Need for One Standard

EASUN REYROLLE

The objectives that set for the making the standard were:

•A single protocol for complete substation considering modeling of different

data required for substation.

•Definition of basic services required to transfer data so that the entire

mapping to communication protocol can be made future proof.

•Promotion of high interoperability between systems from different vendors.

•A common method/format for storing complete data.

•Define complete testing required for the equipment's which confirms to the

standard

EASUN REYROLLE

Data Modeling -- Complete functionality of the substation is

modeled into different standard logical nodes which can be grouped

under different logical devices. There are logical nodes for

data/functions related to the logical device (LLN0) and physical

device (LPHD).

Reporting Schemes -- There are various reporting schemes

(Buffered Report Control Block & Unbuffered Report Control Block) for

reporting data from server through a server-client relationship which

can be triggered based on pre-defined trigger conditions.

Fast Transfer of events -- Generic Substation Event (GSE) are

defined for fast transfer of event data for a peer-to-peer

communication mode. This is again subdivided into GOOSE & GSSE

Setting Groups -- The setting group control Blocks (SGCB) are

defined to handle the setting groups so that user can switch to any

active group according to the requirement.

Sampled Data Transfer -- Schemes are also defined to handle

transfer of sampled values using Sampled Value Control blocks

(SVCB)

Commands -- Various command types are also supported by IEC

61850 which include direct & SBO commands with normal and

enhanced securities.

Data Storage-- SCL (Substation Configuration Language) is defined

for complete storage of configured data of the substation in a

specific format.

Interoperability is the ability of two or more IEDs from the same vendor, or different vendors, to exchange information and uses that information for correct co-operation.

Interchangeability is the ability to replace a device supplied by one manufacturer with a device supplied by another manufacturer, without making change to the other elements in the system

“Interchangeability is beyond IEC 61850”
