TECHNOLOGY OF INTELLIGENT DISTRIBUTION TERMINAL WITH THE ABILITY OF UPDATING DISTRIBUTION CIRCUIT TOPOLOGY

摘要

With the increasing requirement of the self-adaptation topology change of distribution line, not only should FA realize distribution automation terminal plug and play, but also be able to adapt to changes in the topology of distribution lines. Distribution circuit topology model can reflect the connection of primary equipment and the parameters of distribution operation, which plays a very important role in the safe and stable operation of the distribution network. In the actual operation of the distribution network, in addition to changes in the topology caused by a device, distribution line load transfer, fault isolation, non fault area to restore power supply will also cause topology changes. Therefore, the static topology model and dynamic topology model of distribution lines are introduced as the basis for the realization of the topology adaptation of distribution lines.
