ALSTOM NUMERICAL GENERATOR PROTECTION RELAY AGILE P14DG

Type: Numerical Relay

Protection Type: Generator

P40 Agile Feeder Management

The P14N non-directional feeder, P14D directional feeder and P94V voltage and frequency IEDs bring the design rigor and technology of transmission applications to the entire utility and industrial market. The footprints of both the device physical size and the lifecycle environmental impact have been minimized using state-of-the-art design, component, and process selection. Agile solutions from GE are ideal for new-build and retrofit alike.

Agility and Versatility

MiCOM P40 Agile IEDs provide an integrated solution for the complete protection, control and monitoring of electrical power systems. Application for overhead lines, underground cables, busbars, breakers, transformers, reactors and distributed generation is supported, right from distribution (as primary protection) to transmission voltage levels (as back-up). The IEDs are suitable for a wide variety of applications in solidly-earthed, resistance-earthed and Petersen coil systems.

Key Benefits

  • Comprehensive current, voltage, power and frequency protection
  • Multi-stage independent protection elements, customizable curves
  • Universal power supply, binary input ratings and 1A/5A CT – avoids order options
  • Records up to 2048 events, graphical logic engine, distance-to-fault location
  • Two stage circuit breaker failure and breaker condition monitoring
  • Switchgear supervision including CT/VT, DC supply, full ‘H7’ trip circuit supervision
  • Substation communications including IEC 61850, serial and concurrent protocols
  • Compact, withdrawable design for reduced space applications
  • Ecodesigned with Product Environmental Profile (PEP), no resident battery

GE 489 Generator Protection System

The SR489 Generator Protection System, a member of the SR family of relays, provides protection, control and advanced communications in a cost effective industry leading draw-out construction. Designed for small and medium sized generators, the 489 delivers advanced protection including generator stator differential protection. The 489 also includes detailed diagnostic information allowing for reduced troubleshooting time.

Key Benefits

 

  • Complete, secure protection of small to medium sized generators
  • Easy to use generator protection supported by industry leading software tools.
  • Advanced protection and monitoring features including the use of RTDs for stator and bearing thermal protection and Analog Inputs for vibration monitoring
  • Draw-out construction allowing for minimized downtime and easy removal/installation of the 489 during maintenance routines
  • Large, user-friendly front panel interface
  • Enhanced generator troubleshooting through the use of IRIG-B time synchronized event records, waveform capturing, and data loggers
  • Simplified setpoint verification testing using built in waveform simulation functionality
  • Cost effective communication through industry standard hardware (RS232, RS485, 10BaseT Ethernet) and protocols (Modbus RTU, Modbus TCP/IP, DNP 3.0)

GE/ ALSTOM P442 NUMERICAL DISTANCE PROTECTION RELAYS

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
