Registering SimAuto
SimAuto must be registered in the Windows Registry before it can be referenced from external programming platforms. This normally happens automatically when Simulator is installed, but may need to be performed again if there is a hardware change or if you are working with multiple versions of Simulator. (Only one version of SimAuto may be […]

D-FACTS Quick-Start Tutorial
Distributed Flexible AC Transmission System (D-FACTS) devices or “smart wires” change the effective line impedance of the transmission line on which they are installed. The Knowledge Base Article is a quick-start tutorial that introduces D-FACTS devices and how to use them in PowerWorld Simulator. This is a short hands-on training session with slides and sample cases. […]

Comparing Contingency Results
The Knowledge Base Article will cover how to take several contingency analysis runs done on the same system topology under different conditions and then build an Microsoft Access database that uses a query to compare the results across different contingency runs. Creating a Test Example of Three Different Contingency Analysis Runs on the same case […]
