Running DEW Applications

DEW provides many applications for system simulation and analysis.  These are grouped by field of discipline and in some cases allow for interdisciplinary dependencies, i.e. water flow from a pump station is dependent on electrical power to the pump.  The general process for running an application in DEW is outlined here, with application-specific details addressed in the section covering the particular application.  

1. Application Setup:
   
   The first step in running an application is to launch Setup for Analysis Execution from the Analysis menu.
   
   
   
   
    

1. In the Analyses Available window, Highlight the desired application with a single left click, as "Load Estimation" is shown above.  
   Note: A double left-click will add it to the Analyses Selected window, where "Power Flow" is the only application showing.  

2. Choose Edit Analysis Parameters to view or modify application-specific setup options, for the application highlighted in the Analyses Available window.  

3. Choose Select for Execution (or double left-click) to add selected application from the Analyses Available window to the Analyses Selected window.
   Note: If needed, use the Remove... buttons to remove one (highlighted analysis) or to clear ALL items from the Analyses Selected window.

4. Set Global Execution Parameters (common for all applications) to desired settings:

• Select On/Off status for execution progress, displayed in the Status area of main window

• Select On/Off status for component-level messaging

• Select On/Off status for beep notification of run completion

• Select On/Off status for run diagnostics (pop-up messages giving status at key break points)

• Input year (past, present, or future) for analysis occurrence

• Open dialog to select specific circuits for analysis

• Execute command to remove all current component messages from memory

• Open dialog to select available time points for analysis, dependent upon database setup

5. Choose OK to exit dialog, ready to run application(s) in the Selected Analyses window.
   
    

2. Setup for Display (of Output Variables):
   
   The next step to complete before running an application is Setup for Results Display, which can also be launched from the Analysis menu.  Here, users select the output variables they would like displayed from the analyses being run.   
   Note: If the run command is executed before the analysis has been setup for display, then the setup window will launch prior to execution.  
   
   
   
    

1. Selecting an application in the Applications window produces a list of the available results for that application in the Variables window.  Displayed above are results available from the Power Flow analysis.  
   Note: The complete variable list available for each analysis is described in the applicable guide for that application.  

2. If you would like to limit the results display to only certain phases, then deselect any Phase check box that you do not want displayed.  As above, only results for a variable's Phase A will be added to the display list.  

3. Highlight (single left click) a variable of interest and choose Add to List (or double-left click variable) to have those results added in the Display List window.  Shown above, we have added all phases of the "IMagA" variable and only Phase A of the "VMagKv" variable from the Power Flow application.  

4. Continue adding to the Display List until you have chosen all of the applications/variables that you want displayed from the analyses selected for execution.  
   Note: Results can only be displayed for analyses that have been selected for execution.  If you try to display a variable from an application that has not been run, then you will receive a "No Results for ... (application)" message in the status area of the main window when you attempt to display that result.  

5. Choose OK to exit dialog, ready to display the results showing in the Display List window.
    

3. Application Run:
   
   After completing the setup procedures for execution and display, you are ready to run analyses.  

1. From the tool bar in the main window, click on the Run icon , or select Run Analysis from the Analysis menu.  

2. The analyses will run, with messaging and user interactions dependent on application and settings.  
   
    

4. Displaying Application Results:
   
   Once the application has run, you are ready to display results.
   Note: Results are only displayed for components that have their Results-Display property setting ON.  Display properties can be viewed/edited from the [Display Position...] command button on the main component properties dialog or from the Tool bar, using the Schematic Control Panel menu or the Circuit Tools / [Control Cmp Display Info] submenu.

1. From the tool bar in the main window, click on the Display icon

2. The first result from those selected for display will appear in the drawing window as shown below, where a simple power flow analysis was run and the current (amperage) values "IMagA" for all three phases are displayed.
   
   Note:  The variable name and phase color legend are displayed in the status bar (bottom right).
    

3. Another single click on the Display icon will update the view with results for the next variable selected for display.  As shown below, we display Phase-A voltage (in kV) from our Power Flow analysis run.  
   
   Note: The variables display in the sequential order that they occur in the Display List window of the Setup for Display dialog, with the active display variable (i.e. "VMagKv") showing in the status bar, along with the displayed phase ("A").   

4. Continue to click the Display icon to show all of the analyses results selected for display.  Before the Display command restarts the results sequence, the main window will cycle to the view without any results showing and without any variable information in the status bar.

5. The selected results for display remain effective throughout the DEW session for the active file, so you can quickly determine effects from changing components/configuration on a given application.  However, you must execute the run command to incorporate any such change, before displaying updated results.  

6. Once you have completed your session, or are running another application, you will need to restart with the Setup for Analysis Execution.   
    

5. Plotting Application Results:
   
   For some application results, the user may choose to view output from the run graphically.

1. Generally, plotting is initialized by selecting the Plot icon from Tool Bar or the  Setup for Plotting item from Analysis menu.  

2. Either choice opens the DEW Plot Setup dialog, where user:   

1. Selects Application and output Variables (with Phases as applicable) for plot from the available listings.

2. Chooses Plot Type (i.e. Time vs. Distance) and define any custom user settings (i.e. Plot Options or Parameters).

3. Picks the Reference Component for defined plotting routine, using Pick Cmp command button.

4. Executes the plotting routine by choosing Plot command button.  

3. The output is then displayed in its own window, where user may view, print, export (as xml file) or modify available display settings.  See Plot Output for more details and sample output.
