A Distributed Architecture for Power Network Fault Analysis

This paper discusses a distributed diagnostic algorithm for fault analysis in power networks. DAPoN is a model-based diagnostic algorithm that incorporates a hierarchical power network representation and model. The architecture is based on substation-server implementation. The structural model is a six-level representation with each level depicting a more complex network of components than the previous one in the hierarchy. Each level is modeled by the object-oriented representation. The distributed functional representation is also done in six levels where each level contains the behavioral knowledge related to components of that level in the structural model. The diagnostic algorithm of DAPoN is designed to perform fault analysis in pre-diagnostic and diagnostic levels.
