- Abstract:
- The problem of locate disturbance sources in power network is a critical task. Several methods based on multi point measurement techniques have been proposed in the last few years proving a good contribution on this filed. In this paper an event-based distributed measurement system for power network has been developed. The system adopts a hierarchical approach to monitor the power network: the sensing parts are measurement systems which perform the monitoring of Power Quality (PQ) parameters such as Total Harmonic Distortion (THD) and Root Mean Square (RMS); the management part is a supervisor node which uses an asynchronous symmetric communication protocol to exchange information with the devices connected to the network. When an abnormal behaviour has recorded, the measurement system notifies the supervisor node which begins to download the data from every smart sensor connected to it. To give much more freedom end flexibility to the sensors network, the smart sensors use the Web services technology to export its services and functionalities. In this paper, the main parts of the system are explained in details and some experimental results are reported.
