Alstom GE Multifunction Servers

Part of the MiCOM P40 platform, the Agile P441, GE MiCOM Agile P442 and P444 numerical relay full scheme distance relays provide 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 includes a full suite of monitoring, control and recording capabilities plus fault locator, autoreclose and check synchronism.

Key features:

• Dual algorithm distance operation for maximum fault detection dependability
• Deploy in 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

The Agile P441, P442 and P444 have a settable quadrilateral operating characteristic that offers consistent 0.85-1.3 cycle zone 1 operating time for general distance application. Customers have a choice of cost-effective built-in teleprotection: InterMiCOM64 at 56/64 kbit/s for direct fiber or MUX links with 2 or 3 ended applications, or EIA (RS) 232 for MODEM links in 2 ended applications. The IEC 61850 redundant Ethernet supports self healing ring, RSTP, dual homing or PRP.

Alstom P442 Key benefits:

• Comprehensive communication options including IEC 61850 and redundant Ethernet ports
• IEC61850-9-2 interface option allows integration within digital substation process bus architectures
• Variety of built-in aided schemes over 2 channels
• Unparallelled speed, security and selectivity

The Multilin D20E is the next-generation input/output (I/O) module for substation automation and SCADA RTU applications, ideal for D20 I/O upgrade. As a non-edge device leveraging the latest technology in microprocessors, communications and applications, the D20E I/O can be deployed within an electronic security perimeter such as with a server (e.g. D20MX or D400) or with IEDs.

The D20E can also be used to replace legacy D20 I/O modules with minimal field wiring changes. The D20E has the same termination connector and alignment as the existing D20 I/O; this makes the D20E a practical and cost-effective solution for substation RTU and automation upgrades and retrofits.

Key benefits:

GE’s DS Agile Substation Gateway substation gateways perform the communication interface between the electrical substation and the area dispatch centers (SCADA), allowing SCADA operators to remotely control and monitor the substation in coherence with the operation of the whole area of the electrical grid.

The main functions of the DS Agile Substation Gateway are to transmit substation indications and measurements to the dispatch center, and dispatch centers’ commands to the substation control system. This is performed within the structure of the Energy Management System (EMS) of the overall grid.

Key benefits:

·         A multi-protocol gateway to interface with SCADA level

·         The Substation Gateway can manage up to 4 protocols and up to 8 channels

·         Rugged solution qualified for electrical substation

·         Interchangeable with former A300 model
