Whereas the block definition could be seen as the design or model for a piece of equipment, the common model can be seen as a specific physical digsileng of the equipment item itself e. Details on Python installation you may find in PowerFactory user Manual. An example of a composite frame for a synchronous generator Figure 3.
Note that the name of the results file needs to be changed to eliminate spaces, e. The slots for the generator, governor, turbine and voltage controller now need to be filled. This example shows the application modal analysis with Power Factory to P. There are type objects in the library i. These input and output results files need to be specified. In such thtorial, an iterative, numerical initialisation routine can be used.
It can be seen as the design or blueprint for a piece of equipment e. We can use the linear search function to digsilentt the value of vw that will yield a value of pw closest to its initial value: Lastly, the script fills in the title block information. The following references are useful for the interested reader: Once we have finished creating these model definitions, we will have then defined complete blueprints for the hydro generation control system, i.
PowerFactory – DIgSILENT
This becomes an issue when exporting the model and importing it to different PowerFactory databases. This file is just for academic use 29kB. Common models are grid elements that belong in the grid.
The variables to be initialised should be configured with either fixed tutlrial initial conditions or estimates.
Refer to Chapters 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. The following list of calculation command objects are available: Construct a composite frame showing how the slots are interconnected 3. Two model definitions digsikent 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.
It is important to know that accessing data from tuhorial specific object and variable in the Results file hinges on knowing the relevant column index. For more information please refer to Navigating Project Folders in section 3. Step response of integrator 4. An error will be thrown if the model equations have undefined variables or signals e. Some of the useful topological search functions: Consider the hydroelectric generation system shown in Figure 2.
This configuration is reflected in Figure 2. Enter the email address you signed up with and digsjlent email you a reset link. Please make a reasonable use of this documents. Creating and Using Study Cases P. Returns NULL if the cubicle does not exist. Power System Stability and Control. It stores only the file path of the script and not the code itself.
Wind Turbine Block Let us revisit the wind turbine example in Section 4. Objects cannot be created into a VI panel object while the graphic is open.
General Software Information
If you had locally defined scripts, then you would need to change the code in every single local Python object individually.
To illustrate how to use the linear search function, we can apply it to the wind turbine example above.
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. The input signal g should be initialised such that the model equations yield pt at the output more on block initialisation later. GetAll Without setting any of the options, the above snippet is equivalent to calling oCub.
Manually creating local title 6. The documents here are free to be used in all ways. A common model inherits the block diagram of the linked model definition, but has its own local parameter settings.
