EMTDC现在包括一个改进的增强节点分析(MANA)算法。这样就可以实现电压/电流相关的电压/电流源(包含在V5主库中)。此外，还实现了一种新的稀疏解决方案，这在求解较大的子系统时是有益的。如果子系统中的节点数量**过200(默认值)，则自动使用新的解决方案。
System Dynamics
The system dynamics is an essential part of the EMTDC solution process. It serves to encompass the electric network, providing the ability to interface with it on either side: Data may be controlled from one side, while extracted from the other.
Essentially a Fortran program in its own right, the system dynamics is built according to customizable specifications. These specifications are normally provided through PSCAD, in the form of components and modules. Components and modules are graphical representations of how the final program is to be structured, where each module, including the main page, is represented by a unique Fortran file. This file consists of declarations for a DSDYN subroutine, a DSOUT subroutine, and two BEGIN subroutines. Components always exist within modules, so as such they represent inline code that combines to define the contents of each subroutine.
Of course, some components are electrical in nature and hence provide information for the construction of the electric network as well. This information is collected and inserted into a Data file, where each module in a project possesses its own unique Data file. Data files are discussed in more detail later on in the section entitled Electric Network Solution.
As power systems evolve, the need for accurate, intuitive simulation tools becomes more and more important. With PSCAD you can build, simulate, and model your systems with ease, providing limitless possibilities in power system simulation. Included is a comprehensive library of system models ranging from simple passive elements and control functions to electric machines and other complex devices.
