Description

GE MiCOM P441 | Alstom Agile Distance Protection System Numerical Relay

Part of the MiCOM P40 platform, the GE Micom Agile P441, P442, and P444 numerical full scheme distance relay provides flexible, fast, and reliable protection of transmission and sub-transmission lines. They include full scheme 6-zone distance, plus aided directional earth fault (DEF) and comprehensive backup protection for utility lines and cables at all voltage levels, particularly oriented towards transmission grids.
These distance protection systems are ideal for single circuit breaker application, single and/or 3-pole tripping, and include a full suite of monitoring, control, and recording capabilities plus fault locator, auto reclose, and check synchronism.

Micom P40 Agile

Enhanced Ethernet board module with switchable Ethernet redundancy delivered in a single model. The new board module is supported on P442 and P444, also delivered along with the NERC CIP v6 Cybersecurity release, software 91.
It supports PRP, HSR, and RSTP in one model, allowing a single P40 model to be used in any application requiring redundant Ethernet communications.
The new module is designed to handle high-density traffic in the IEC 61850-8-1 network, with time latency halved. Larger architecture digital substations can also be supported, with up to 50 nodes now possible in IEC 62439 HSR rings.

Key Features & Benefits:

• Universal IRIG-B – Modulated and demodulated supported in the same model
• HSR Ring – Extended to 50 node support for larger substation architectures
• Fast performance, particularly in onerous applications such as where process bus GOOSE is used for tripping purposes
• NERC CIP cybersecurity including role-based access control (RBAC), RADIUS and SysLog

GE Micom P441 Relay Key features:

• Dual algorithm distance operation for maximum fault detection dependability
• Deploy in traditional CT/VT applications or digital substation architectures with merging units and non-conventional instrument transformers using IEC 61850-9-2 process bus
• Distance to fault location assists dispatching of maintenance crews
• Full-scheme relay offers fast, discriminative response to double-circuit, cross-country, and evolving faults
• No internal batteries in GE-branded models – removes a maintenance item and eases air-freight logistics
• NERC CIP cybersecurity including role-based access control (RBAC), RADIUS and SysLog
• Advanced binary inputs comply with the harshest norms for surge withstand, plus the ESI 48-4 EB2 standard. Spurious wiring pickup is eliminated without the use of interposing relays, external resistors, or time delays. Battery/wiring faults, switching noise, and induction from long parallel circuits are tolerated without misoperation
