was explained in detail to provide a reference for the development and construction of smart gas.
