What is the difference between IEC 61850-9-2 and IEC 61850-9-2LE?

When one is creating a standard, one of the main goals is to provide time invariance of standardized aspects. Though describes mapping on the specific communication protocol, there is still no description of data model to be implemented, data sets, sampling and transmission rates, time synchronization methods to be used. For example, new time synchronization methods, sampling rates and etc.

This could led to interoperability issues and to the whole range of IEC products at the end customer facilities with different specifics. Will simplicity supersede complexity?

But what does this mean for the planning of future substation environments? During his time as hardware developer he was intensively engaged with time synchronizing technologies for digital TV and radio transmitters in single frequency networks.


Though nobody cancels backward compatibility postulate.

Any manufacturer could go on implementing products with specific solutions in aforementioned aspects. To be time-invariant descriptions in are as general as they can be, describing control block structure and parameters to be transmitted in an abstract way. But this also led to 61850-99 situation when there have been no commercial products available on the market.

16850-9 This is done not to restrict any possible practical implementations. This is also the case with IEC This document strictly defined those aspects where and parts allowed flexibility data model, data sets, sampling and transmission rates, etc.

IEC Will simplicity supersede complexity?

Get support Contact form Offices and Partners. Or will we face a battle of ied Its common to address this communication model in terms of a protocol: In the following years he worked as development engineer and product manager for major companies in the digital broadcast industry. From to he worked as Hardware Test Engineer and Hardware Developer for major companies active in the automotive industry. What’s new Press Releases. Though users have to keep in mind that those aspects, strictly fixed in IEC LE, may change as time goes by.


One of the communication models defined is transmission of sampled value data described in part These and several other questions in relation 618850-9 IEC are addressed in this paper.

IEC Will simplicity supersede complexity?

This is not a standard — this is technical requirements, more like an agreement between all interested parties manufacturers, end customers, etc.

When IEC compliant devices will be available on the market?

This is the main difference between and LE. Based on the current implementation situation and the findings from the IEC interoperability plugfestthe paper explores the differences and commonalities of the two PTP profiles for power applications and their interoperability. From to idc was a Research Assistant with the Institute of Sensor and Actuator Systems, VUT, conducting research in the field of miniaturized sensor technology.
