- 摘要:
- 介绍了涩宁兰管输系统的构成，采用SPS软件对管输系统的两种主要失效工况进行了详细的模拟和分析。模拟结果显示，当压气站失效时，越靠近末站的压气站对管输系统的影响越大也越快，同时适当提高正常工况下末站的供气压力，可提高管输系统的可靠性；当单管失效时，越靠近末站的单管失效对管输系统的影响越大也越快。因此在日后的管道运行维护中，需分清主次，对重点段管道进行重点巡视和维护，以确保整个管输的安全平稳运行。
Introduced is the structure of the Sebei-Ningxia-Lanzhou gas pipeline system，simulated and analyzed are two kinds of main failure working conditions of the system by using the SPS software and simulation results show that failure of the gas compressor stations closer to the terminal station has larger and faster effect on the system and reliability of the system will be improved if gas supply pressure of the terminal station is increased properly in normal working condition. Also，failure of the single pipelines closer to the terminal station has larger and faster effect on the system. Therefore，special patrol and maintenance shall be conducted to those important sections in order to ensure that the whole gas pipeline system operates safely and smoothly.
