2. CIGRE Green book / reference book projects
Purpose:
CIGRE has decided to launch a collection of scientific and technical books to assemble the corpus of the knowledge of the members, beyond its present publications (ELECTRA, TBs, Session papers)
Objectives and targets:
CIGRE is the international reference in the domain of power systems. This scientific collection will be the basis of the works done by CIGRE.
International influence:
The collection will strongly contribute to the international standing of CIGRE, which will be the opportunity to create new partnership.
Communication objective:
Propagation of CIGRE works though Green book will provide an image of CIGRE as an organization which is open, creative, visible, that favors innovations

3. CIGRE Green book / Reference book project
TC editorial team is composed of the Secretary General, the TC Chairman (Mark Waldron), Konstantin Papailiou (B2) & Pierre Argaut (B1).
The target is to publish two Green Books per year based on CIGRE works. The books have between 500 to 700 pages approximately.
TC suggested that the Green books should be of high technical values. The selection of authors is made according to their personal knowledge.
Once published, these books could be used as a textbook in universities. CIGRE would provide the books as a gift at related events to inform other organizations of our technical activities and knowledge.
(CIGRE will celebrate 100 year anniversary in 2020)
CIGRE will get money from this publication, not pay for it.
CIGRE will decide one publisher in 2014: Elsevier, Springer, Wiley, Hermes Penton, etc. Elsevier is the preferred bidder at this moment.

4. CIGRE Green book progress in several SCs
SC B2 and B1 are the most advanced SCs in preparation of Green Books. The target for the two first Green books is ready for 2014.
SC B1 is preparing four books with different subjects: (a) Accessories, (b) Underground cables, (c) Submarine cables, (d) Offshore wind power generation (joint Reference book with B1/B3/C4).
SC B2 is planning one book covering all subjects related to OHLs and progressing correctly.
SC B3 is planning two books: Substation and SF6 issues, possibly for 2016.
SC B5 will prepare an unbiased book on Protection, even though the members (manufacturers) already published some books on the market, often commercial. SC B5 is expected for 2016 or 2018.
SC A3 and D2 discussed the topic during the SC Meetings.
Other SCs will follow.

5. CIGRE Green book discussions at TC
A3 chairman attended the B2 meeting during the Auckland symposium and informed A3 members of the information on the purpose of the book.
The books would be used as a gift for non-CIGRE members, such as Universities and other organizations such as CIRED, where there would be potentially future members of CIGRE, beside the purposes shown by CIGRE CO. Also it will be published as electronic forms as well as book, so the existing members can access the information by internet.
The copyright issue is applied to the same rules as those for CIGRE Session papers, ELECTRA articles and Technical Brochures.
SC A3 chairman continues his efforts to explain the A3 members about the purpose and importance of the Green book project.
Konstantin Papailiou will join the discussion with the A3 members at the next SC A3 advisory meeting in Delft to assist the process. However, his sudden business prevents him so he will find another opportunity.

6. CIGRE SC A3 Green book contents First proposal
First proposal: A3 will create one single book to cover all equipment subjects as the same style as one by B2.
Introduction of A3 & HV equipment
Transients phenomena in power systems
Simulations for HV equipment
Circuit breakers
Disconnectors
Earthing switches
DC circuit breaker & DC switchgear
Surge Arresters
Capacitor banks  (equipment aspects)
Series Capacitors  (equipment aspects)
Instrument Transformers
Fault Current Limiters
Reliability of HV equipment
Ageing & overstressing aspects
Emerging technologies of HV equipment
etc.
The proposal received some oppositions from a couple of A3 members due to too much anticipated works at the SC A3 meeting in Auckland, 2013.

7. CIGRE SC A3 Green book contents Alternative proposal
Alternative proposal: A3 will develop a few separate books to cover specific equipment subjects, upon a volunteer basis.
For example, there are two first suggestions:
(a) Circuit Breakers (along with other substation equipment)
Definitions, Principles for different technologies, Arc models, Switching duties & testings, Controlled switching, Reliability, etc.
(b) Surge Arresters (MOSA)
Definitions, Principles, Requirements, Duties, Testings, etc.
Some countries such as Brazil has published CIGRE textbooks on some subjects including the A3 scope. 7

8. CIGRE SC A3 Green book schedule tentative proposal
Call for experts: March 2014 (start-up after Delft AG meeting if agreed)
Call for editorial teams: March 2014
Preparation and collection of documents: March 2015
Preparation of additional documents: March 2016
Review of each document and improvement: December 2016
Editorial works for publication: December 2017
Submission for publication: March 2018
… A3 Green book will be revised periodically according to recommendations by AG.
