GE Vernova\’s latest MiCOM P440 series models P441 to P444 inclusive offer an ideal path to refurbish an older installed base of MiCOM P440 relays. Whether those older products were initially sold as GE VERNOVA 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 Vernova 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

For more than 100 years, electric power plants have mainly been large, utility-owned facilities, feeding distributed load based on unidirectional power flow. Over the past 20 years, smaller, independent power generation plants have been developed and distributed within electrical networks. The increasing number of Distributed Generation (DG) sites, and their increasing power ratings from kW to hundreds of MW, create new challenges for network planning and operation.

Distributed Generation Tee Infeeds to Existing Transmission Lines

Circuits near the coast may be candidates for tee infeeds to evacuate renewable energy from onshore and offshore wind generation. A tee infeed to a nearby transmission line can be a more cost effective solution to connect the generation to the grid than building a new substation. This economy enables more Distributed Generation connections to penetrate the network helping to meet green energy connection targets and reduce greenhouse gas emissions.

Multi-Ended Circuit Differential Lines

Previously transmission and distribution circuits would have two or three ends only. However, five or more ends are becoming common because large Distributed Generation sites such as onshore or offshore windfarms and solar farms are being connected to the grid. As the power networks evolve to transport power in ever more complex ring and meshed networks, line/cable differential protection becomes increasingly attractive, with its inherent ability to address grading/selectivity challenges and is scalable for multi-terminal circuits able to accommodate many connections of distributed generation along the line. GE Vernova’s Grid Solutions’ multi-ended current differential protection is now ready for any protection topology from two to six terminals, whether those multi-terminals exist now, or are provisioned for connection in the future.

Functional Block Diagram

• Powerful graphical Programmable Scheme Logic (PSL) customise relay logic
• Real-time monitoring of remote, local and differential per-phase currents
• Oscillography - 48 samples/cycle, up to 10.5 seconds record length
• Event Recorder - 1024 time tagged events, time tagged to a resolution of 1 ms

Programmable Scheme Logic

Powerful graphical logic allows the user to customise the protection and control functions. The logic includes 32 timers, gates (OR, AND, MAJORITY) and set/reset latch functions, with the ability to invert the inputs and outputs and provide feedback.

The system is optimised to ensure that the protection outputs are not delayed by PSL operation.  The programmable scheme logic is configured using the graphical S1 Agile software. The relay outputs may be configured as latching (lockout) or self-reset. All aspects of MiCOM P40 IED configuration are managed using the S1 Agile software.

Measurement and Recording Facilities

All events, fault and disturbance records are time tagged to a resolution of 1 ms. An optional IRIG-B port is available for accurate time synchronisation.

Power System Measurements

Instantaneous and time integrated voltage, current and power measurements are provided. These may be viewed in primary, or secondary values.

Fault Location

A fault location algorithm provides distance to fault in miles, kilometres, ohms or percentage of the line length. The proven algorithm employed tolerates pre-fault loading and fault arc resistance.

Event Records

Up to 1024 time-tagged event records can be stored. An optional modulated or demodulated IRIG-B port is available for accurate time synchronisation.

fault Records

The last 15 fault records are stored.

Disturbance Records

The oscillography has 16 analogue channels, 64 digital and 1 time channel, all at a resolution of 48 samples/cycle.

• Advanced IEC61850 Edition 2 implementation with complete settings via SCL files
• Embedded IEEE 1588 time synch protocol support eliminates dedicated IRIG-B wiring requirements for IEDs
• Redundant communications with zero downtime using optional PRP/HSR protocols
• Wide range of supported protocols Courier/K-Bus, IEC 60870-5-103, DNP 3.0 (EAI-485 or Ethernet) and IEC 61850

Protection Communications Interfacing

To ensure compatibility with standard communications equipment, the MiCOM P54x Agile multi-ended line differential series is designed to work with IEEE C37.94TM. A direct fibre optic connection to a MUX is possible if the MUX is IEEE C37.94TM compliant.

In direct fibre optic applications, 1300 nm and 1550 nm channel options are available. The transmitters are designed with a large "optical budget" to support up to 150 km.

Communications Supervision

Dependable communications are essential for high-performance differential protection. Each active longitudinal channel is independently monitored and reports error statistics in line with guidance from ITU-T G.821.

Multi-ended line differential works in a ring connection, which provide comms redundancy. In the event of degraded communications, the ring communications channels will continue to provide protection, thus providing duplicated links via diverse communications paths.

Alternatively, back-up overcurrent elements can be switched into service, either as permanent parallel main protection, or temporary protection only during channel outages.

Communications with Remote Operators and Substation Automation

Rear Scada Communication

The wide range of communications options, including IEC 61850, provides interfacing with almost any type of substation automation system or SCADA system.

The following protocols are available:

• Courier/K-Bus
• IEC 60870-5-103
• DNP 3.0 (EAI-485 or Ethernet)
• IEC 61850 Edition 2

P54x devices can be enhanced with an optional redundant Ethernet board. The redundancy is managed by the market's fastest recovery time protocols: IEC 62439-3 PRP and HSR allowing bumpless redundancy and RSTP, offering multi-vendor interoperability. The redundant Ethernet board supports either modulated or demodulated IRIG-B and the SNTP protocol for time synchronisation. The redundant Ethernet board also has a watchdog relay contact to alarm in case of a failure.

Second Rear Courier Port

An additional second rear port can be ordered as an option, designed typically for dial-up modem access by protection engineers/operators when the main port is reserved for SCADA traffic. This port also offers the option of -103 communications when IEC 61850 is the chosen first port protocol.

Monitoring & Diagnostic

The T60 includes high accuracy metering and recording for all AC signals. Voltage, current, and power metering are built into the relay as a standard feature. Current and voltage parameters are available as total RMS magnitude, and as fundamental frequency magnitude and angle. For power quality applcations, harmonic measurements (up to the 25th) for voltage and current are available. T60 can monitor, calculate and log hottest-spot temperature, aging factor and loss-of-life data over a long period. This data, combined with economic analysis, allows criteria to be developed regarding the best time at which to replace a power transformer due to load growth, i.e. to minimize the cost without significantly increasing the risk.

Advanced Automation

The T60 incorporates advanced automation features including powerful FlexLogic™ programmable logic, communication, and SCADA capabilities that far surpass what is found in the average transformer relay. The T60 integrates seamlessly with other UR relays for complete system protection.
