This conference focuses on establishing global cooperation channels among researchers and engineers.

The third International Conference on Advanced Power System Automation and Protection (APAP 2009) was held from 18  to 21 October 2009 at the Lotte Hotel Jeju, Seogwipo, Jeju, Korea. The conference was organized by Next-generation Power Technology Center (NPTC) Korea Electrical Manufacturers Association (KOEMA).

The main goal of APAP 2009 is to establish global cooperation channels among researchers and engineers in the power system protection and automation field to share their experiences and knowledge.

An increased number of participants  attended this third APAP, thanks to the fact that the conference was organized as a joint event with the CIGRE study Committee B5 Colloquium 2009. The conference program reflected the much higher recognition of the importance of protection and automation technology due to recently emerging Smart Grid issues. APAP 2009 responded to this trend by a specially prepared panel session for Smart Grid.

APAP 2009 provided the new style session-Industry Special Session firstly introduced in APAP2007 which is dedicated to industry experts who used to feel uncomfortable about the academic conference.

The multiple papers were presented in several different types of sessions. The Intensive Oral Session gave the speakers 15 minutes for presentation. After all the speakers of this session finished their presentations, 40 minutes were provided for the session chairman to summarize the presented papers and to lead an intensive discussion on the topics of the session including questions and answers for the presented papers.

The Oral Sessions gave the speakers 15 minutes for presentation followed by 5 minutes for questions. A large number of papers were presented in Poster Sessions, when the authors stood near their poster during the duration of the session in order to discuss in detail their paper with the interested participants

An Industry Special Session allowed presenters to share their field experiences and new ideas in short presentations.

Companies exhibited their power system automation and protection related products in the halls where during the coffee breaks the participants had the opportunity to discuss the exhibited products and their applications.

After the end of the official  part - the technical program of the conferences, some of the participants enjoyed the extraordinary  beauty of Jeju Island during a half-day tour.
