摘要：针对压气站运行能耗高的问题，基于动态规划算法，建立了以全线能耗最低为目标函数的管道运行优

化模型，充分考虑压缩机自耗气和性能劣化对管道流量的影响，采用深度学习算法拟合了压缩机的实际性能曲

线，形成了改进动态规划算法。实例验证结果表明，同一型号的压缩机会出现不同程度的性能劣化现象，采用

深度学习算法可有效改善压缩机性能曲线的预测精度，为后续管网优化提供基础；在考虑压缩机自耗气和性能

劣化后，开机数量由30台减少为24台，总功率由194.09MW减少为160.88MW，沿程压降由30.53MPa降

至23.21MPa，优化后燃气机组和电驱机组的平均效率均有大幅提升，减少了系统能耗，增加了管存量。
