一种具有自定义功能的管网系统性能仿真平台初探

Study on Pipenet System Performance Simulation Platform with Custom Function

管网系统在能源、化工、冶金等行业都有着广泛的应用,而其性能仿真研究却面临着通用性和专业性矛盾的问题,因此,文章提出了以Matlab/Simulink工具为平台来解决矛盾的思路。借助于Matlab/Simulink可以自定义能够满足特殊需求的专业元器件模型库,并搭建不同的系统模型,最后再借助于循环求解器进行求解。作为这种思路的初步探索,文章首先设计了两类单管路仿真模型,介绍了串、并、混联管路仿真模型的搭建方法,选取了文献中的两个复杂管网系统作为算例,对其进行了建模与求解,结果证明采用该思路进行管网系统性能仿真研究的可行性与正确性。该研究为今后建立具有通用性和灵活性、并同时能适应各种专业特殊需求的自定义功能的仿真平台打下基础。

Pipenet system has a wide range of applications in energy,chemical,metallurgical and other industries,but its performance simulation study is facing with a dilemma about the versatility and professiona-lity.Therefore,this paper presents a new idea to resolve this conflict by taking the Matlab / Simulink as a tool,and conducts a preliminary exploration.The professional component model library can be customized to meet the special needs by means of Matlab / Simulink,and different system models can be built and finally solved with loop solver.As a preliminary exploration of this idea,this paper designs two single-line simulation models and introduces the method to build series,parallel and series-parallel simulation models first.Then,two complex pipenet systems are selected from other papers to be modeled and simulated as the computation examples.Results show the feasibility and correctness of the idea,and lay the foundation for the future simulation platform,which should have the features of versatility and flexibility as well as the custom function being adapted to the special professional needs.
