Though describes mapping on the specific communication protocol, there is still no description of ifc model to be implemented, data sets, sampling and transmission rates, time synchronization methods to be used.

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.

IEC 61850-9-3: Will simplicity supersede complexity?

This is done not to restrict any possible practical implementations. This is the main difference between and LE.

Any manufacturer could go on implementing products with specific solutions in aforementioned aspects. But this also led to the situation when there have been 618850-9 commercial products available on the market.


This is not a standard — this is technical requirements, more like an agreement between all interested parties manufacturers, end customers, etc. This document strictly defined those aspects iev and parts allowed flexibility data model, data sets, sampling and transmission rates, etc.

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

When IEC compliant devices will be available on the market? When one is creating a standard, one of the main goals is 618509- provide time invariance of standardized aspects. These and several other questions in relation to IEC are addressed in this paper.

This is also the case with IEC IEC Will simplicity supersede complexity? Its common to address this communication model in terms of a protocol: 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.

From to he was a Research Assistant with the Institute of Sensor and Actuator Systems, VUT, conducting research in the field of miniaturized sensor technology.

But what does this mean for the planning of future substation environments? From to he worked as Hardware Test Engineer 61805-9 Hardware Developer for major companies active in the automotive industry.

IEC Will simplicity supersede complexity?

For example, new time synchronization methods, sampling rates and etc. One of the communication models defined is transmission of sampled value data described in part 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.


In the eic years he worked as development engineer and product manager for major companies in the digital broadcast industry. Or will we face a battle of profiles?

What is the difference between IEC and IEC LE? | Digital Substation

Get support Contact form Offices and Partners. Though users have to keep in mind that those aspects, strictly fixed in IEC LE, may change as time goes by. What’s new Press Releases. 61850–9

Will simplicity supersede complexity? This could led to interoperability issues and to the whole range of IEC products at the end customer facilities with different 68150-9.
