Schneider Electric 2- Division - Name Date

Introduction

A major part of Schneider Electric strategy to differentiate its

products is

based on providing the most comprehensive set of communication options:

Multiple communication ports:

RS-232; RS-485; InfraRed

optical

port, Modem, Ethernet (100BaseTX

and 100BaseFX)

Multiple protocols:

ION; Modbus

RTU (slave / master);

Modbus

TCP; DNP 3.0, Ethergate,

Modemgate

and now IEC 61850

Where does IEC 61850 come from?

Substation situation

What are these challenges?

Lack of interoperability between devices high integration costs;

Limited vendor choice not always the best product for a particular need;

Multiple technologies working together high maintenance costs;

Why IEC 61850 is different

IEC 61850 protocol was created to take advantage of modern Ethernet switched

technology and, in addition to the specification of the protocol

elements (how

bytes are transmitted on the wire), IEC 61850 provides a comprehensive

model for how power system devices should organize data in a manner thatis consistent across all types and brands of devices:

Object model based on human understandable names: V Phase A

is 26.3 kV

instead of IED1, Obj

30, Var

4, #6 = Va;

Standardized data grouping based on function, rather than on

device type;

Self describing devices vendor provides a file with the devicesfeatures;

Standardized configuration language (SCL): precise definition of

a

devices role in a power system

Customer Benefits


7/12


Both ION 7550 and ION 7650 will support IEC 61850 protocol. The meters willprovide via 61850:

Operational metering data (V, I, PF, Power, Energy totals) and some powerquality parameters (harmonics, symmetrical components);

Access to read and write meter digital & analog I/O;

Custom mapping of ION values into 61850 in addition to standard models;

Up to 4 client connections

Reporting service for 61850 data: 1 buffered and 5 unbuffered

reports per client,

50 members max;

Additional features: COMTRADE waveform recording and time synchronization via

SNTO

ION modules:

Within the devices native ION architecture, specific ION modules map data to

each of the IEC 61850 logical nodes:

Summary:

High accuracy (0.2S) and Power Quality metering data are now available through

IEC 61850 protocol ION 7550 and ION 7650 PQ meters

This new feature will be available in the next firmware release (V360) and installed

meters can be upgraded on the field;

COMTRADE waveform formats are now available directly from the meter;

An FTP server is now available on the meter for transfer of IEC 61850 configuration

files and COMTRADE records;

IEC 61850 implementation on ION 7550 and 7650 meters are certified by Kema;
