|---|---|
| SAS station | · Collects field information through communication with CSD using TCP/IP protocol
· Data acquisition and processing in real time for all substation facilities such as GIS, IEDs, TR, Security equipment, and others · Executes automatic control functions such as accident recognition, auto transfer, and power factor control in all substation facilities · Analyzes accident type and operational conditions through the operating curve data of the IEDs |
| CSD (Communication Server Device) |
· Provides operational information on the power equipment to the upper energy management system that controls the power supply and distribution line
· Controls the power equipment by the order of energy management system · The communication control device is applied to the substation to acquire, analyze and process the system operation data |
| RTU | · Acquires the operation information of security equipment and others not equipped with IED and transmits it in CSD · The message transmitted via CSD is analyzed in order to perform the command and the result is returned in this device |
| Protective Relay Board |
· Accommodates the IEDs for the protection of GIS, TR, and others in order to communicate through CSD at high-speed · Applies Intelligent Electronic Devices (IEDs) equipped with a communication function |
