Single-Phase and Unbalanced 3-Phase Power Flow

The EasyPower Power Flow module now includes the ability to perform an unbalanced power flow analysis for systems that include 3-phase, single-phase, and DC equipment.

• The unbalanced power flow analysis considers all phases, neutral and ground.
• Supports display of results in multiple formats.

Power Flow Calculation Method

If your EasyPower license includes the power flow feature, you will see a new option to specify the Power Flow Calculation Method in Tools > System > Options. You can choose from Balanced or Unbalanced.

Power Flow Enhancements

In addition to the new single-phase and unbalanced 3-phase capabilities, the following power flow features are now available:

• Display of diverged power flow solutions to help with troubleshooting.
• Start an unlimited number of motors.
• Capacitor-assisted motor starting.
• Transformer ratings based on both ampere and kVA.
• Option to reinitialize the LTC starting point from nominal.

Power Flow Tab Display

The Power Flow tab now includes icons to display phase and sequence information.

Power Flow Options - Control Tab

The Power Flow Options - Control tab has additional settings for single-phase power flow solutions.

Power Flow Options - Text Output

The Power Flow Options - Text Output tab has a new Network Options selection.

Power Flow Options - One-line Output Tab

The Power Flow Options - One-line Output tab has new options to show results if the power flow solution does not converge, and enables you to specify bus voltage angle precision. The bus voltages can now be displayed in line-to-ground units.

Load Data Connection Information

The Load Data - Connection Information section of the dialog box now includes the ability to specify delta, wye, or wye-ground connections.

Enhanced Database View

The Database Browser and Database Report, now accessible in the main ribbon, include new functionality and a simplified default display of essential system information in a tabular format.

• Data can now be sorted by any parameter for improved organization such as grouping protective devices by their connected bus.
• A new filter feature provides the ability to focus on specific subsets of equipment such as buses below a certain voltage.
• More data fields have been added.
• Improvements have been made to the user interface, report configurations, the Find function, and more.

Database Browser and Report Icon

There is a new icon to open the Database Browser and Database Report from the ribbon. This is available in the Database Edit focus and all of the analysis focuses.

Note: Because the Database Browser and Database Report are now easier to access from the ribbon, we have removed those options from the File menu. In addition, the Hyperlinks report has been moved to the Database Browser.

Once you have opened the Database Browser or Database Report, you can switch between the two views. The same configuration settings are used for both.

Summary Page

The summary page displays all of the equipment in the database in tabs on the left side of the window, with total counts for each equipment type. The page displays the results of the selected equipment type.

The summary list on the left can be reordered using a custom configuration.

Note that the Equipment icon has been removed from the Database Browser as it is no longer needed.

Total Buses/Nodes

The total bus and node count has been moved from the summary to the File Properties dialog box, as shown below.

Equipment Detail

As you select a tab from the summary on the left, the spreadsheet on the right displays the details for the selected equipment.

Configuration

You can create custom configuration views. You can reorder where equipment appears in the summary list, select which columns you want to appear for each equipment type, and add or remove columns for each equipment type. Additionally, for each type of equipment, you can reorder the column order of the data being displayed.

This gives you the ability to see the equipment you want and the data you want displayed for that equipment in the order you want it displayed. See Database Browser and Report Configurations for more information.

Find Improvements

With the Database Browser in view, use Find to search for text in the browser spreadsheet.

This searches all the columns in the browser for the text you type. The program highlights cells that match the text as you type. The Find box also displays the number of matches found, and provides arrows you can click to advance forward or backward through the matching text.

Column Sorting

Each time you click on a column heading in the Database Browser, it rotates between ascending, descending, or default sort orders. An arrow appears at the top of the column to indicate the sort order.

Only one column can be sorted at a time.

Bookmarks

In the Database Report, there is now a Bookmarks pane you can use to quickly navigate to different equipment groups on the report.

An asterisk next to the equipment group name indicates that the same filtering and sorting that was used in the Database Browser is being used for the Database Report.

Harmonics - IEEE 519-2022 Compliance

The Harmonics reports are updated in accordance with the revised limits in the latest version of IEEE 519.

• Voltage distortion limits are now only considered for harmonic orders less than or equal to 50.
• Current distortion limits for harmonics 2, 4, and 6 are decreased while limits for even harmonics greater than 6 are increased.

Revit® 2023 Support

The Revit Integrator now supports importing BIM projects from the latest version of AutoDesk® Revit®. You can download the EasyPower Integrator app from the Autodesk App Store. The App Store will be updated with the latest version shortly after the EasyPower 11.0 release, so please verify the version prior to downloading.

Bug Fixes

The following issues have been addressed in this release:

Arc Flash

• Fixed an issue in adjustable frequency drives to use the correct FLA when using the Integrated method.
• Fixed an issue where in certain situations, the Integrated method was not displaying the worst-case arc flash boundary.
