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 […]

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 […]

WECC Post Contingency Voltage Drop Criteria Monitoring

  Note, this knowledge base article provides a very simple feature for monitoring for voltage deviation monitoring, however if you need more flexibility than is shown below, there are two other knowledge base articles related to this one which provide much more flexibility than is shown below.  Links to these knowledge base articles are as follows. How […]
