System and method for managing a power distribution system

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 the 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 powder 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.

A method 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 method comprising:

• receiving field measurement data that is measured by the distribution automation terminal devices at a same time;
• receiving an event signal generated from the distribution automation terminal devices;
• detecting a fault section of the power distribution system based on the received event signal;
• calculating protection coordination correction values of the protective devices for all independent systems of the power distribution system based on the received event signal;
• conducting real time system analysis using the field measurement data received from the DCP server;
• and
• transmitting control information including at least one among the protection coordination correction value, the fault section and system analysis information to the corresponding distribution automation terminal device.
