Abstract

This thesis deals with fault detection and isolation in water distribution networks. Inflows of contaminated water in water distribution networks are regarded as faults. The contaminant concentration in a water distribution network can be modelled by a linear time-invariant system, where the input of the system represents inflows of contaminated water, and the output corresponds to sensor measurements. We consider fault detection and isolation by residual generation. This thesis provides a necessary and sufficient condition for the existence of a bank of residual generators that induces a diagonal transfer matrix from faults to residuals. Furthermore, we present a graph theoretic characterization of this condition. This characterization allows us to verify the existence of a bank of residual generators in a more intuitive way, namely by analyzing the structure of the water distribution network under consideration.
