Optimal selection method and device based on multiple natural gas long-distance pipeline design schemes

Abstract

The invention provides an optimal selection method and device based on multiple natural gas long-distance pipeline design schemes. The optimal selection method comprises the following steps: determining the economical cost of pipelines according to the pipeline construction period cost and the pipeline operation period cost; determining the safety cost of the pipeline according to economic loss, personnel health loss, environment loss and reputation loss caused by the accident of the pipeline; determining the reliability cost of the pipeline according to the pipeline transportation income loss of the pipeline and the contract compensation cost; and determining a pipeline design scheme in the plurality of natural gas long-distance pipeline design schemes according to the economical cost, the safety cost and the reliability cost by utilizing a machine learning algorithm. According to the method, the defect that only economy is considered in comparison and selection of an existing natural gas long-distance pipeline design scheme is overcome, factors and indexes such as economy, safety and system reliability are comprehensively considered, and a more comprehensive natural gas long-distance pipeline engineering design scheme comprehensive evaluation system and a comprehensive index calculation method are provided.

Description

Technical field [0001] The present invention relates to the field of natural gas pipeline transportation techniques, and more particularly to a preferred method and apparatus based on a plurality of natural gas long conduit design. Background technique [0002] With the progress of the energy revolution, especially in carbon neutralization, natural gas is an important bridge of high pollution fossil energy to new energy conversion, and its demand presents high-speed growth trends. At the same time, the proportion of natural gas in my country has increased year by year. As an important bond that connects upstream resources and downstream markets, natural gas longport pipeline is the only choice for massive delivery of natural gas. The construction of natural gas long-transport pipeline is a huge systematic engineering. If natural gas long delivery is achieved in the expected economic benefits in the expected design life, the design plan will be reasonably selected for its design. ...
