Description
The DEP232.1 029.223003 is Alstom Grid’s legendary 32-bit Protection & Control IED that has guarded 400 kV substations for two decades—and still refuses to retire. One palm-sized module now fuses distance, differential, over-current, breaker-fail, synchro-check and auto-reclose into a single, cyber-hardened brain that speaks IEC 61850 GOOSE at light speed.
Application Scenarios
3 a.m. in the Saudi desert: a 380 kV line flashes to ground. The old electromechanical relay hesitates 180 ms, cascades three buses, and blacks out 1.2 GW. Swap in the DEP232.1 029.223003: 21 ms Zone-1 trip, GOOSE peer-to-peer lockout, and the grid yawns back to life before the coffee gets cold. The pain point—cascading blackouts—becomes a 0.00 % mis-operation trophy on the SCADA wall.

Technical Principles and Innovative Values
- Innovation Point 1: “K-Block” quadrilateral distance characteristic shrugs off 40 Ω fault resistance—covers 100 % of desert flashovers where mho circles fail.
- Innovation Point 2: Dual-algorithm differential (87L) runs alpha-plane AND charge-comparison—catches CT saturation in 4 ms instead of 40 ms.
- Innovation Point 3: One-box 8-bay breaker-fail logic—sends GOOSE trips to 16 peers in <3 ms, no copper wires, no auxiliary relays.
- Innovation Point 4: Built-in 1 GB COMTRADE vault stores 1,000 events at 96 kHz—turn every fault into a 4K forensic movie.
Application Cases and Industry Value
Case 1 – Egyptian 500 kV Backbone A 14-year-old P443 mis-tripped 11 times in one sandstorm. Engineers hot-swapped the Alstom DEP232.1 029.223003 during live traffic; the new IED rode through 52 Ω arcs, kept 2,100 MW flowing, and paid for itself in 19 hours of avoided penalties.
Case 2 – Norwegian Fjord Wind Farm Salt fog corroded old distance relays twice a winter. The DEP232.1 029.223003 lived on the offshore substation, absorbed 42 kV switching surges, and delivered 99.9998 % availability—adding 4.1 GWh/year and zero helicopter lifts.
