1. Description

REM630 is a comprehensive motor

management IED for protection, control,

measuring and supervision of medium and

large synchronous and asynchronous motors

in medium voltage industrial power systems.

REM630 is a member of ABB’s Relion®

product family and a part of its 630 series

characterized by functional scalability and

flexible configurability. REM630 also features

necessary control functions required for the

management of industrial motor feeder bays.

The supported communication protocols

including IEC 61850 offer seamless

connectivity to industrial automation systems.

2. Application

REM630 provides main protection for

synchronous and asynchronous motors and

the associated drives. The motor management

IED is intended for circuit-breaker and

contactor controlled medium sized and large

synchronous and asynchronous motors in a

variety of drive applications, such as motor

drives for pumps, fans, compressors, mills,

crushers, etc.

The pre-defined configuration developed for

REM630 can be used as such or easily

customized or extended with add-on

functions, by means of which the motor

management IED can be fine-tuned to exactly

satisfy the specific requirements of your

present application.

Figure 1. RET630 and REM630 IEDs applied for the incoming feeder and primary switchgear

in a single busbar arrangement. The RET630 with preconfiguration A is used for

protection and control of the power transformer, the REM630 IEDs with

preconfiguration A are used for the circuit-breaker and contactor operated motor

feeders. The motor start-up signal from each REM630 is connected to the “Restart

inhibit” inputs of the other REM630s. Hence while one motor is starting-up, the

starting of the other motors is inhibited.

3. Preconfigurations

The 630 series IEDs are offered with optional

factory-made preconfigurations for various

applications. The preconfigurations

contribute to faster commissioning and less

engineering of the IED. The

preconfigurations include default

functionality typically needed for a specific

application. Each preconfiguration is

adaptable using the Protection and Control

IED Manager PCM600. By adapting the

preconfiguration the IED can be configured

to suit the particular application.

The adaptation of the preconfiguration may

include adding or removing of protection,

control and other functions according to the

specific application, changing of the default

parameter settings, configuration of the

default alarms and event recorder settings

including the texts shown in the HMI,

configuration of the LEDs and function

buttons, and adaptation of the default single-

line diagram.

In addition, the adaptation of the

preconfiguration always includes

communication engineering to configure the

communication according to the functionality

of the IED. The communication engineering

is done using the communication

configuration function of PCM600.

If none of the offered

preconfigurations fulfill the

needs of the intended area of

application, 630 series IEDs

can also be ordered without

any preconfiguration. In this

case the IED needs to be

configured from the ground

up.

4. Protection functions

REM630 offers all the functionality needed to

manage motor starts and normal drive

operations also including protection and fault

clearance in abnormal situations. The motor

management IED features motor run-up time

supervision, locked rotor protection and

protection against too frequent motor starts.

Furthermore, the IED offers thermal overload

protection, phase unbalance protection,

stabilized differential protection for motors,

high-impedance or flux-balance-based

protection, three-phase directional overpower

protection, underexcitation protection, load-

based motor jam protection, loss of load

supervision, and phase-reversal protection.

REM630 also incorporates non-directional

and directional earth-fault protection, rotor

earth-fault protection and back-up

overcurrent protection. The IED also offers

optional negative and positive phase

sequence overvoltage protection, positive

phase sequence undervoltage protection,

underfrequency and overfrequency protection.

In certain motor drives of special importance

there must be a possibility to override the

motor thermal overload protection to perform

an emergency start of a hot motor. To enable

an emergency hot start, REM630 offers a

forced start feature.
