多实例模块(MIM)
用户可以轻松地复制和粘贴模型,甚至可以将模型保存在库项目中,跟其他元件一样,可以在多个案例项目中使用。
电路可以在模型内部复制并实例化。这样可以减少重复工作。
模型可以有参数,这些参数可以用于在不需要连接端口的情况下通过模型进出数据。
黑匣子模块
该特性将任何控制系统模块转换为等效的非模块组件,并配有生成的源文件和/或已编译的二进制文件。
黑匣子功能允许用户以图形方式设计他们的系统,并将系统设置为黑匣子,从而在向客户分发他们的模型时保护他们的知识产权。
EMTDC uses a Chatter Removal algorithm (related to the Interpolation algorithm) to remove these unwanted oscillations.
EMTDC does not restrict how circuit elements can be combined: Users can place any number of switching elements, sources, etc. in series or in parallel.
EMTDC switching devices and sources can be ideal (i.e. 0 resistance) or non-ideal (where the user can enter the on/off resistance values).
Change was on the way: Minicomputers and later personal computers came on the scene with new operating systems, which made all the hocus-pocus associated with using large scientific programs on the old mainframes, obsolete. Virtual memory replaced overlays. New graduates, no longer intimidated by the computer, were more than capable of dealing with any programming situation. Today, the technical expert has control over both the computer and its programs and is intimately involved in adapting both hardware and software to meet his/her requirements for investigation and analysis.
EMTDC was developed for this new and more acceptable environment, first specifically for UNIX/Linux, and then on to Microsoft Windows operating systems. Model building of control and electric systems is no longer defined entirely by data entry – with the program hidden, untouchable somewhere in the depths of the computer memory: Now the model is created by user Fortran statements. Time domain model components, such as AC machines, exciters, six-pulse valve groups, etc., are modularized into subroutines for easy assembly by the user. The user is able to build his or her subroutines, if and when models are not available.
With the advent of PSCAD, the graphical user interface for EMTDC, there is for the most part, no longer any need for the user to build his/her own subroutines through coding. Subroutine assembly and insertion into EMTDC is now performed automatically by PSCAD. The responsibility of the user has been reduced to graphically assembling a given network, and in some cases, adding some user-defined code. However, there may still be a need in some instances, such as the conversion of older subroutines, where a good knowledge of the internal structure and methods of EMTDC is important.
