This paper describes a method for estimating the position of a detected leak by applying a fluid transient model to a real-time pipeline system. The method takes account of flow rate and pressure profiles along a pipeline in a transient condition based on an assumption of quasi-steady-state flow. The result of casestudies using a hypothetical gas pipeline system shows that, even in a transient condition, the method gives a more accurate estimation of a leak position than conventional methods which do not consider flow rate or pressure profiles along a pipeline. The method is also applicable to a pipeline having consumer stations which cause abrupt changes of flow rate profile along the pipeline. Furthermore, the influence of instrument errors on the result of the method is discussed. The result also shows that the method is more accurate than the conventional methods.
