However there is not straightforward way of creating local title block objects via a Python script. Tutoorial is the name that the object will be called inside the Python script.
A transient simulation is performed over this system considered all generator without controls Remember me on this computer. A tooltip will appear with the corresponding variable name.
PowerFactory – DIgSILENT
If this is possible, then the calculated g should be the same as the g initialised in the turbine block. The template title block can be any title block in the graphics board. This is to avoid returning the internal nodes of a subsection, and instead returning the main busbar.
ComPython internal template object You can use an internal object inside the Python command object as a template for the object type you want to create.
This steady state representation is shown in Figure 4. Obviously, you could do this manually using the export command i. The Python command object can contain other objects within it. We can create a new common model based on the AVK block diagram and replace the Basler controller in the composite model all the while using the same composite model and frame. This tutorial is a simple introduction to transient simulation with PowerFactory kB 3. For example, consider Figure 4.
Skip to main content. Activate Note that if there are subfolders within the study case folder, then further processing needs to be done to access the study case objects within these subfolders. It can be used for model parameters as well as internal signals. O8 Here we want to add the variable V to objects O1 to O8 i.
A block definition can be assigned as a macro by ticking the macro checkbox in the block definition dialog. This example is a simple introduction to dynamic model of constant digsiilent wind turbine in PowerFactory The following steps should then be followed to set up the results files, run the FFT and accessing the results.
We still need to create actual instances of the equipment inside the grid. In order to use this command, you must first locate the folder or object that you want to copy the template into. Primitive blocks are often re-used in other composite model definitions.
Rather than impose restrictions, the philosophy adopted by PowerFactory is to provide tools for error detection and testing instead.
The Pack function therefore creates a self-contained block definition object without any external references. This website provides digsielnt set of my experiences on use of PowerFactory.
In the hydro turbine example, we saw that the turbine slot was connected to turorial syn- chronous machine and governor slots. Column 1 in the Results file is the time of the simulation. Once the external template object has been selected, you can use the AddCopy object name command to create a new object in the database.
This is because the outputs of the model are usually known e. The same composite model as seen from inside the data manager is shown in Figure 2. The expression Tdelay must evaluate to a time indepen- dent constant and may digsildnt only consist of constants and parameter variables.
For the generator slot, we can select the relevant generator element in the grid. One reason to employ a remote script is if you have multiple study cases using the same script code, but different input parameters.
Works only with fixed limits, i. There can be more than tutoeial graphical representation of the same object across many diagrams, though not in a single diagram. The output pt is therefore known and we need to manually initialise the input g.
It is best practice to store elements such as common models and measurement devices inside the composite model object for example, see Figure 2. These documents are not for commercial purpose.
General Software Information
Composite frames are purely graphical and contain no equations. It is recom- mended that the steady-state load flow is configured correctly before running a time-domain simulation. This is generally for variables or signals that cannot be determined directly from the load flow solution. This example show the correct use of ElmFile to provide a wind speed time series into wind power dynamic simulations in PowerFactory Suppose that both generators use the same type of Basler voltage controller.
For example, hovering over the power factor field in the static generator element yields the variable name: This function will return an object with a reference to the top level of project folders, e. IntGrf- con and can typically be found inside a GNO: We can see from this stylised system that there are control signals i.
The results file is structured as a 2d matrix as shown in the figure below. I tried to put together in pedagogical way. First, find the template title block and add it as an external object to the Python command object.
