Abstract: The primary goal of this research is to improve the accuracy of leak detection and the precision of leakage position location based on transient simulation. First, the principle of applying transient simulation to detect pipeline leakage is presented, as well as its characteristic and limitation are analysed. Second, the paper analyses the influence of leakage quantity and leakage position on gas flow parameters to determine which parameter is more appropriate to enhance the accuracy of leakage detection. Third, high-precision mathematical model and numerical solution method are adopted to improve the precision of leakage position location, and finally an example is taken to demonstrate the feasibility of this method for gas pipeline leakage detection and location.
