The attached example shows a small industrial grid where 1. At 0 seconds the connection to the external grid is opened 2. At 1 second the diesel unit is connected to the internal grid. Before it was…
It is possible to monitor the breaker status in a DSL model. The switches (StaSwitch) that are to be monitored must have the flag "detailed for calculation" enabled. This option is located in the…
An example is provided attached depicting a linear and a non-linear dynamic load model.…
You try to connect a power or current measurement device (StaPqmea or StaImea) but you get the message: "Selected Object NodeName 'Terminal' is not a 'Cubicle'". You have to select in this case on the…

This issue appears due to various errors occuring during the loading process of the specific DLL (dynamic link library) file. As with any other DLL based file, the architecture with which the DLL was…
The attached project shows how events can be created based on the status of the breaker. Please note that this works only if the breaker is set to "detailed for calculation". Else the breaker may be…
If the option "Current source model: Use negative sequence angle for negative sequence current source" is enabled, the negative sequence angle is either calculated internally or can be defined via the…
The objective is to limit the active power setpoint of a generation unit depending on the voltage measurement at a terminal. For this functionality, a two slightly different QDSL-Models that can be…

For lightning transient studies, the line insulators are represented by voltage-dependent switches. There are different options to model the flashover during lightning transients, such as: Voltage…
An example is provided in the project attached. The state machine is implemented in the block definition "StateMachine" and it is based on DSL statements. It represents a generic example of how the…
