IEC61850 digital protection at substation bay level

Dual-network redundancy and fast self-healing fiber ring for IEDs

Migration & Рекомендации по замене

ACE850FO is discontinued. New projects are not recommended for procurement; spare parts are limited to existing stock. New design options:

1. Upgrade to new-generation Sepam protection relays with built-in IEC61850 fiber ports, eliminating external ACE850 modules
2. Retrofit for existing Sepam40/80: evaluate full IED replacement or third-party optical-electrical converters (GOOSE latency must be validated)

Контрольный список устранения неполадок

1. Optical link: Inspect SC connector endface cleanliness, verify multi-mode fiber matching and optical power. 100BASE-FX does not work with single-mode fiber.
2. Ring network: RSTP configuration. Avoid multiple root bridges within one ring; guard against GOOSE storm.
3. Коммуникация: Distinguish S-LAN and E-LAN. E-LAN is for SFT2841 commissioning only; do not permanently connect to SCADA supervision network.
4. Login: Password reset requires factory reset, which erases all network configuration.
