On-line management, electric distribution automation, expert system, neural network.


By using advanced hardware and software technologies, the automation of the distribution electric network can be carried out in the next future. In the paper a reliable and flexible on-line management and control logic is described: it has been implemented step by step in the last few years. The decentralized control is carried out by the Programmable Logic Controllers (PLCs), which perform protection of the feeders, fault clearing, reconfiguration of the network and data acquisition, under the central control of an expert system, running on a personal Computer. The expert system performs monitoring of the system, network reconfiguration policy, overload forecasting and updating of the load diagrams of each feeder. The various functions have been carefully tested.
