PowerFactory – DIgSILENT
This can be any object, e. Suppose that both generators use the same type of Basler voltage controller. This tutorial describes how import a project previously developed in PowerFactory 2. The Python command gutorial may contain objects or references to other objects available in the PowerFactory database. Note however that this function only works with the active study case.
This is a dogsilent file containing the P. However there is not straightforward way of creating local title block objects via a Python script. Process of simulation Part 1Part 2 Example of P.
The expression Tdelay must evaluate to a time indepen- dent constant and may therefore only consist of constants and parameter variables.
An understanding of numerical simulation, particularly the concepts of state-space representations and solutions to differential-algebraic equations DAE is also desirable, but not essential. Instead, the simplest way is to copy a template title block into a VI panel object.
In ditsilent to access cigsilent study case, you must first access the study case folder. Note that as mentioned earlier, there is already a built-in model for the synchronous generator element and therefore does not require an additional definition. To do this, use the following difsilent to search for the vigsilent column number: 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.
This document provides some detailed instructions on manipulating virtual instrument panel objects using the Python scripting language. In such cases, an iterative, numerical initialisation routine can be used.
This section contain a simple tutorial is designed to provide an introduction of Transient Simulation using PowerFactory software. For example, if the title block object is oTitle, then you can change the annex, title 1 and title 2 by accessing the variables oTitle: This is generally digsipent variables or signals that cannot be determined directly from the load flow solution.
There are few restrictions on how a user can construct models and with this freedom, a user can create models with very complicated structures.
The following results should be seen in the output win- dow: Frame showing a governor and turbine connected to a synchronous generator The initialisation process starts at the synchronous generator element, a grid element tutoroal a built-in model. Two model definitions each referenced by one common model one-to-one ing the structure of a simplified generator control system, and how it can be implemented in PowerFactory.
General Software Information
The delay time is 0. Modal analysis with PowerFactory. The CreateObject class name, object name function is used to create new objects.
We want to initialise the parameter vwwhich is directly related to a known signal pw. The classes for virtual instruments are shown below: Comments or suggestions are welcome. Create a composite model and fill the slots with the relevant grid elements, e. PrintPlain oFold Copy the template short circuit event into the events folder oFold.
Block definition packing and encryption functions 6. The variable names for each title block field is shown below: The external event must be stored locally in the DSL model. The state variable x should therefore be initialised to zero. The code snippet below gets the titorial board object from the active study case. The function returns a list of objects that meet the criteria in the string. We also have the option of initialising the internal signals that make up g i. Tutoial reason to employ a remote script is if you have multiple study cases using the same script code, but different input parameters.
Enter the email address you signed up with and we’ll email you a reset tutorrial. Construct a composite frame showing how the slots are interconnected 3. In such cases, these signals need to be initialised to dummy values for the purposes of model testing. This a computer aided engineering tool for the analysis of industrial, utility, and commercial electrical power systems. Using the VI object, use the AddVars function to add variables and objects to the plot. Accessing to Two-Dimensional Matrix of Turbine.
Works only with fixed limits, i. Help Center Find new research papers in: For example, consider a wind turbine model with inputs and outputs as shown in Figure 4. 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. 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.
Type and element analogies To provide a more concrete example, consider the two diagrams in Figure 2.
In the hydro turbine example, we saw that pt is connected to the synchronous generator and thus known from the load flow calculation. The level of detail required in the controller models will of course depend on the types of studies to be conducted, performance requirements, degree of influence the unit has on the network, etc. To get the value of these results you can use GetAttribute string method. However, if the inc0 statement is used, then PowerFactory assumes that the signal is not connected and initialises it disgilent the inc0 expression.
The following steps should then be followed to set up the results files, run the FFT and accessing tuforial results.
