EMTDC is a powerful electromagnetic transients simulation engine that has been evolving since the mid-1970s. Originally inspired by Dr. Hermann Dommel from his classic 1969 IEEE paper published in the Transactions of Power Apparatus and Systems, EMTDC development has been geared to many users in the power industry since inception. Electromagnetic transients simulation has changed greatly since the 1970's. The earliest versions of EMTDC were run at Manitoba Hydro on mainframe computers using punched cards. Only one or two cases a day could be submitted and run and so coding and program development were extremely slow compared with what can be accomplished today. As computers developed, more sophisticated file handling systems became available with text editors and cathode ray terminals. Today, the powerful personal desktop computers allow enable simulation that couldn't even be imagined 30 years ago. Roots? Many people have had a hand in developing EMTDC, and its graphical interface PSCAD. Many have come to refer to EMTDC, and PSCAD/EMTDC, as simply PSCAD. The original source code, and concepts developed in extending Dr. Dommel's equations to HVDC systems are the life's work of Dennis Woodford. Along with Dennis, many others have made significant contributions to PSCAD including the staff at the Who is using EMTDC? PSCAD now has over 1000 licenses of the software worldwide. Many users in utility planning and operations, equipment manufacturers, consulting engineers, and research laboratories are all using this software on a day-today basis. Where is EMTDC going? EMTDC has proven to be very efficient and robust and is used to solve many engineering problems, some in novel ways. The Centre, in cooperation with the University of Manitoba and our users are continually advancing …
