DEFINING AND CONFIGURING A PROJECT

8.1.1 The Project Edit Dialogue

The project dialogue of 8.1.2 pops up when selecting Edit → Project. . . on the main menu or when right-clicking the project folder in the Data Manager and selecting Edit from the context sensitive menu.

The ’Basic Data’ page, allows the edition of basic project settings and the creation of new study cases and grids:

• Pressing the button at the ’Project Settings’ field opens a dialogue where the validity period of the project, the input units to be used within the project (unit system and the decimal prefixes for the adaptable element input dialogues within the project) and the calculation settings (the base apparent power and the minimal value of the resistances and conductances in p.u) are defined.

• Pressing theNew Grid button will create a new grid and will open the grid edit dialogue. A second dialogue will ask for the study case to which the new grid folder will be added. For additional information about creating a new grid please refer to Section 8.2(Creating New Grids).

• The New Study Case button will create a new study case and will open its dialogue. The new study case will not be activated automatically. For further information about creating study cases please refer to Chapter 11: Study Cases, Section 11.2(Creating and Using Study Cases).

• When a project is created, its settings (i.e.the result box definitions, the reports definitions, the flexible page selectors, etc.) are defined by the ’default settings’ from the system library. If these settings are changed, the changes are stored in the Settings folder of the project. The settings from another project or the original (default) ones can be taken by using the buttons Take from existing Project or Set to default in the ’Changed Settings’ field of the edit dialogue.

The settings can only be changed when a project is inactive.

• The name of the active study case is shown in the lower part of the dialogue window under the

’Active Study Case’ assignment, it’s edit dialogue can be opened by pressing the button.

Figure 8.1.2: The project dialogue

• Pressing the Contents button on the dialogue will open a new data browser displaying all the folders included in the current project directory.

The ’Sharing’ page of the dialogue allows the definition of the project sharing rules. This function is especially suitable when working in a multiple user database environment, further information is given in Chapter 18(Data Management).

The ’Derived Project’ page provides information when the project is a derived project of a master project.

The ’Storage’ page provides information about the stored data inside the project.

The ’Description’ page, like all object’s description pages is used to add user comments and the approval status.

8.1.2 The Project Overview Window

The Project Overview window is illustrated in figure8.1.3. It is a dockable window, displayed by default on the left side of the main application window between the main toolbar and the output window. It displays an overview of the project allowing the user to assess the state of the project at a glance and facilitating easy interaction with the project data. The window is docked by default, but can be undocked by the user and displayed as a floating window that can be placed both inside and outside of the main application window. If required, the window can be closed by the user. To close or reopen the window the user should deselect or select the option Window → Dock Output Window. . . from the main menu.

Only one window can be open at a time.

The following objects and information can be accessed via the project window.

• Study Cases

– Active Study Case – Inactive Study Cases – Current Study Time

• Operation Scenarios

– Active Scenario Schedulers – Active Scenarios

– Inactive Scenarios

• Variations

– Recording Expansion Stage

– List of active Variations with active Expansion Stages as children – List of inactive Variations with inactive Expansion Stages as children

• Grid/System Stages

– List of active Grids or System Stages – List of active Grids or System Stages

• Trigger

– Active triggers

Entries for active objects are displayed with bold text, entries for inactive objects (where currently no object is active, but inactive objects exist) are displayed as disabled/grey.

A context sensitive menu can be accessed by right clicking on each of the tree entries. The following actions are available for each of the entries:

• Change active item(s): Activate, Deactivate, Change active

In the Project Settings you can set up the Validity Period of the Project, the method used for Calculation of symmetrical components for untransposed lines, and other settings.

The Validity Period of the Project

PowerFactory 15 extends the idea of a model into the dimension of time. The Project may span a period of months or even years considering network expansions, planned outages and other system events.

The period of validity of a project specifies therefore the time span the network model, which is defined in the Project, is valid for.

The Validity Period is defined by Start Time and End Time of the Project (see Figure 8.1.2). The Study Case has got a Study Time, which has to be inside the Validity Period of the Project.

To specify the Validity Period of the Project:

• Open the Data Manager and browse for the Project folder object (IntPrj).

• Right click on it and select Edit from the context sensitive menu.

• On the Basic Data tab press the ’Project Settings’ Edit button ( ). The Project Settings dialogue will open.

• On the ’Validity Period’ page adjust the start and end time of the project.

• PressOK to accept the changes and close the window.

Advanced Calculation Parameters

• Auto slack assignment

This option has only an influence of the automatic slack assignment (e.g. if no machine is marked as "Reference Machine")

– Method 1: all the synchronous machines can be selected as "Slack" (Reference Machine);

– Method 2: a synchronous machine is not automatically selected as "Slack" if for that machine the option on load flow page: "Spinning if circuit-breaker is open" is disabled.

• Calculation of symmetrical components for untransposed lines

The selection of one of these methods defines how the sequence components of lines in Power-Factory will be calculated:

– Method 1: apply the 012 transformation (irrespective of line transposition). This is the stan-dard method used;

– Method 2: first calculate a symmetrical transposition for untransposed lines, and then apply the 012 transformation.
