摘要
针对复杂输气管网中热物性和水力工况变化，提出了带沿线温度变化的四方程静态仿真模型，并采用四阶龙格—库塔法进行数值求解。其结果可用于静态条件下复杂输气管的调度和分析，同时为在线设备如压缩机站的模拟和动态仿真提供了依据。
In the light of thermal physical properties and hydoraulic condition variation,the phandom model of the static state of the quadratic equition with linear temperature variation is presented,and the four-step Ronge-Kutta method is used to get the numerical value solution.This result can be utilized to dispatch and analyze complicated gas transmission pipelines under the static condition, at the same time, it also provides the base for simulation and kinitic phandom of on-line equipments, such as the comppressors station.
