Will simplicity supersede complexity?
What is the difference between IEC 61850-9-2 and IEC 61850-9-2LE?
Its common to address this communication model in terms of a protocol: During his time as hardware developer he was intensively engaged with time synchronizing technologies for digital TV and radio transmitters in single frequency networks.
When one is creating a standard, one of the main goals is to provide time invariance of irc 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. This is also the case with IEC Any manufacturer could go on implementing products with specific solutions in aforementioned aspects. 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 done not to restrict any possible practical implementations. This could led to interoperability issues and to the whole range of IEC products at the end customer facilities with different specifics.
In the following years he worked as development engineer and product manager for major companies in the digital broadcast 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. 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.
IEC Will simplicity supersede complexity?
Get support Contact form Offices and Partners. When IEC compliant devices will be available on the market?
IEC Will simplicity supersede complexity? For example, new time synchronization methods, sampling rates and etc. Or will we face a battle of profiles?
Rod Hughes Consulting Pty Ltd
These and several other questions in relation to IEC are addressed in this paper. Lec document strictly defined those aspects where and parts allowed flexibility data model, data sets, sampling and transmission rates, etc.
But this also led to the situation when there have been no commercial products available on the market. From to he worked as Hardware Test Engineer and Hardware Developer for major companies active in the automotive industry.
Though nobody cancels backward compatibility postulate. This is not a standard — this is technical requirements, more like an agreement between all interested parties manufacturers, end customers, etc.
IEC 61850-9-3: Will simplicity supersede complexity?
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. Iev is the main difference between and LE. But what does this mean for the planning of future substation environments?
