Substation telecontrol system is provided for automated monitoring and control of power supply modes and operation of substation electric equipment. The system has space-distributed data acquisition and control structure, and is deeply integrated with substation equipment. The system carries out recording of normal and emergency events, diagnostics of equipment state, communication channels, collection and transfer of data regarding power system state into higher-level systems.
Remote station of telecontrol system provides control and data acquisition from low-level equipment using digital discrete and analog signals, as well as via standard digital interfaces (Ethernet, RS-485). Remote station equipment is installed in remote control cabinet in substation signaling module on the basis of programmable logic controllers (PLC) with "hot backup" function produced by leading world manufacturers (B&R, Schneider Electric).
Remote station equipment includes operator's automated workstation for substation equipment operation control. Operator's automated workstation is based either on the basis of touch screen display as part of remote control cabinet, or on the basis of remotely located PC.
Functional capabilities:
Remote control cabinet is based on hot-swap-capable PLC, produced by well-known world manufacturers (B&R, Schneider Electric).
Remote control cabinet provides:
Design of remote control cabinet provides convenient external networks connection and control units replacement.
Substation control level allows monitoring of actual mode and status of substation main circuit from operator's workstation of operational personnel.
Functional features of operator's automated workstation:
Arrangement types of operator's automated workstation:
B&R hot-swap-capable PLC series X20CP3585 are installed into remote control cabinet and are applied for data acquisition and electrical equipment control.
