长输管道建设的初始投资总费用可以划分为管道成本费用和压缩机成本费用,明确管道成本费用与管道内径的关系、压缩机成本费用与压缩机功率的关系后,通过建立数学模型对初始投资总费用进行优化。基于管道、压缩机、气源等的相关参数,运用PipePhase软件建立相应的数学模型,利用软件的优化功能对模型进行优化分析,得出两种优化结果,并对比分析二者的优劣,最终得出结论:在管道初始设计中考虑管道的后期操作费用,可以提高管道建设运营的总体效益。
The initial investment cost of long distance pipeline construction can be divided into pipeline cost and compressor cost. The relationship between pipeline cost and pipeline diameter is clarified. After the relationship between compressor cost and compressor power, the initial investment The total cost is optimized. Based on the relevant parameters of pipeline, compressor, gas source, etc., using the PipePhase software to establish the corresponding mathematical model, using the optimization function of the software to optimize the model to obtain two kinds of optimization results, and comparing the advantages and disadvantages of the two, finally It is concluded that considering the post-operation cost of the pipeline in the initial design of the pipeline can improve the overall benefit of pipeline construction and operation.
