摘要
低压管网和用户直接相连时,各用户的天然气用量是无法调节的,在发生事故情况下,各用户供气量的减少是不同的,其供气量的减少取决于支管压力降和用户支管与环网连接点的压力。对其水力可靠性进行准确分析计算,并提出了提高输配管网水力可靠性的途径。
Low pressure pipe network directly connect with the user,so the user can not adjust the consumption of natural gas.Different user has different gas decrease in accident.Gas decrease depend on pressure drop of branch and pressure between user branch and juncture of pipe network.We analysis and calculate the reliability of water conservancy.Then we give methods to improve the reliability of water conservancy in pipeline network.
