Ongoing Work on <strong>IEC</strong> <strong>61850</strong><br />
<strong>Edition</strong> 2<br />
• Preparation work started for <strong>Edition</strong> 2 of<br />
<strong>IEC</strong> <strong>61850</strong>-7-410 – the object models for<br />
Hydro Power plants<br />
• Consideration of development of<br />
communications models and interfaces<br />
for Distribution Automation by Working<br />
Group 17<br />
• TC 57 is looking into publishing all<br />
models in an electronic way. A task force<br />
is currently preparing a specification for<br />
online access to the data models, which<br />
shall be ready for the TC57 plenary<br />
meeting in spring 2010 for decisions.<br />

Technical Reports <strong>IEC</strong> <strong>61850</strong>-90-x<br />
• A technical report <strong>IEC</strong> <strong>61850</strong>-90-1 that<br />
will be published this fall will describe the<br />
use cases of applications that require<br />
information exchange between<br />
substations.<br />
• Examples: line differential protection or<br />
distance protection with blocking<br />
schemes.<br />
Page: 7
Technical Reports<br />
• A technical report <strong>IEC</strong> <strong>61850</strong>-90-2 that<br />
will describe the use of <strong>IEC</strong> <strong>61850</strong> for<br />
applications that require information<br />
exchange between substations and<br />
control center.<br />
Page: 8
Technical Reports<br />
• <strong>IEC</strong> <strong>61850</strong>-90-3 shall describe the<br />
aspects of using <strong>IEC</strong> <strong>61850</strong> for condition<br />
monitoring of power equipment.<br />
• The modeling of the information<br />
gathered by condition monitoring<br />
devices will be an essential part, but the<br />
specification of a mapping for a sensor<br />
bus might be included in that work as<br />
well.<br />

Technical Reports<br />
• <strong>IEC</strong> <strong>61850</strong>-90-4 Technical report:<br />
Network Engineering Guidelines<br />
• Will provide definitions, guidelines, and<br />
specifications for the network<br />
architecture of <strong>IEC</strong> <strong>61850</strong> based<br />
systems<br />

Technical Reports<br />
• <strong>IEC</strong> <strong>61850</strong>-90-5 Technical report:<br />
Prepare a harmonized specification for<br />
the transmission of synchrophasors<br />
based on IEEE C37.118 standard using<br />
<strong>IEC</strong> <strong>61850</strong>.<br />
• That work has been recognized by the<br />
US NIST (National Institute of Standards<br />
and Technology) as one of the top<br />
priorities for the introduction of Smart<br />
Grid.<br />

New Documents Planned<br />
• Documents describing the use of logical<br />
nodes for modeling of application<br />
functions<br />
• <strong>IEC</strong> <strong>61850</strong>-7-500 – use of LN to model<br />
functions in substation PAC systems<br />
• <strong>IEC</strong> <strong>61850</strong>-7-510 – use of LN to model<br />
functions in hydro power plant<br />
Page: 14
New Work Item Proposal<br />
• Functional testing of the system that<br />
implements distributed functions is an<br />
important issue<br />
• The purpose is to achieve automatic<br />
testing<br />
• A formal description of the behavior is<br />
required for this<br />
