ConnectivityIndustrial process supervision

Month DD, Year | Slide 2© ABB Group

The connection of low voltage devices in communication networks is typically required in:

automated industrial processes

large industries

oil & gas applications

smart grid networks

Specifically, the capability of combining the control of the industrial process with the supervision of the electrical plant which supplies it is becoming increasingly important.

ConnectivityIntegration into systems


Low voltage CBs equipped with advanced electronic trip units provide digital communication on several protocols

In this way it is possible to connect LVCBs into supervision and control systems

LVCBs not only for protection of distribution plants but also for supervision and control

ConnectivityDistribution plant supervision


LVCB as a sensor/actuator in a supervision system

Some advantages:

Measurement of power/energy for cost optimization and allocation

Remote control of circuit breaker

Measurement of power quality (power factor, THD, interruptions/sags)

Diagnostic data of the circuit-breaker (e.g.: % contact wear) to schedule preventive maintenance

Remote information about the circuit-breaker state

Remote alarms/warnings to reduce downtime of the plant

ConnectivityField bus connection


Most used fieldbus protocols with LVCBs:


ConnectivityModbus RTU

Modbus RTU

It is an open, serial protocol derived from the Master/Slave architecture.

It is widely used within Building Management Systems (BMS) and Industrial Automation Systems (IAS).

Modbus RTU is wide accepted because:

It is an ease of use and reliable protocol

It is an open and royalty-free protocol


ConnectivityProfibus DP

Profibus DP (Decentralized Peripherals)

It is a standard for fieldbus communication in automation technology

It is a master/slave protocol used to operate sensors and actuators via a centralized controller

It is mainly used in factory automation.

Centralized controller (PC/PLC)

Slaves


ConnectivityDeviceNet

The DeviceNet

It is a master/slave communication protocol in multidrop network

designed to connect simple devices (e.g sensors, actuators) and automation systems in general.

It is mainly used in industrial applications for communication between PLC and motor starters, motor controllers, drives.

Fieldbus Connection The use of Ethernet technology is increasingly being used because:

Adopted worldwide

High data baudrate (up to 100 Mbit/s)

Common use of infrastructure and integration with Internet/Intranet

Wide availability of devices and standard components (e.g.cables/switches/hubs)

Easy of use and integrate industrial devices from different vendors

Simple to integrate with networks that already exist in the business office environment

Compatibility with many standards

Ability to connect and address more devices over longer distances and wider areas. This can be crucial in large plant environments

ConnectivityIEC61850

IEC61850 has been designed with specific characteristics, suitable for the applications related to electrical power (e.g. electrical substations). Two ways of communicating between devices: horizontal (GOOSE) and vertical (MMS) communication.

The standard has defined a real language that describes the informative content of the devices in a significant way from the point of view of the application.
