Basic Concepts
• All data is stored in a database.
• The network topology is also presented graphically.
• Two ways of accessing data:
– Via the graphical user interface
– Via the data manager

The PowerFactory Project
• A Project is the complete set of data:
- Network Models & Diagrams
- Demand/Generation Patterns
- Type and Operational Libraries
- Calculation Commands (Load Flow, Short Circuit, Contingency, etc.)
- Results, etc.
• In a project, data is organized in a set of folders (workbook structure)

Equipment Types
A Type holds the essential electrical information for each
class of component as usually provided in manufacturer´s
datasheets.
E.g. the cable type data :
• impedance values per length
• rated voltage and current, …
The library can contain sub-folders for each class.

6. 6
DIgSILENT PowerFactory Training „Load Flow and Short Circuit Calculation“ 11
The Operational Library contains following data
that can be applied to elements in the network
data:
• Circuit-Breaker Ratings
• Thermal Ratings
• Mvar Limits Curves
• Outages
• Demand Transfer
• Running Arrangements (RA)
• Faults: Fault Cases and Fault Groups

Network Model
The network model contains all electrical and graphical
information.
The model can be divided into:
• Network Diagrams: Overview, Single Line and
Substation Diagrams of all networks contained in
the project.
• Network Data: network components, switches,
topology, controller models, etc.
• Network Variations: e.g. reinforcements, new lines
or stations.
• Additional data like: Areas, Zones, Feeders,
Routes, Circuits, Paths, Boundaries, Virtual
Power Plants, Owners, Operators

Network Diagram: Working Modes
„Freeze“ Mode:
Entering and Changing Data, e.g. Switching or Changing of Loads (P,
Q)
No Graphical Changes possible
Changing of Result Box Formats
Graphic Mode:
Changing the Graphical Representation, e.g. Moving, Rotating,
Deleting of Elements, Changing the Size of Busbars / Terminals
Re-Connect Elements
Changing Position, Size and Orientation of Text and Result Boxes

Network Diagram: Handling
• Double Click on Symbol Opens Entering Dialogue
• Double Click on Switch Opens / Closes Switch
• Keyboard Shortcuts:
- „Shift“ while Moving „Ortho“ (moves only in horizontal or vertical direction)
- „Ctrl“ while Selecting -> Multiple Selection of several elements
- „Ctrl“ while Drawing Loads/Generators … -> 180° Rotation
- „Ctrl“while Drawing Loads/Generators Busbars/Terminals -> 90° Rotation
- „Ctrl“ + „C“ Copy marked Object
- „Ctrl“ + „V“ Paste copied Object (Graphic + Data)

Project Structure
• Study Cases
DIgSILENT PowerFactory Training „Load Flow and Short Circuit Calculation“ 22
Study Cases
• The Study Case specifies the grids, operation scenarios,
variations and calculation options to use for a study.
• Therefore, the study case holds:
– Links to active Grids, Operation Scenarios and Variations
– Study Time
– Calculation command definitions (Load-flow settings, etc.)
– Results of calculations
– Outage definitions for contingency analysis
– Graphical settings
(Plots; Visibility of Diagrams, Frames, and Blockdefinitions)
– etc.
• A concept of study case allows the user to reproduce results.

Project overview window
• The project overview window helps to keep the overview of the
project
• It is listed
– Study Cases
– Grids

Data Management

13. 13
DIgSILENT PowerFactory Training „Load Flow and Short Circuit Calculation“ 25
Undo Functionality
• All changes are internally recorded by a “time stamp”
in a project “history”.
• The Undo function can go back in the project history.
• Undo includes all data changing
(e.g. done inside the Data Manager)
• The history is cleared upon project deactivation.
• Changes can be:
– Deleting, changing, adding elements
– Graphical changes
– Modifications of parameter values
– Multiple simultaneous changes will be recorded as one change
– …

Tracking Changes in Object Data
Last Modified information:
• Shows a time stamp, when the object has been touched the last time.
• The user who is responsible for the change is shown.
Information allows:
• Check when/if object has been changed.
• Whom to ask.
Important: ANY change is considered!
