Data Acquisition | Collects real-time data from the station-side acquisition system to implement basic "four telemetry" (telemetry, telesignaling, telecontrol, teleadjustment) functions. |
Data Processing | Includes functions such as data rationality checks, analog value processing, status value processing, alarm value processing, cumulative value processing, and calculated quantity processing. |
Human-Machine Interface (HMI) Function | Provides a fully graphical distributed HMI developed based on cross-platform Qt, supports full mouse and shortcut key operations, and can display high-quality 3D graphics. |
Graphical Editing Function | Enables online generation, editing, and modification of 10kV distribution network diagrams and overhead network diagrams, etc., and provides rich dynamic data forms and graphic element editing functions. |
Event and Accident Alarm Processing | Handles power equipment status changes, value limit violations, equipment failures, channel failures, operation events, and user-defined alarms. |
Sequence of Events (SOE) Recording | Records the action sequence of major switch signals with millisecond-level precision to form an action sequence table, supporting various query and printing methods. |
Historical Snapshot Recall and Post-Event Analysis (PDR) | Allows recalling the system state at any moment based on historical data storage points, and can trigger the recording of pre/post-accident data via predefined events to support accident replay. |
Security Subsystem | Provides a multi-level hierarchical security management mechanism, strictly controls personnel, machines, and operation permissions, and records important operations. |
Fault-Tolerance Measures | Provides various fault-tolerance measures, such as communication timeout handling, checksum error handling, remote control lock/unlock, remote control secondary confirmation, and illegal value handling. |
Printing Output | Supports scheduled and on-demand printing of reports, real-time printing of events and alarms, as well as graphic printing such as wiring diagrams and curve graphs. |
System Time Synchronization | Can use GPS to provide standard time, sends time synchronization commands to the entire system (including master station nodes, RTUs, FTUs, etc.), and supports manual time setting. |
Equipment Management Function | Graphically displays the real-time operation status of the system, configuration and status of each node and device, network load, etc., and provides online system maintenance functions. |
Station-Side System Maintenance | Supports remote maintenance of substations and terminals from the master station via communication channels, or local maintenance using a laptop, with functions including parameter setting and system diagnosis. |
Feeder Automation (FA) | Implements detection, location, isolation, and restoration of feeder faults, divided into three layers: terminal-based detection, substation area control, and master station global coordination. |
Open System Interface | Enables data exchange and flexible interfacing with higher-level SCADA, MIS, load control systems, and electricity business management systems, etc. |
