Abstract

The embodiment of the invention provides a method and device for performance evaluation of a natural gas pipeline network. The method includes abstracting a natural gas pipeline network into a pipeline network model represented by a directed weighted graph; adjusting the weight of at least one pipeline connection line in the pipeline network model to be zero according to a preset rule, and determining an optical gas supply flow direction strategy after the corresponding weights of the pipeline network model are adjusted; obtaining an optimal gas supply quantity allocation strategy of the pipeline network model under the corresponding optimal gas supply flow direction through a maximum flow algorithm; and determining the gas supply performance of the pipeline network model according to the optimal gas supply quantity allocation strategy of the pipeline network model under the corresponding optimal gas supply flow direction strategy. The method for performance evaluation of a natural gas pipeline network can comprehensively and effectively evaluate the performance of the natural gas pipeline network.

Description

technical field [0001] The present application relates to the technical field of performance evaluation of natural gas pipeline network, in particular to a method and device for performance evaluation of natural gas pipeline network. Background technique [0002] As a link connecting resources and markets, the safety of the gas supply capacity and the stability of the delivery capacity of the natural gas pipeline network are of paramount importance. The security of natural gas supply depends on the synergistic effect of "gas source - natural gas pipeline network - user". The stability of the transmission capacity of the natural gas pipeline network depends on whether the design of the system is reasonable and whether the operation of the system is optimal. Potential "air bottlenecks" in the system can have serious consequences, especially in the event of an unexpected event. [0003] However, accidents are often unavoidable due to environmental factors, human factors and o...
