For example, new time synchronization methods, sampling rates and etc.
This is 61850-99 a standard — this is technical requirements, more like an agreement between all interested parties manufacturers, end customers, etc. Or will we face a battle of profiles? 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. When IEC compliant devices will be available on the market?
What is the difference between IEC and IEC LE? | Digital Substation
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.
Though users have to keep in mind that those aspects, strictly fixed in IEC LE, may change as time goes by. From to he worked as Hardware Test Engineer and Hardware Developer for major companies active in the automotive industry. Any manufacturer could go on implementing products with specific 618509- in aforementioned aspects.
Though nobody cancels backward compatibility postulate. When one is creating a standard, one of the main goals is to provide time invariance of standardized aspects. This is the main difference between and LE.
Get 6150-9 Contact form Offices and Partners. 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.
During his time as hardware developer he was intensively engaged with time synchronizing technologies for digital TV and radio transmitters in single frequency networks. 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.
One of the communication models defined is transmission of sampled value data described in part But this also led to the situation iex there have been no commercial products available on the market. 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 61850-9-3: Will simplicity supersede complexity?
In the following years he worked as development engineer and product manager for major companies in the digital broadcast industry. Will simplicity supersede complexity? Its common to address this communication model in terms of a protocol: But what does this mean for the planning of future substation ied These and several other questions in relation to IEC are addressed in this paper.
This could led to interoperability issues and to the whole range of IEC products at the end customer facilities with different specifics. IEC Will simplicity supersede complexity?
This is also the case with IEC This is done not to restrict any possible practical implementations.
