A model definition containing only equations is called a primitive block definition, while a model definition with a graphical block diagram is referred to as a composite block definition.
PowerFactory – DIgSILENT
If a block is drawn, the slot icon is automatically deactivated so that slots and blocks cannot be mixed dogsilent in the same diagram and vice versa if a slot is drawn first. As a result of this function, all graphical representations of the block definition are deleted.
Use the following command to get a data point: The function AddVars can be used in one of two ways: We will go through each tab and the functions that are available.
For example, Figure 5. Both primitive and digeilent block definitions can be reused inside other higher-level model definitions PowerFactory supports an arbitrary number of layers.
The following results should be seen in the output win- dow: Note that not all of the variables and signals in a model need to be manually initialised. We can first create a composite model and link it to the composite frame we tutrial earlier see Figure 2.
Equations window of the block definition dialog box There are three statements available for setting initial conditions: Structure digsildnt an ElmRes object The number of rows represents the total number of time intervals for the simulation. Tutprial equations for the wind turbine model are as follows: This solution enables a Python script to have access to a comprehensive range of data available in PowerFactory: Data Management in PowerFactory.
Consider the frame in which the composite block is located and how it will be connected to other slots.
General Software Information
However, if the inc0 statement is used, then PowerFactory assumes that the signal is not connected and initialises it using the inc0 expression. If no bus is found, then null digeilent returned.
The other advantage of GetFromStudyCase is that if the object does not exist inside the study case, the function will create it. Rather than impose restrictions, the philosophy adopted by PowerFactory is to provide tools for error detection and testing instead. Now we will have a look at what else digsilfnt inside the Python command object.
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. Block definition for a hydro turbine Figure 4. The string format determines the details of the event call, and which of the three options above applies: There are type objects in the library i. This can be any object, e.
Model definitions are type objects that belong in the equipment type library. You can access these parame- digsilsnt as if they were from any other type of object, i. It is implemented in DSL using a linear i difference approximation, plus a state variable x: A common model inherits the block diagram of the linked model definition, but has its own local parameter settings.
Printing initial values from the variable set dialog Figure 5. It is recom- mended that the steady-state load flow is configured correctly before running a time-domain simulation. There can be more than one graphical representation of the same object across many diagrams, though not in a single diagram. The Python command dogsilent can contain other objects within it.
