What's New

MiCOM P40 Agile Explorer

Enhanced Ethernet board module with switchable Ethernet redundancy delivered in a single model.

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 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

Overview

The MiCOM Agile P543, P544, P545 & P546 range of transmission-class protection relays provide high speed current differential unit protection. They are designed for overhead line and cable applications, interfacing readily with the longitudinal (end-end) communications channel between line terminals. The interface options support direct fiber optic or multiplexed digital links.

Each of the models offer resident subcycle distance protection to complement the powerful suite of main and backup protection. Full scheme, five-zone distance protection is adopted from the class-leading MiCOMho MiCOM Agile P443. The product line becomes the standard in all HV, EHV and UHV line protection applications, duplicated where dual redundant main protection is demanded. Set any combination of differential, distance, overcurrent and reclosing, depending on the site needs. One universal relay type instead of two or more discrete models means reduced spares holding, less training, and lower cost. 

The MiCOM Agile P544 and P546 are suitable for the complex installation and feeders controlled by two circuit breakers such as breaker-and-a-half configurations with dual breaker autoreclose logic schemes with synchrocheck for both breakers.

Key benefits:

  • A universal relay that reduces spare holding - apply as a current differential relay, a distance relay, or both
  • Neutral differential boosts sensitivity of tripping for resistive earth faults, even for lines with heavy load-flow 
  • Transient biasing reduces CT knee point dimensioning by typically 25% compared to historical applications 
  • Differential protection adaptable to all different substation topologies: in-zone transformers and unequal line end CT ratios 

Main characteristics:

  • Comprehensive communication options including IEC 61850 Edition 1 and Edition 2
  • IEC 61850 redundant Ethernet, supporting self healing ring, RSTP, dual homing, PRP or HSR
  • Fast subcycle distance protection with quadrilateral or mho zones and setting free power swing detection
  • InterMiCOM64 for transmitting digital signals through teleprotection communication links

Refurbishment Solutions - "If it's Blue Think to Renew"

GE\’s latest MiCOM P540 series models offer an ideal path to refurbish an older installed base of MiCOM P540 relays. Whether those older products were initially sold as Alstom or AREVA-branded products, newer models retain pin-pin refurbishment capability. Advantageously, users can benefit from the advancements made in protection, control, communications, hardware and cybersecurity that have taken place in the intervening years. The new P40 retains form, fit and function compatibility but delivers the latest platform and software ready for today\’s environment, and for future-proofed application for the decades ahead.

Pin-Pin Upgrade Methodology:

  • Take the order code (CORTEC) of the older relay being removed, typically a blue case relay
  • Translate to today\’s latest GE MiCOM model, adding Ethernet options if required
  • Order the new P40 relay
  • Extract settings and logic, use S1 Agile toolsuite to convert settings
  • Detach the terminal blocks from old relay, leaving wiring attached / detach terminal blocks from the new.
  • Carefully examine the terminal blocks to see that no physical damage has occurred since installation
  • Mount new relay. Old relay blocks fit straight onto the new relay - safer, less wiring to reconnect.
  • It is recommended to apply rated current and voltage to the relay CT/VT inputs during secondary injection testing to check the continuity of the CT/VT terminal block connections to the relay.
  • Download converted files
  • Test, return circuit to service with only minutes of downtime

LFCB and MITZ Replacement:

  • GE\’s P545/P546 relays and P590 interfaces fit directly into the space vacated by our legacy relays, offering a perfect functional match
