What is the difference between IEC 61850-9-2 and IEC 61850-9-2LE?
Get support Contact form Offices and Partners. From to he worked as Hardware Test Engineer and Hardware Developer for major companies active in the automotive industry.
One of the communication models defined is transmission of sampled value data described in part This is the main difference between and LE. Its common to address this communication model in terms of a protocol: IEC Will simplicity supersede complexity?
When IEC compliant devices will be available on the market?
What is the difference between IEC and IEC LE? | Digital Substation
To be time-invariant descriptions in are as general as they can be, describing control block structure and 6180-9 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. This is 618850-9 a standard — this is technical requirements, more like an agreement between all interested parties manufacturers, end customers, etc. This document strictly defined those aspects where and parts allowed flexibility data model, data sets, sampling and transmission rates, etc.
What’s new Press Releases. Will simplicity supersede complexity?
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. But what does this mean for the planning of future substation environments?
This is done not to restrict any possible practical implementations. Any manufacturer could go on implementing products with specific solutions in aforementioned aspects. This is also the case with IEC During 6185-09 time as hardware developer he was intensively engaged with time synchronizing technologies for digital TV and radio transmitters in single frequency networks. In the following years he worked as development engineer and product manager for major companies in the digital broadcast industry.
For example, new time synchronization methods, sampling rates and etc. Though nobody cancels backward compatibility postulate. But this also led to the situation when there have been no commercial products available on the market.
These and several other questions in relation to IEC are addressed in this paper.
Or will we face a battle of profiles? When one is creating a standard, one of the main goals is to provide time invariance of standardized aspects.
IEC 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 specifics. 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.
Though users have to keep in mind that those aspects, strictly fixed in IEC LE, may change as time goes by.
