Abstract
The Electromagnetic Transients Program (EMTP) is a common software for analyzing the electromagnetic transient phenomena, the electromechanical dynamics, and the control system transients in electric power systems and electronic circuits. Since the late 1960's, the EMTP has been developed by many contributors, and various capabilities, functions and auxiliary programs have been added to the EMTP. In the first half of the paper, history of Japanese EMTP Committee (JEC) and its activity is described. The basic policy of the JEC is “neutral” and “public domain”. The objectives, members, recent workshops and publications are introduced in this report. The activity of the JEC covers any EMTP version, such as ATP- and DCG-EMTP, derived from the BPA-EMTP. The second part of this paper presents the history and products of the EMTP Development Coordination Group Project (EMTP-DCG Project), which is organized to rationalize the development of the EMTP.
