1. Introduction

1. Introduction
• The project object is allows the user to perform
advanced management tasks such as:
– Versioning, (Versions)
– Deriving, (Derived Projects)
– Comparing,
– Merging
– and Sharing.
• It simplify the work in multi-user environments while
minimizing the amount of data.

1. Introduction
Main Features:
– Network data stored in single or multi-user database
– Network Modeller incl. Single Diagrams and Block
Diagrams
– Network Variations for expansion planning
– Operation Scenarios for operational data
– Network Model Versioning
– Network Model Sharing in multi-user environment
– User accounts, user groups, access rights
– Compare and Merge Tool
– Change Tracking

1. Introduction
• PowerFactory allow use of the objects stored inside
them objects to recognize:
• The parts of the network model (grids and
expansion stages) to be consider for calculation.
• The calculations (and their settings) to be
performed over the selected parts of the network.
• The study time.
• The active variations.
• The active operation scenario.
• The calculation results to be stored for reporting.
• The graphics to be displayed during the study

Scenarios and
Expansion Stages

component ratings are considered

Operation Scenarios: different operative

• The Operation Scenario concept is useful to analyze the
network at different times during the day, week or year,
where changed loading conditions and different

Variations: Different topological configurations
e.g. Variations can be seen as expansion plans composed of different expansion stages, which are chronologically activated.

• Variations are objects that can store and implement the
changes which are expected on a network without
affecting the original model.
• The changes contained in an expansion stage can be
classified as:
• Changed parameters of network components;
• Additions; i.e. objects added to the network.
• Deletions; i.e. objects removed from the network

• To create a new variation, right-click on the Variations
folder ( ) in the data manager
• Select New -> Variation from the context-sensitive
menu.

A Version is a snapshot
of a project taken at a
certain point in time.

• Right-click the desired project folder in the right pane of
the Data Manager where the Version is to be created.
• Select New --> Version from the context-sensitive
menu.

• Define the version characteristics in the pops up
windows.

At certain stages of a system study, several users may wish to work
on the same project.

Internally only the data differences between the "Base Project"
and the "Derived Project" are stored in the database.

• A new derived project is created using the Data Manager
as follows:
• Right-click the desired project folder in the right pane of
the Data Manager where the Derived Project is to be
created.
• Select New --> Derived Project from the context-
sensitive menu.
• Select the source version of the base project from the
data browser that pops up. This will likely be the last
available version of a project in a public area, created by
the data administrator.
• Press OK.
