System and method for managing a power distribution system

摘要

Disclosed herein is a system and method for managing a power distribution system in which has an improved system protection and fault section determination structure in consideration of distributed power supplies, has an improved server and communication structure for one-to-one synchronization measurement, and conducts real time system management and control. The system for managing the power distribution system uses field measurement data and an event signal to detect a protection coordination correction value of a protective device for protection of the system and a fault section of the power distribution system, performs real time system analysis using the field measurement data, and transmits control information including at least one of the protection coordination correction value, the fault section and the system analysis information to a DCP server.

主权项

1. A system for managing a power distribution system, the power distribution system comprising a plurality of protective devices provided on lines between a substation, a transformer and a load, and a plurality of distribution automation terminal devices installed in the respective protective devices, the system comprising:
an SOTS terminal collecting field measurement data measured by the distribution automation terminal devices at a same time, and an event signal generated from the distribution automation terminal devices; a DCP server receiving the field measurement data and the event signal from the SOTS terminal, receiving a control command for the distribution automation terminal devices, and transmitting the control command to corresponding distribution automation terminal devices; a main server detecting protection coordination correction values of the protective devices for system protection and detecting a fault section of the power distribution system based on the event signal received from the DCP server, the main server conducting a real time system analysis using the field measurement data, and transmitting control information including at least one among the detected protection coordination correction values, the fault section and the system analysis information to the DCP server; and a database storing and managing at least one among the field measurement data, the event signal, the protection coordination correction values, the fault section and the system analysis information that are received from the main server.
