Taking a high-pressure gas pipeline network of dual gas sources and dual power plant users as the research object,the pipeline network model is built by using Pipeline Studio software,and the pipeline network under the condition of small hole leakage is simulated.The maximum allowable leakage aperture is determined,the influence of leakage location on the flow rate of power plant users and the reliability of user gas supply is analyzed,and the pipe sections that re-quire special attention are identified.Compared with branch pipe users,the main pipe users have stronger self-adjustment ability under the condition of small hole leakage,and the flow rate can reach stability faster.For branch users,it should pay special attention to and prevent leaks in the pipe section where the branch pipe users are located.For main pipe users,both branch and main pipes are key focus areas.
