Distribution Automation Monitoring Using Petri Net

The growth of the electricity distribution networks and increasing use of distributed generators in the networks, lead to complexity of monitoring of automation process and increase the possibility of wrong decisions in operation of these networks. Hence, a system that can be housed in energy control centers to assist distribution network operators in cases of failures diagnosis is necessary. Regarding this issue, this study employs Petri net modeling to provide a model of automation system on a distribution network that can be implemented in the monitoring system of distribution networks control centers, and using the information received at these centers, to monitor the various stages of automation process, detect faulted sections, and also, to inform the operator about the incorrect states in a real time manner. Therefore, the proposed model, informing the operator and assisting him to decide correctly, cause to reduce incorrect outages and increase reliability of distribution networks.
