C4 System Technical C4 System Technical PerformancePerformance

Scope further revisedScope further revised

SC C4 deals with methods and tools for analysis related to power systems with particular reference to dynamic and transient conditions and to the interaction between the power system and its apparatussub-systems between the power system and external causes of stress and between the power system and other installations Specific issues related to the design and manufacturing of components and apparatus are not in the scopes of SC C4 as well as those specifically related to planning and operation and control apart from those cases in which componentapparatussubsystem behaviour depends on or significantly interacts with the performance of the nearby power system

The fields on which the activity is carried include but are not limited to

Power Quality Electromagnetic CompatibilityElectromagnetic Interference (EMCEMI) Insulation coordination Lightning Advanced Tools for the analysis of power system performance Power systems dynamic performance models and analysis

Revised Strategic Plan for C4Revised Strategic Plan for C4

The proposal is for collapsing into three groups 1048707 One strategictechnical advisory group 1048707 One advisory group to liaise with other SCrsquos

and institutions (IEEE IEC CIRED etc) 1048707 One advisory group to help with the

dissemination of SC C4 achievementsresults namely to help with the organizing of tutorials workshops etc

7

New structure ndash General New structure ndash General concernsconcerns Some subjects may phase out if we do not properly focus on it One way to

address this is to have a balanced number of experts from each area in the technical AG

A contrasting comment was that we do not want to be too narrow in defining our scope because maybe in the current structure we are limiting our selves and not including new areas

It was expressed that this new approach is fruitful as it would allow more efficiency and greater interaction between the various technical areas

There is a concern about how big the single technical AG can be (practically) to be able to get a balanced view across the fields and still be effective

Another concern is that the scope of the subjects we deal with is too wide and so there is no best way to deal with a structure for such a committee so should we also deal with this issue

The overlap between the subject matters was thought by a few individuals to be perhaps 10-20 and so we may be going too far to collapse everything into a single technical group

In our group we have too broad areas (i) methods and (ii) tools so maybe we can have two technical groups in these areas

It seems superfluous to have the organizational AGs on liaisons and tutorials Maybe we should have two subcommittees (i) electromagnetic phenomena and

(ii) electromechanical phenomena ie based on frequency range of phenomena

New structure ndash General New structure ndash General concernsconcerns Some subjects may phase out if we do not properly focus on it One way to

address this is to have a balanced number of experts from each area in the technical AG

A contrasting comment was that we do not want to be too narrow in defining our scope because maybe in the current structure we are limiting our selves and not including new areas

It was expressed that this new approach is fruitful as it would allow more efficiency and greater interaction between the various technical areas

There is a concern about how big the single technical AG can be (practically) to be able to get a balanced view across the fields and still be effective

Another concern is that the scope of the subjects we deal with is too wide and so there is no best way to deal with a structure for such a committee so should we also deal with this issue

The overlap between the subject matters was thought by a few individuals to be perhaps 10-20 and so we may be going too far to collapse everything into a single technical group

In our group we have too broad areas (i) methods and (ii) tools so maybe we can have two technical groups in these areas

It seems superfluous to have the organizational AGs on liaisons and tutorials Maybe we should have two subcommittees (i) electromagnetic phenomena and

(ii) electromechanical phenomena ie based on frequency range of phenomena

New structure ndash General New structure ndash General concernsconcerns Some subjects may phase out if we do not properly focus on it One way to

address this is to have a balanced number of experts from each area in the technical AG

A contrasting comment was that we do not want to be too narrow in defining our scope because maybe in the current structure we are limiting our selves and not including new areas

It was expressed that this new approach is fruitful as it would allow more efficiency and greater interaction between the various technical areas

There is a concern about how big the single technical AG can be (practically) to be able to get a balanced view across the fields and still be effective

Another concern is that the scope of the subjects we deal with is too wide and so there is no best way to deal with a structure for such a committee so should we also deal with this issue

The overlap between the subject matters was thought by a few individuals to be perhaps 10-20 and so we may be going too far to collapse everything into a single technical group

In our group we have too broad areas (i) methods and (ii) tools so maybe we can have two technical groups in these areas

It seems superfluous to have the organizational AGs on liaisons and tutorials Maybe we should have two subcommittees (i) electromagnetic phenomena and

(ii) electromechanical phenomena ie based on frequency range of phenomena

New structure ndash General New structure ndash General concernsconcerns Some subjects may phase out if we do not properly focus on it One way to

address this is to have a balanced number of experts from each area in the technical AG

A contrasting comment was that we do not want to be too narrow in defining our scope because maybe in the current structure we are limiting our selves and not including new areas

It was expressed that this new approach is fruitful as it would allow more efficiency and greater interaction between the various technical areas

There is a concern about how big the single technical AG can be (practically) to be able to get a balanced view across the fields and still be effective

Another concern is that the scope of the subjects we deal with is too wide and so there is no best way to deal with a structure for such a committee so should we also deal with this issue

The overlap between the subject matters was thought by a few individuals to be perhaps 10-20 and so we may be going too far to collapse everything into a single technical group

In our group we have too broad areas (i) methods and (ii) tools so maybe we can have two technical groups in these areas

It seems superfluous to have the organizational AGs on liaisons and tutorials Maybe we should have two subcommittees (i) electromagnetic phenomena and

(ii) electromechanical phenomena ie based on frequency range of phenomena

Preferential Broad Subjects 2012Preferential Broad Subjects 2012 PS1 New generation technologies and their connection to the transmission and

distribution system modeling and case studies The impact of new generation technologies on the power quality of the network this

includes passive and active impacts positive and negative impacts dynamic and transient performance

Power quality and EMC issues in the transmission and distribution system related to the massive use of power electronics (this includes power electronics in the transmission system as well as large numbers of power electronics in the distribution system) and external agents

PS2 New and improved tools and techniques for power system performance analysis with particular reference to stochastic methods

Incorporating risk in analysis through probabilistic tools and assessment in light of the increasing complexity of future networks

Advanced numerical methods PS3 Lightning protection and insulation coordination as it relates to new generation

and transmission technology Wind turbines UHV systems HVDC systems Models for the calculation of lightning performance of transmission lines
