How to create a measurement file for DIgSILENT PowerFactory from a CSV, TXT, or XLSX file?

How to create a measurement file for DIgSILENT PowerFactory from a CSV, TXT, or XLSX file?

Many times when you model time-domain simulations in DIgSILENT PowerFactory you want to use time-series data stored in CSV, TXT, or XLSX files. In PowerFactory you can integrate these time series by means of measurement files (*.ElmFile). These measurement files are simple ASCII files with a column for each variable including the time. The time…

Automatized short-circuit analysis with Python in DIgSILENT PowerFactory

Automatized short-circuit analysis with Python in DIgSILENT PowerFactory

Sometimes you want to know the short-circuit currents and short-circuit powers at different locations in the power system. This could be of importance for different reasons. For example, design of protection systems or identification of weak grid areas in terms of short-circuit power. Therefore, in this post, I present an approach for automatized short-circuit analysis…

How to check the consistency of PMU data?

How to check the consistency of PMU data?

The first thing before analyzing phasor measurement unit (PMU) data is to check its consistency. PMU data shall be checked for missing samples and consistency of the measurements. Missing samples are timestamps, for which no measurement value was recorded. The definition of data consistency is not as easy because there are many possible inconsistencies. For…
