Relion REG670 Generator Protection Commissioning Manual Version 2.2 IEC – 1MRK502073-UEN

Description

The Relion REG670 Generator Protection Commissioning Manual Version 2.2 IEC is the field document that takes a REG670 generator protection IED from a cold, un-energised cubicle to a fully verified protection scheme ready for service. Published by Hitachi Energy under document ID 1MRK502073-UEN, Revision N, dated March 2024, and covering product version 2.2, this is the working reference for protection engineers, commissioning technicians, system engineers and maintenance personnel dealing with REG670 installations. The chapters are organised in the chronological order in which the IED should actually be commissioned, so the manual can be followed step by step at site or used selectively during service and maintenance work.

• Glossary

Read as a whole, the REG670 commissioning manual gives a technician the complete sequence for bringing a generator protection terminal into service. It starts with a commissioning checklist and power supply verification, moves through energisation and PCM600 communication set-up, and then walks through the wiring checks — CT circuits, VT circuits, RTXP test switch use, binary input and output circuits, and optical connections — before going into setting configuration and the injection based protection functions. The secondary injection chapter is the technical heart of the document: it explains, function by function, how to measure operating limits of set values, verify re-trip and back-up trip times, check directional lines, confirm the pole slip, out-of-step, loss of excitation and under-impedance characteristics, and validate alarm, start and trip outputs against the configured logic. Every test instruction identifies the settings, the expected service values and the output signals that should appear or should not appear.

Injection Based Protection and the ICT Workflow

Two full sections are dedicated to the injection based functions that make the REG670 distinctive. The ROTIPHIZ section covers sensitive rotor earth fault protection and the STTIPHIZ section covers 100% stator earth fault protection, and both are built around the Injection Commissioning Tool inside PCM600. The manual explains how to install REX060 and REX061 or REX062, how to run the three measurement steps of the calibration, how to select a suitable calibration resistance, how to interpret the checks performed by ICT at the end of calibration, and how to test the measurement using known test resistances with the generator at standstill. It then explains how to acquire reference impedances from ICT logfiles captured across a complete sequence of generator operating conditions — standstill, start-up, synchronisation, loaded operation, shutdown — and how to compare those logfiles against disturbance recordings and event lists to define the settings, blocking logic and switching times.

Communication, Directionality and Maintenance

Separate sections cover establishing and verifying SPA/IEC, LON, IEC 61850 and IEEE C37.118/1344 communication, including optical budget calculations for each link type. A dedicated directionality chapter explains how to compare the direction indication reported by the distance protection against the actual power flow measured by external equipment. The commissioning and maintenance section sets out periodic test cycles, alarm testing, self-supervision checks, trip circuit checks and measurement of service currents, and the troubleshooting section explains how to read the self-supervision signals, use the LHMI hint menu, and re-configure hardware after modules are added, removed or moved.

What This Manual Lets You Do

• Work through a REG670 commissioning from the checklist to the final trip test without leaving the document
• Configure analog CT inputs, I/O module supervision and the application configuration correctly before energising
• Install, calibrate and commission the ROTIPHIZ rotor earth fault and STTIPHIZ 100% stator earth fault injection based protection functions using ICT
• Verify every protection function by secondary injection and confirm measured operating values against the settings
• Bring up and verify SPA, IEC 60870-5-103, LON, IEC 61850 and IEEE C37.118/1344 communication links
• Check directionality of the distance protection after the object is energised
• Run periodic maintenance tests, self-supervision checks, trip circuit checks and service current measurements
• Diagnose internal failures and warning conditions from the self-supervision signals and the LHMI hint menu

Why the Correct Commissioning Reference Matters

Generator protection sits between a high-value machine and the network, and a REG670 that has been set, wired or tested incorrectly is worse than no protection at all. The procedure, the setting value and the test point all matter: a phase-to-phase test point one step outside the zone boundary, a reference impedance switched at the wrong operating condition, or a blocking time shorter than the transient it is meant to cover will all produce a scheme that behaves unpredictably in service. This manual gives the correct procedure for each of those decisions in the manufacturer’s own wording, so that measured values can be compared against the expected values, settings can be validated against site conditions, and every test result can be recorded as part of the commissioning evidence for the station.

Instant PDF Delivery

The Relion REG670 Generator Protection Commissioning Manual is supplied as a PDF download. There is no shipping, no waiting for a courier and no physical book to lose in the cubicle — the file is available immediately after payment and can be opened on a laptop, tablet or phone at the panel, printed page by page for a test record, or kept on a shared drive for the whole commissioning team. Because the chapters follow the order in which the IED is actually commissioned, the same file can be used on the first SAT and again years later for a periodic maintenance test.
