EMTDC vs. Other EMTP-Type Programs
The electric network solution in EMTDC and some other EMTP-type programs, are based on the principles outlined in the classic 1969 paper by Hermann Dommel [1]. However, EMTDC has been independently developed from these other programs.
Virtually all power system models and techniques used in other EMTP-type programs are available in EMTDC. Some of the major differences between EMTDC and the other programs are listed as follows:
The free edition utilizes our newly developed, centralized licensing manager — a cloud-based solution, which licenses the application through certificates. By design, a certificate allows the user to run the software without being continuously online.
An EMTDC simulation begins at a specified start time and finishes at a specified end time. Between these two times, the program performs the same sequential process iteratively, each iteration incrementing the time by a specified interval. This interval is referred to as a time step, which remains constant (i.e. fixed) during the course of the simulation.
As illustrated by Figure 2-1, the core solution process begins and ends with the system dynamics. First, variables are initialized and stored in BEGIN. Dynamic functions are performed in DSDYN, which includes the preparation of electric network devices such as sources, etc., as well as the manipulation of control **s. The electric network is solved and the resulting measured quantities are considered, along with any post-solution processing requirements, in DSOUT, before the time step is incremented.
Of course, the complete EMTDC solution sequence is more involved than that shown in Figure 2-1. There are several other features present that ensure solution accuracy and speed; all of which are discussed in the following sections. A more complete program process is illustrated in Figure 2-2.
