Central control and computation: Run ladder diagrams/functional blocks/structured text programs to process logic control, interlocking, and regulation algorithms for power grids/generation equipment, ensuring real-time response.
I/O and Link Management: Manage up to 120 D20 I/O modules through D.20 Link HDLC, collect analog/digital data and issue control instructions, suitable for substation/power generation I/O intensive scenarios.
Multi protocol communication: serial port docking with RTU/PLC, Ethernet (optional) access to IEC 61850/Modbus/DNP3, meeting the needs of power dispatching and remote control.
Redundancy and Fault Tolerance: Supports redundant deployment of multiple CPUs, coupled with redundant power supply, improves system availability, and adapts to safety critical scenarios.
Fault diagnosis and logging: Real time monitoring of module/link/power status, recording error logs for quick location and recovery.
Grid side: The main controller of the substation automation VME chassis realizes telemetry/remote signaling/remote control and fault isolation, and interfaces with the dispatch system.
Power generation side: Control and data acquisition of synchronous generators/gas turbines, compatible with excitation/speed regulation system linkage, ensuring grid stability.
Industrial side: VME architecture control for large motors/process equipment, meeting the requirements of wide temperature/anti-interference and continuous operation.
