1. A method for detecting and locating leaks in a pipeline network in real-time, comprising the steps of:

  • providing a flow model that characterizes flow behavior for at least one of steady and unsteady states respectively corresponding to an absence and a presence of model leaks in the pipeline network, the flow model including a leaking factor kL;

    providing a deterministic model to evaluate at least one of a leak status and a no leak status relating to the pipeline network using deterministic criteria, the deterministic criteria being based on a Liapunov Stability Theory; and

    constructing a deviation matrix based on the flow model and the deterministic model to generate eigenvalues, and generating a leak alarm when at least one of the eigenvalues is less than a predetermined value.
