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.
我们为Red Eléctrica de España进行了345KV串
联电感器暂态恢复电压(TRV)的研究,高压输电线
路的故障限流以及暂态稳定改善方面有时候是需要串
联电感器的(虽然并不常用),串联电感器对断路器
的暂态恢复电压提出了挑战。由于串联电感器的安装
并不常见,所以每种情况必须仔细评估考虑断路器,
电容耦合电压互感器(CCVTs)和其他主站设备的位
置。在TRV这些类型的研究方面我们是非常的。
Manitoba作为加拿大有名的水电省,其中95%的
电力是由清洁可再生的水产生的。 作为Manitoba Hydro
的子公司,我们认识到可再生清洁能源的重要性。我
们协助客户完成世界各地的项目,并且在模型和仿真
发展和理解方面投入了很多年的精力,在这个领域依
靠自身的知识和经验成为。我们有的双馈感

公认为次同步谐振(SSR)和次同步交互控制的(SSCI)
行业筛选的标准。
Manit oba Hydro Int ernational Ltd.所能提供的项目研究以及给世界各
地的公司提供过的服务。
The first lines of code were written in 1975, at Manitoba Hydro by Dennis Woodford (Technical Director of the Centre 1986 - 2001), out of a need for a simulation tool that was sufficiently powerful and flexible to study the Nelson River HVDC power system in Manitoba, Canada.
Following the success of this study, development of the program continued through the next two decades. Over this time, a full spectrum of professionally developed models was eventually accumulated (as needed for various simulation projects) - in addition to various enhancements to the actual solution engine itself.
