ABB 630 series industrial power distribution systems

ABB 630 series industrial power distribution systems

DESCRIPTION

The 630 protection and control series of relays is a member of ABB’s  Relion® product family. The 630 series relays are characterized by their  functional scalability and flexible configurability.

Flexible adaptation to application-specific  requirements

The 630 series relays can be used in either single  or double-busbar applications with one or two  breakers and numerous switching devices.  They also support a substantial number of both  manually and motor-operated disconnectors and  earthing switches. Consequently, the 630 series  relays can be used to control various types of  switchgear.

The 630 series relays offer predefined  configurations, designed to match the most  typical protection and control requirements for  fast and easy setup. The pre-configurations  can be used as such or easily tailored to meet  application-specific requirements – with  freely selectable functions – using the  IEC 61850-compliant Protection and Control  IED Manager PCM600.

Human-machine interface

The 630 series relays are equipped with a large  graphical display that can show customizable  single-line diagrams (SLD) with position  indication for the circuit breaker, disconnectors  and the earthing switch. Also measured values  provided by the configuration can be displayed.  The SLDs can be flexibly adjusted to meet user  requirements using PCM600 and accessed not  only locally but also via the web browser-based  human-machine interface (HMI).

The 630 series HMI is distinguished by fifteen  three-color LEDs and five configurable push  buttons that can be used as control buttons for  various tasks, such as blocking, adjusting setting  groups or triggering the disturbance recorder.  The five push buttons can also be conveniently  used as menu shortcuts. Another distinguishing feature is the detached HMI, as an option  to the integrated HMI, which is highly beneficial  from a wiring perspective due to the large  number of IOs the 630 series relays are  equipped with.

Standardized communication

The 630 series relays fully support Edition 1  of the IEC 61850 standard for communication  and interoperability of substation automation  devices. The relays also support the DNP3  (TCP/IP) and IEC 60870-5-103 communication  protocols and are able to use two protocols  simultaneously. The supported communication  protocols, including IEC 61850, offer seamless  connectivity to various station automation  and SCADA systems.

The implementation of the IEC 61850 standard  covers both vertical and horizontal  communication, including GOOSE messaging  according to IEC 61850-8-1 with both binary and  analog signals. Analog GOOSE messaging enables  fast transfer of analog measured values over  the station bus. This facilitates, for example,  sharing of RTD input values, such as surrounding  temperature, with other relays. GOOSE messaging  is an alternative to traditional hardwiring signaling  for exchanging interlocking information between  the relays. For time-critical applications, the 630  series relays support synchronization over  Ethernet using SNTP or over a separate bus  using IRIG-B.

Main customer benefits

• Flexible solution for demanding utility and  industrial power distribution systems with  integration of protection, control, monitoring  and supervision in one relay 

• Wide application coverage – feeder, transformer,  motor and generator protection and control 

• Functional scalability and flexible configurability  – easy tailoring of convenient pre-configurations  to application-specific requirements with  freely selectable functions• Fast GOOSE messaging according to IEC 61850  for less interpanel wiring and supervised  communication 

• Detached HMI – as an option to the integrated  HMI – beneficial from a wiring perspective  because of the large amount of IOs  

• Large graphical display for showing  customizable SLDs, accessible either locally  or through a web browser-based HMI 

• Extensive life cycle services

Application

REF630 has been designed to be the main  protection for overhead lines and cable feeders,  in either isolated neutral, resistance-earthed,  compensated or effectively earthed distribution  networks. The comprehensive feeder  management relay offers four predefined  configurations, intended for open/closed ring  feeder applications, radial overhead/mixed line  feeder applications, ring/meshed feeder  applications and bus sectionalizers.

The earth-fault protection has been significantly  extended, now including not only directional  and non-directional, transient/intermittent,  wattmetric and admittance-based, but also both  harmonics and multifrequency admittance-based  earth-fault protection. The new additions take  the earth-fault protection to new heights,  creating an extensive earth-fault protection  portfolio. In addition, the sensitivity of the  intermittent earth-fault protection has been  significantly improved and reactive power  undervoltage protection added.

REF630 also includes a fault locator that locates  short circuits in radial distribution networks and  earth faults in effectively and low-resistance  earthed ones. If the fault current is as high as or  higher than the load current, earth faults in  isolated neutral distribution networks will also  be located.

Product highlights

• Extensive earth-fault protection portfolio with  unique multifrequency admittance-based  protection for higher sensitivity and selectivity 

• Advanced and fast fault location of short  circuits and earth faults
