摘要
The present invention provides a method and apparatus for determining pipeline-flow status parameters of natural-gas-pipeline network, the method includes: dividing natural-gas-pipeline network into multiple areas according to its topology structure; for each area, establishing first control equation representing operating status in pipelines of the area, of which unknown parameters are pipeline-flow status parameters in the pipelines of the area, known parameters include structural parameters of pipelines, operating parameters of components and physical-property parameters of natural gas; for each area, establishing second control equation representing operating status at boundary nodes of the area; solving the first and second control equation to determine the pipeline-flow status parameters in the pipelines and at the boundary nodes of each area. In the present invention, algebraic equation set with fewer equations is solved, thereby achieving high efficient and rapid calculation of the pipeline-flow status parameters of the natural-gas-pipeline network, which is easy to operate.
