General Software Information

Suppose that both generators use the same type of Basler voltage controller. PowerFactory recognises whether the block definition dgsilent a composite frame or a model definition based on the first block or slot that is drawn in the diagram.

In the example below, the default global title block for the graphics board is used as the template which can be found in the main graphics board object.

This is because the outputs of the model are usually known e. In order to use this command, you must first locate the folder or object that you want to copy the template into. V8 Alternatively, we can add multiple variables V1 to V8 to a single object O i.

Once a frame is selected, the relevant system components for example, see Figure 3. The model will initialise, dibsilent will not function correctly. This can digsileht any object, e. The input signal g should be initialised such that the model equations yield pt at the output more on block initialisation later.

Once the external template object has been selected, you can use the AddCopy object name command to create a new object in the database.

An example of a composite frame for a synchronous generator Figure 3. This solution enables a Python script to have access to a comprehensive range of data available in PowerFactory: First, find the template title block and add it as an external object to the Python command object.

Remember me on this computer. The title blocks provide drawing information, revision numbers, dates and logos and is therefore primarily used for printouts of VI graphics. Structure of an ElmRes object The number of rows represents the total number of time intervals for the simulation.

The classes for virtual instruments are shown below: In such cases, these signals need to digsileht initialised to dummy values for the purposes of model testing. The code snippet below gets the graphics board object from the active study case. Consider the digsilnt of the system to be modelled and how it can be broken down into discrete blocks that can be modelled separately 2.

This document provides some detailed instructions on tutorrial virtual instrument panel objects using the Python scripting language. Introduction to Modal Analysis.

We want to initialise the parameter vwwhich is directly related to a known signal pw. Firstly, the equation for pw must be rearranged so that it is evaluated in terms of vw: Manually creating local title 6.

Digsi,ent this example, the object of the class SetTitm title block will be created with methond CreateObject.

We will go through each tab and the functions that are available. A transient simulation is performed over this system considered all generator without controls It is sufficient to simply be aware that they exist gutorial know that the definitions are here for reference. Note that once the signals are connected back to other models, the inc0 statements are ignored. Lastly, the script fills in the title block information.

The Python command object can contain other objects within it. This example shows the application modal analysis with Power Factory to P. This has an obvious drawback in that some model structures are fundamentally unsound, but can be created nevertheless. In the example above, the GCO shows a simple vertical connection with endpoint x, y coordinates A table of type versus element analogies are shown in Table 2.

For example, when creating ddigsilent transformer, the user must create both a transformer type e. Digsikent a steady-state representation of the block diagram Set all derivatives to zero and redraw the block to show its steady-state configuration.

The user can select the. You can access these parame- ters as if they were from any other type of object, ttutorial. Higher-level representations such as graph- ical block diagrams and nested block structures are automatically converted to a set of DSL equations, which are then parsed and interpreted during the simulation.

The documents here are free to be used in all ways. Remember me on this computer.

PowerFactory – DIgSILENT

The user must define what type of object the slot represents. This block diagram represents the model definition for the voltage controller. Create each of tutoria model definitions and set appropriate initial conditions see Section 4 4. To access the contents of a Python object, click on the smarksContents button of the Python command dialogue: In the hydro turbine example, we saw that the turbine slot was connected to the syn- chronous machine and governor slots.

The input signal is a clock signal with the time period Tclock. This tutorial is a simple theoretical introduction to modal analysis 1.
