3. Structure and Composition
Main Control Unit (Controller)
Responsible for core logic processing, communication protocol stacks (MMS/GOOSE/SV), and human-computer interaction.
Power Supply Module
Provides multiple outputs such as 48 VDC/24 VDC/12 VDC, supporting dual-power input grid connection or switching.
Communication Interface Module
Includes Ethernet switch (supports VLAN, QoS), fiber optic transceiver, serial port card, and USB/RS‑485 converter.
Protection & Measurement IED
Integrates Current Transformer (CT)/Voltage Transformer (VT) interfaces, supporting multiple analog inputs (temperature, pressure, oil level, etc.).
Logic & Control IED
An execution unit that implements automation logic (such as automatic reclosing, load switching, fault location).
Optional Expansion Modules
Such as Hardware Security Module (HSM), additional Digital Input/Output (DI/DO) cards, and fieldbus (Profibus/Modbus) adapters.

5. Installation and Maintenance
5.1 Installation Guide
- On-site Survey: Confirm cabinet space, temperature range, power supply voltage, and grounding conditions.
- Cabinet Installation: Fix in a standard 19-inch cabinet using shockproof gaskets.
-
Wiring:
Power-On and Self-Test: Turn on the power and observe the LED status indicators (Power, Comm, Alarm).
- Power Supply: Connect dual-power input, check polarity and grounding.
- Measurement: Connect CT/VT, calibrate phase and proportional coefficient.
- Communication: Connect to the control room switch via optical fiber or copper cable.
- Configuration: Import logical node configuration using the SCD (Substation Configuration Description) file provided by GE, or manually set via the GUI.

5.2 Maintenance Points
|
Item
|
Maintenance Content
|
|---|---|
|
Hardware Inspection
|
Regularly check the cooling fan of the power module, the cleanliness of fiber optic connectors, and the grounding resistance.
|
|
Firmware Upgrade
|
Perform OTA upgrade via GE Digital Power Studio or Web UI to ensure compatibility with the latest IEC 61850‑9‑2 standard.
|
|
Log Analysis
|
Regularly export operation logs (Syslog, IED Log) and analyze alarm trends.
|
|
Backup
|
Perform offline backup of configuration files (SCD, SCL) and databases monthly.
|
|
Security Audit
|
Audit user permissions, password policies, and TLS certificate validity quarterly.
|
|
