Pipe network system dynamic and online simulation modeling method for parallel computing

Abstract

A pipe network system dynamic and online simulation modeling method for parallel computing comprises the steps: establishing simulation models for a station yard, connection points outside the stationyard and pipelines in a pipe network system respectively, so that the station yard and the pipelines as well as the pipelines are connected through the connection points. The method particularly includes: firstly establishing a connection point dynamic simulation model and a station yard dynamic simulation model; secondly, performing spatial discretization on all the pipelines to obtain uniformlydistributed internal nodes of the pipelines; establishing a left line, a right line and a thermal line for each node to obtain a pipeline dynamic simulation model; and finally, connecting the simulation models through the connecting points, calculating the station yard, the connection points and the pipeline in parallel by means of the simulation models until the simulation is finished. Accordingto the method, the station yard and the connection points are analyzed in parallel at the same time, then the pipelines are analyzed in parallel, the method can be used for multi-thread, multi-process and GPU technologies and even computer clusters to achieve parallel computing, computing and hardware resources are fully utilized, and the analogue simulation computing speed is increased.
