Standardized communication

As a standard feature, PCMU MSOC supports the IEC 61850

standard for communication between devices within the subs

tations along with the industry standards DNP 3.0 and Modbus

protocols. The implementation of the IEC 61850 substation

communication standard in PCMU MSOC encompasses both

vertical and horizontal communication, including GOOSE mes

saging and parameter setting according to IEC 61850-8-1. The

substation configuration language enables the use of enginee

ring tools for automated configuration, commissioning, and

maintenance of substation devices.

Pre-emptive condition monitoring

For continuous knowledge of the operational availability of the

PCMU MSOC features, a comprehensive set of monitoring

functions to supervise the relay health, the trip circuit, and the

circuit breaker health is included. The breaker monitoring can

include checking the wear and tear of the circuit breaker, the

spring charging time of the breaker operating mechanism and

the gas pressure of the breaker chambers. The relay also mo

nitors the breaker travel time and the number of circuit breaker

operations to provide basic information for scheduling breaker

maintenance.

Protection and control

The PCMU MSOC is the most powerful, advanced and simplest

feeder protection relay in its class, offering time and instantane

ous overcurrent, negative sequence overcurrent, phase discon

tinuity, breaker failure, thermal overload, and voltage metering

and protection. The relay features optional high impedance fault

(HIZ) and sensitive earth fault (SEF) protection for grounded and

ungrounded distribution systems. The relay incorporates a flexi

ble three-phase multi-shot auto-reclose function for automatic

feeder restoration in temporary faults on overhead lines.

The PCMU MSOC integrates basic control functionality, which

facilitates the control of one circuit breaker via the relay’s front

panel human machine interface (HMI) or remote control system.

To protect the relay from unauthorized access and to maintain

the integrity of information, the relay has been provided with a

four-level, role-based user authentication system, with individual

passwords for the viewer, operator, engineer, and administrator

levels. The access control system applies to the front panel

HMI, embedded web browser based HMI, and the PCM600

relay setting and configuration tool.

control relay perfectly aligned for the protection, control,

measurement, and supervision of utility substations and

industrial power systems, designed to replace the ABB

legacy Microshield overcurrent (MSOC) relay. The relay

provides exact wire-alike matching rear terminals as the

existing MSOC relay, saving time and engineering. This

wire-alike feature makes the PCMU MSOC the ideal solution

for upgrading to the industry’s latest technologies. The

PCMU MSOC is a retrofit solution based on REF615 relay

from the proven Relion® family. The 615 series relays are

characterized by their compact and withdrawable design.

Application

REG630 has been designed to be the main

protection for synchronous generators, offering

full protection during start-up and normal run

for both the generator and the prime mover.

The comprehensive generator management relay

is typically used in small and medium-sized diesel,

hydroelectric, combined heat and power (CHP),

and steam power plants. REG630 offers one

predefined configuration, intended for directly

connected generator sets. REG630 has been extended with low-voltage

ride-through, reactive power undervoltage and

voltage vector shift protection to further ensure

grid stability and reliability, and thus avoid grid

collapse. The low-voltage ride-through protection

allows monitoring of distributed generation

during low-voltage fault ride-through, in order

to determine whether and when to disconnect,

for instance, a solar or wind farm from the grid.

Also the reactive power undervoltage protection

does the same but specifically at the grid

connection point, whereas the voltage vector

shift protection detects islanding from the grid.

An optional RTD/mA module offers eight

analog RTD or mA measuring inputs and four

mA outputs. The RTD and mA inputs can be

used for temperature measurement of generator

bearings and stator windings, thus extending the

functionality of the thermal overload protection

and preventing premature aging of the generator

windings. They can also be used for measuring

the ambient air or coolant temperature. The four

mA outputs can be used for transferring freely

selectable measured or calculated analog values

to devices provided with mA inputs.

Motor protection and control REM630

REM630 has been designed to protect medium-sized and large asynchronous

and synchronous motors in the manufacturing and process industry.

Product highlights

• Motor protection both during motor start-up

and normal run, with protection and fault

clearance also in abnormal situations

and large asynchronous and synchronous

motors requiring differential protection
