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。
Conversion from Powerflow-type Data
Used in combination with an add-on product, PRSIM, PSCAD can
translate both PSS/E and DigSilent PowerFactory data file types,
directly into PSCAD format.
Consider the simple circuit in Figure 2-3. A comparator is being used to compare a real constant variable equal to 0.0, with a data signal Ea, which is a measured voltage from a voltmeter. The comparator is adjusted so as to give a high output when Ea becomes greater than 0.0, and a low output otherwise. The comparator dynamics are defined by default in the DSDYN subroutine, whereas the measured voltage signal Ea is defined in DSOUT as an output quantity.
With the above configuration, the comparator output signal will contain a single time step delay. This is due to the fact that the comparator dynamics in DSDYN (i.e. the code that determines its output state) are using a measured voltage Ea, defined in DSOUT. Since the comparator output state is based on the comparator inputs, the output will appear to have been delayed by one time step.
This delay can be removed simply by forcing the comparator dynamics code from DSDYN to DSOUT. This will force the comparator to consider the measured voltage within the same time step, when determining its state.
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:
超过20个新模型被添加到V5主库中。包括一个MMC模型库，一个相域同步机，一个单相感应机，和一个z域模型库。一个全新的3/5肢，二元概念为基础的变压器模型也包括。
