| 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 Control 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 | By accommodating the IEDs for the protection of GIS, TR, and others in order to communicate through CSD at high-speed Applies digital integrated relay (IED) equipped with a communication function |
| Operation support | System operation screen, acquired information display, operator/engineer support, system operation status monitoring |
|---|---|
| Automatic control | Automatic interlocking, synchro-check, balanced voltage regulation (Tap-changer control), transformer load balance control Automatic power failure / return control, load shedding, automatic re-closing function, power factor control |
| Facility protection | Generator protection, bus protection, bay protection, transformer protection, power line protection, motor protection |
| Data acquisition and application | Remote data acquisition and decision, event alarm report record, accident wavefome capture |
| Data Link | Support of various communication protocols |
| Facility status monitoring | GIS gal malfunction condition, circuit breaker condition, transformer condition |
