How can I simulate a network with unsymmetrical voltages and different phase impedances?

Attached you find an example with 3 unsymmetrical voltage sources. It is required to use 3 symmetrical voltage sources and to connect them to the load busbar using 3 single-conductor cables (phase A…

What do "unsupplied areas" and "isolated areas" mean?

An "isolated area" is a node or a group of nodes which are connected to each other. Each isolated area is assigned to an index (Parameter Name b:ipat) and needs a load-flow reference (slack) of its…

How is the external grid modelled for RMS simulation?

It is modelled as a voltage source with an internal impedance. The mechanical equations are equivalent as those for the synchronous machine. The Acceleration Time Constant (in s) represents the…

How can I colour the text printed with DPL in the output window?

Strings are coloured using the following character sequence ∖cx, where "∖c" defines that the string should be coloured and "x" defines the colour to use. The list of available colours and an example…

How can I see the actual value of a parameter using DPL script?

Normally, when you access a variable in PowerFactory, the result of the DPL query is the value as entered in the element dialogue, e.g. oLoad:plini (the active power of a load). To access the actual…

How can I execute a calculation command in all the study cases?

Find attached a DPL (DIgSILENT Programming Language) script that performs the following tasks: Activation of the study cases, one by one. Search and execution of the command in the calculation case…

Can you provide an overview list showing all PowerFactory functions?

An overview of all PowerFactory functions is given in the PowerFactory brochure. The brochure also gives information about which functions are included in the base package and which functions require…

How can I export WMF files using DPL?

The attached example export all the VI (virtual instrument) pages to a specific folder as WindowsMetaFile (WMF) files. To use the script is necessary to have an active project and an active study…

How can I write a result file using a DPL script?

The attached project includes a DPL script that writes a result file. The result object is defined inside the DPL command. The scaling factor of the loads is changed between 0 and 1, a load flow…

How can I export a result file using a DPL script?

The attached project includes a DPL script that writes a result file and then export it into a comma separated values (csv) file. The result object is defined inside the DPL command. The scaling…
