Please make a reasonable use of this documents. In such cases, these signals need to be initialised to dummy values for the purposes of model testing. The equations for the wind turbine model are as follows: We can perform a similar exercise and define model definitions for the governor and turbine not shown vigsilent. Test the complete model see Section 5.

PowerFactory – DIgSILENT

A block definition can be assigned as a macro by ticking the macro checkbox in the block definition dialog. The general rule is that in the steady state, all derivates are zero, i. Please con- sider that the array has to be sorted in ascending order.

This creates a local title block for the VI panel. The CreateObject class name, object name function is used to create new objects. This website provides a set of my experiences on use of PowerFactory.

Prentice Hall, fifth edition, The Execute object function can then be used to execute the calculation. It is implemented in DSL using a linear i difference approximation, plus a state variable x: Gonzalez-Longatt over ten years of PowerFactory use.


General Software Information

These signals and variables will then be displayed in the data manager as shown in Figure 5. 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.

However there is not straightforward way of creating local title block objects via a Python script. How to access this result data please see Chapter 5. There is another type of graphical object that defines the connections between two objects e. This tutorial is a simple introduction to transient simulation with PowerFactory kB.

The code snippet below does the following: The inc0 statement is only exe- cuted if the signal is not connected and is typically used to test models in isolation or when the signal is not used, but needs to be initialised more on the use of inc0 in Section 5. Hydro Turbine Block Initialisation. Block definitions can be built from both equations and graphical block diagrams.

Part 1Part 2 Comments or suggestions are welcome: Manual initialisations must be entered in code form inside the equations window of the block definition dialog see Figure 4. Note that it may also be possible for the output signal g to be calculated using the model equa- tions from the speed input.

Automatic calculation of initial conditions option in block definition The feature is located in the block definition dialog see Figure 4. The delay time is 0.

Anderson 9 bus test system 1. Introduction to Transient Simulation with PowerFactory: Therefore, close the graphics board prior to executing any Python scripts that will manipulate title block objects.


The Python command object can contain other objects within it.

This example show the correct use of ElmFile to provide a wind speed time series into wind power dynamic simulations in PowerFactory The template title block can be any title block in the graphics board.

If a block is drawn, the slot icon is automatically deactivated so that slots and blocks cannot be mixed up in the same diagram and vice versa if a slot is drawn first. The signals pt and speed are calculated automatically based on the steady- state load flow solution and are known.

PowerFactory recognises whether the block definition is a composite frame or a model definition based on the first block or slot that is drawn in the diagram.

Anderson 9 bus network into PowerFactory One reason to employ a remote script is if you have multiple study cases using the same script code, but different input parameters.

Note that the name of the results file needs to be changed to eliminate spaces, e. You must first load the tutogial file into memory using the command: This document provides some detailed instructions on manipulating virtual instrument panel objects using the Python scripting language.

SetTitm and accessing its variables.
