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 whileminimizing the amount of data.

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

2. Operation Scenarios and Expansion Stages• Variations are objects that can store and implement the
changes which are expected on a network withoutaffecting the original model.
• The changes contained in an expansion stage can beclassified as:
• Changed parameters of network components;• Additions; i.e. objects added to the network.• Deletions; i.e. objects removed from the network

4. Base Project, Versions and Derived Projects• 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 becreated.
• Select New --> Derived Project from the context-sensitive menu.
• Select the source version of the base project from thedata browser that pops up. This will likely be the lastavailable version of a project in a public area, created bythe data administrator.
• Press OK.
