Power Distribution System

As the distribution automation system becomes more intelligent, countermeasures and preventive measures against various incidents on the complex lines are required.

Overview

The power facility automation system is divided into the EMS (Energy Management System), SCADA (Supervisory Control and Data Acquisition), and DAS (Distribution Automation System) depending on the facility that generates, transmits, and receives power.

Energy Management System (EMS) : A top level computer system that manages the entire electrical power system including power stations and substations acquiring information from the lower-level SCADA system
Supervisory Control and Data Acquisition (SCADA) : A computer system that manages transmission and transformation facilities, excluding the power plant
Distribution Automation System (DAS) : A technology that can actualize the automation of power system. A computer system is used to run the distribution system, such as remote monitoring and controlling power distribution facilities dispersed in a wide area at the distribution command center, detecting defective line sectors, and switching to optimal system in case of an incident occurrence

Power-EYE Distribution Automation System

The Power EYE system is a system for distribution automation and can shorten the blackout sector and failure/blackout time by remotely monitoring and controlling power facilities installed in the distribution system and distributed power sources, ranging from substations to customers, as well as acquiring and monitoring the field information (current, voltage, status information, failure status, etc.) of the distribution facility in real time, and controlling the facility remotely.

Solution

Operation Program (HMI)

An operator program that receives and displays the status information of the field facility for monitoring, control, and remote setting, in order to control the statuses of the terminal devices. This program can check the blackout sector in real time by monitoring and controlling the Feeder Remote Terminal Unit (FRTU) in the distribution center, which is distributed in remote places, and also by collecting line operation information such as current and voltage.

FEP Program

FEP stands for Front End Processor. The FEP program collects information suitable for the characteristics of each device using power system field devices, and various communication methods and protocols, and delivers the necessary commands to each device according to the operator’s command. It is located in front of the central control unit and collects and processes data at high speeds from lower-level terminal devices and delivers the results to the server to prevent communication bottlenecks and to improve overall system performance.
