2021年2月PSCAD V5正式发布,这是自X4版本之后大的一次版本更新,本次更新了大量的功能,修复了大量的bugs。同时还发布了PRSIM电力数据格式转换软件,PowerFactory或PSSE格式的数据,通过PRSIM轻松转换成适用于PSCAD软件的格式。
The World's Most Advanced Tool for Power Systems EMT Simulations
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.
并行高性能计算
除了现有的HPC功能外,V5还包括一个增强的并行网络接口(PNI),可连接以不同时间步长运行的进程。此外,并行多运行(PMR)功能也得到了增强,包括设置大和覆盖项目设置的能力。
Background
When digital programs were first developed for power system analysis, the computers available were the old mainframe type used by the company for their accounts and billing. A team of specialists, whose function was to oversee all transactions involving the system, also serviced the system. The technical user was but a slave to the whims of these specialists, whose power lay in their ability to speak the system language: The interpretation of a mysterious jumble of words known only as 'JCL' was a jealously guarded secret. Consequently, the 'end user' (or more humiliatingly the 'client') was kept in hand and normally suffered through the computer programs so condescendingly provided.
These computer programs were supposedly structured to anticipate, as the programmers hoped, the every need of the technical user. Model construction and variation was accomplished by data entry. Unfortunately, it was impossible to anticipate all needs. Developments in power system technologies out-sped advancements in the computer programs. Because of these limitations in program flexibility, the programs always lagged in representation of the emerging power system. The creative potential of the technical specialist could not be fully realized with such program modeling restrictions.
