DIGITAL SUBSTATION AUTOMATION SOLUTIONS – ONE-STOP INTEGRATION

• The GWPC400-CMC Station Common Measurement and Control Panel is designed for station-wide common signal acquisition, busbar voltage supervision, equipment status monitoring and remote control in substations, power plants and renewable energy facilities.
• Built around the GWPR400-CMC Common Measurement and Control Unit, the panel serves as an interface between primary equipment, station auxiliary systems and the substation automation system or SCADA platform. It collects analogue measurements, binary status signals and alarm indications while providing supervised control and remote regulation functions for designated station equipment.
• The GWPC400-CMC is suitable for both conventional and digital substation applications. It can be configured for projects at voltage levels such as 132 kV, 66 kV and 33 kV, as well as other voltage levels subject to project requirements.

• The GWPC-DFR Digital Fault Recorder Panel is designed for power plants, substations, renewable energy facilities, and industrial power systems. It continuously monitors and records electrical quantities, equipment status signals, and protection events before, during, and after power system faults and disturbances.
• By integrating transient fault recording, continuous disturbance recording, sequence-of-events recording, fault analysis, and time synchronisation, the GWPC-DFR provides reliable data for reconstructing the chronology of disturbance events, analysing protection performance, locating faults, and evaluating the dynamic and operational performance of the power system.
• The GWPC-DFR is primarily a monitoring, recording, and analysis system. It does not replace protection relays and is not normally used to issue protection trip commands.

• The GWSC-SUB Substation SCADA System is designed for international power projects and fully complies with IEC standards. It supports 132kV, 110kV, 66kV, 33kV, 22kV and 11kV substations, suitable for both new installations and substation modernization projects, enabling unattended or minimally attended operation.
• The system provides complete Four-Remote functions (remote measurement, signalling, control and adjustment), with optional video surveillance integration. Key functions include SOE recording, fault playback, disturbance analysis, alarm management and operation reporting. Integrated with the GWPC-FPS Five-Protection System, it supports IEC 61850 interlocking logic and seamless integration of equipment monitoring, environmental monitoring, security and fire-alarm systems.
• A four-tier architecture (station control, communication, bay and process levels) ensures reliable and independent operation. Bay-level devices maintain protection, control and tripping functions even during communication failures.

The GWPC-RTU RTU Communication Panel is primarily used in photovoltaic power plants, substations, distribution systems, power generation facilities, and other power automation applications for communication protocol conversion and data transmission between intelligent electronic devices (IEDs) and supervisory control systems.

Main Functions
Protocol Conversion;Supports protocol conversion and interoperability among various communication protocols, including:

• Modbus/IEC 60870-5-103/IEC 60870-5-104/TCP-IP/DNP3/IEC 61850

Data Transmission and Monitoring

• Data Upload: Telemetry, status indications, alarms, and event information are transmitted in real time to centralized control centers, SCADA systems, or utility dispatching centers through fiber-optic networks, dedicated communication networks, or wireless communication channels.
• Remote Monitoring and Control:Supports remote monitoring, supervisory control, and operational management of plant and substation equipment from dispatching centers, ensuring the safe and reliable operation of the power system.
