SCADA (Supervisory Control and Data Acquisition System) fulfills the role of monitoring and controlling the power facility located on the distance site in on-line, which is based on the information about circuit breaker status, analog and digital data collected by the RTU (Remote Terminal Unit) and transmitted to the central computer through the line or wireless communication network.
| Master | Execute basic functions of the SCADA System Execute shared DB management, real time data acquisition and processing, automatic control, demand control, power factor control, emergency power generation control Alarm event processing and system service function |
|---|---|
| Dispatcher | Uses information from the master to support the operator and to supervise the power facility Supports the dispatcher screen display, alarm indication, report generation function, etc. |
| SMC | Manages the large capacity Database in real time using Oracle DB management software. Analyzes and displays the past trend data in real time |
| FEP | Communicates with field devices such as RTU for data acquisition based on real time OS Collects various events arising from the site in real time and transmits them to Master Command control from Master for transmission to field devices such as RTU |
| RTU | Collects information from the field device and executes data processing, monitoring and control function Transmits collected real data to the central computer through the line or wireless communication network |
| Remote monitoring | Circuit breaker-Relay operation status, collection of SOE information |
|---|---|
| Remote control | CB control, multi-step control, demand control, power factor control, emergency power generation control |
| Remote measurement | Instant data like voltage and current, accumulated data like WH, acquisition of measurement value through the communication with IED |
| DB management | DB generation and modification, daily/monthly/yearly report generation, alarm history management, trend display |
