Unbounded system model allows robust communication infrastructure for power quality measurement and control

A robust information infrastructure is required to collect power quality measurements and to execute corrective actions. It is based on a software architecture, designed at middleware level, that makes use of Internet protocols for communication over different media. While the middleware detects the anomalies in the communication and computation system and reacts appropriately, the application functionality is maintained through system reconfiguration or graceful degradation. Such anomalies may come from dynamic changes in the topology of the underlying communication system, or the enabling/disabling of processing nodes on the network. The added value of this approach comes from the flexibility to deal with a dynamic environment based on an unbounded system model. The paper illustrates this approach in a power quality measurement and control system with compensation based on active filters.
