Welcome to PSS/ADEPT 5

1.1 About the PSS/ADEPT Application

The Power System Simulator/Advanced Distribution Engineering Productivity Tool (PSS/ADEPT) software was developed for engineers and technical personnel who design and/or analyze elec-trical distribution systems. PSS/ADEPT enables you to graphically create, edit, and analyze power system models and diagrams.

PSS/ADEPT is available in stand-alone and network configurations for Microsoft® Windows 2000 and Windows XP. Compatibility with PSS/U (Power System Simulator for Utilization) is provided through raw data files and an associated Construction Dictionary. PSS/ADEPT is the next genera-tion of the PSS/U product line.

1.1.1 Application Capabilities

PSS/ADEPT offers a full spectrum of design and analysis capabilities. Using PSS/ADEPT, you can: • Create and modify power network models graphically.

• Perform engineering analyses using multiple sources and unlimited nodes. • Display the results of engineering analyses on the network diagram.

• Obtain output reports that display the results of a previously solved engineering analysis.

• Define and update single and multiple system component data via property sheets.

The Equipment List View

Within the Equipment List View (Figure 1-5), the Network tab provides a hierarchical display of each major type of network item – nodes, branches, and shunts. Additionally, there are different types of branches and shunt devices that may be specified in the network diagram:

• Branches may contain lines/cables, switches, transformers, and series capacitors. Branches may also contain protection equipment packs, which define protective devices.

• Shunt devices may contain capacitors, machines, static loads, MWh loads, harmonics injections, harmonic filters, and standard faults.

• Defaults contain the default properties for node, branch and shunt devices. Default properties are used when a new device is placed on the diagram.

(38)

Figure 1-5. Equipment List View

Each network item in the Equipment List View has its own icon that is the same as the symbol used to represent the item in the Diagram View. Notice the + and – symbols in front of each network item type. Click the + symbol to expand the tree display; and click the – symbol to collapse the tree dis-play. For example:

• Click the + symbol in front of Nodes to display a list of each individual horizontal/vertical/point node in the diagram. Click the – to collapse the view to its orig-inal state.

• Click the + symbol in front of Sources to display a list of individual sources. Click the – symbol in front of Sources to collapse the tree.

If an individual network item symbol is "grayed" in the tree hierarchy, the item is not in service. If there is no symbol in front of the item, it is not drawn on the diagram. This situation com-monly arises when there are nodes in a PSS/U raw data file with x- and y-coordinates at (0,0). The item will display in the Equipment List View as [ ], indicating an undrawn device. This item can be drawn by right-clicking on the item and selecting Draw Item(s) from the pop-up menu.

2. Right-click on Static Loads to position at the type level and display the Equipment List View’s pop-up menu (Figure 1-7). Here you can dock or hide the Equipment List View, sort the individual static load items, and toggle the display of the item node connections: FROM/TO for branches and node location for shunts, or device names. ("Grayed" menu options are not available at this level.) For example:

(41)

3. Expand the static load type level and right-click on first individual network item to dis-play the Equipment List View’s pop-up menu (Figure 1-8). Here you can dock or hide the Equipment List View, sort the individual items, toggle the display of the item node connections: FROM/TO for branches and node location for shunts, or device names, delete the item, zoom to the item on the diagram, and adjust the properties for the item. For example:

Figure 1-8. Individual Item Level, Equipment List View Pop-Up Menu

Docking, hiding, sorting, adjusting the PSS/ADEPT display, etc., are all described further in Chapter 2, Section 2.1.

A check mark in front of an option in the Equipment List View pop-up menu indicates that the option is active.

Although the Cut, Copy, and Paste operations affect both the Equipment List View and the Diagram View, these operations may only be performed from the Diagram View. Hence, these operations are not available in the Equipment List View pop-up menu.

The Results tab is used to set what results, if any, should be displayed on the diagram. For more information, refer to Chapter 4, Section 4.3.3.
