Use the following command to get a data point: In order to access a study case, you must first access the study case folder. Whereas the block definition could be seen as the design or model for a piece of equipment, the common model can be seen as a specific physical instance of the equipment item itself e. This section collects some documents in short presentations form.
Stores the value x Tnow and returns the value x Tnow-Tdelay. Model definitions are type objects that belong in the equipment type library. Create a composite model and fill the slots with the relevant grid elements, e. The step response of the first-order lag block tutkrial shown in Figure 4. The relevant system components, e. SetVipage to create a new virtual instrument with the function GetVI string name, string class, int create.
The script then checks to see if it has a local title block and adds one if it does not. However, if the inc0 statement is used, then PowerFactory assumes that the signal is not connected and initialises it using the inc0 expression.
Similarly, accessing data for a particular time requires the row number for the relevant time interval. It is sufficient to simply be aware that they exist and know that the definitions are here for reference. It stores only the file path of the script and not the code itself. To create the object, you can use the AddCopy object name command. The general process is as follows: The slots for the generator, governor, turbine and voltage controller now need to be filled.
Ticking the checkbox will activate the feature, however it requires tuhorial additional configuration to make it work properly. It is important to note that if a macro needs to be altered after packing, the modifications must be done to the local macro inside this folder and not to the macro in the global library, other project, etc.
Therefore, to complete this model we need to manually initialise vw. Accessing to Two-Dimensional Matrix of Turbine. This block diagram represents the model definition for the voltage controller. Before going through this tutorial, the user should already have a basic grasp of PowerFactory handling and performing simple tasks such as load flows and short circuit simulations.
Now we will have a look at what else is inside the Python command object. The following subsections describe the three ways to see model signals and variables that are available in PowerFactory.
The use of the inc statement is straightforward and can be illustrated by example. SetDesktopso a relevant graphics board object needs to be retrieved before export- ing to a WMF. For example, when creating a transformer, the user must create both a transformer type e.
Some DSL syntax guidelines to keep in mind when creating model definitions: Brackets [ and ] are used to indicate the inclusion of the end points in the range, and are used to indicate the exclusion of the end points from the range. This steady state representation is shown in Figure 4. Related Posts
