InfoSurge Pro allows you to create hydraulic transients by providing a curve which will alter pump and valve operations,
00:10
as well as junction demand changes.
00:13
You can then compare the simulation results from different operational conditions.
00:17
In this example, you create transients from pump startup events using the Pump Speed Change option.
00:24
To begin, double-click the desired project .aprx file to open ArcGIS Pro.
00:30
Once the project starts, click the InfoWater Pro tab to open the InfoWater Pro ribbon.
00:36
In the Project panel, click Initialize.
00:40
First, a curve supplying the time at which a pump will start up must be made or selected.
00:45
With the Select tool enabled, in the map, select pump 9_PUMP.
00:51
Then, from the Model Explorer window, click the Pump Operation Change button.
00:56
In the Speed/Wicket Gate Change Data dialog, set the disturbance type to “0: Speed”.
01:02
Then, next to the Speed Curve drop-down, click the Browse (…) button to open the Curve dialog.
01:08
In the dialog, click New.
01:11
Enter a curve ID of “CUR3, Pump Speed Up”, and then click OK.
01:16
Now, click the Set Rows button.
01:19
Enter a value of 3.
01:22
Enter the following values by assigning each X-axis value in numerical order, followed by values in the Y-axis column.
01:30
The X values correspond with time in seconds, and the Y values correspond with pump speed as a decimal (0 = 0% and 1 = 100%).
01:41
In the X column, enter: 0.00 in row 1, 2.00 in row 2, 3.00 in row 3.
01:52
In the Y column, enter: 0.00 in row 1, 0.00 in row 2, 1.00 in row 3.
02:04
Note that the curve updates visually in the graph view, and indicates that after two seconds,
02:09
the pump speed will increase from zero to full speed within one second.
02:13
Click OK to close the Curve dialog, and then Update in the remaining dialog to close the window and save the settings.
02:20
Next, set the pump surge data to select features to be modelled with the pump during a surge simulation.
02:26
From the Model Explorer, click the Pump Surge Data button to open the Pump/Turbine Surge Data dialog.
02:33
Here, make sure the Check Valve Installed option is enabled.
02:37
This will protect the pump from reverse flow entering.
02:40
Enter a check valve (CV) opening and closing time of 0.01 seconds.
02:46
Before continuing, make sure the Non-Reopen CV option is not enabled.
02:51
Since the check valve is closed before the pump starts,
02:55
if the non-reopen option is enabled, it will close the pump permanently,
02:59
even though the pump builds up enough head to open the check valve.
03:03
Click Update to close the dialog and save the settings.
03:07
You are now ready to run a surge simulation.
03:10
From the ribbon, InfoWater Pro tab, Analysis panel, click Run Manager.
03:16
In the Run Manager dialog, click the Run button, and then OK to close the dialog when the run is complete.
03:23
From the ribbon, InfoWater Pro tab, View panel, click Report Manager.
03:29
In the Report Manager dialog, click the New button to open the Output Report/Graph dialog.
03:36
From the Available Output Sources, select *Active*.Surge.
03:41
From the Graph Report tab, select Surge Node Graph, and then click Open.
03:47
Now, select Junction 10 to view its pressure profile.
03:51
Note that Junction 10 has a pressure spike at the time of pump startup identified in the speed curve.
03:56
Close the Report Manager.
03:59
Now, set the pump without a check valve.
04:02
Again, select pump 9_PUMP.
04:05
Then, click the Pump Surge Data button.
04:08
In the Pump/Turbine Surge Data dialog, disable the Check Valve Installed option.
04:13
Then, click Update.
04:15
Reopen the Run Manager.
04:17
Click the Run button, then OK to close the dialog.
04:23
Then, reopen the Report Manager and pick Refresh All to refresh the output for Junction 10 after the latest run.
04:30
Note that there is no transient because you disabled the Check Valve Installed option.
04:35
Close the dialog.
04:38
Next, use a lower pump speed to see how it impacts the creation of transient events.
04:44
From the map, select pump 9_PUMP, and again, open the Pump Surge Data dialog.
04:51
This time, enable the Check Valve Installed option.
04:54
Click Update to close the dialog and save the settings.
04:58
Then, from the Model Explorer, click the Pump Operation Change button to open the Speed / Wicket Gate Change Data dialog.
05:06
Next to the Speed Curve drop-down, click Browse (…) to open the Curve dialog.
05:11
From the CUR3 table, Y-column, change the cell in the third row to 0.50.
05:18
Note that the graph now indicates the pump will ramp up to half its full speed within one second after startup.
05:24
Click OK, and then Update.
05:28
To run the simulation again and review results, open the Run Manager, rerun the surge analysis, and then click OK to close the dialog.
05:38
Reopen the Report Manager and refresh the output for Junction 10 once more.
05:43
As you can see in the graph, a surge event is not present in the network.
05:48
Now, perform another run using a longer pump speed change operation time.
05:53
Select pump 9_PUMP again.
05:56
Click the Pump Operation Change button.
05:59
In the Speed / Wicket Gate Change Data dialog, next to the Speed Curve drop-down, click Browse (…) to open the Curve dialog.
06:07
With the CUR3 curve ID selected, in the Y-column, change the value in the third row to 1.00.
06:15
In the X-column, change the value in the third row to 12.00.
06:21
The graph updates to show that the pump speed will increase from 0 to full speed within 10 seconds.
06:27
Click OK, and then Update in the remaining dialog.
06:32
Reopen the Run Manager and rerun the surge analysis.
06:36
When the run is complete, click OK to close the dialog.
06:40
Reopen the Report Manager and in the dialog, refresh the output data.
06:45
Note that this does still produce a transient event,
06:48
however it is reduced from the previous results by greatly increasing the time it takes the pump to fully start up.
06:55
Close the Report Manager.

InfoSurge Pro allows for creating hydraulic transients by providing a curve which will alter pump and valve operations, as well as junction demand changes. This example compares simulation results from different operational conditions.
In the table, enter the following values in the X-axis column (time in seconds):
Enter the following values in the Y-axis column (pump speed as a decimal: 0 = 0% and 1 = 100%):
Note that the curve updates visually in the graph view, and indicates that after two seconds, the pump speed will increase from zero to full speed within the next one second.
Next, set the pump surge data to select features to be modelled with the pump during a surge simulation:
This protects the pump from reverse flow entering.
Since the check valve is closed before the pump starts, if the non-reopen option is enabled, it will close the pump permanently, even though the pump builds up enough head to open the check valve.
A surge simulation can now be run:
Junction 10 has a pressure spike at the time of pump startup identified in the speed curve.
Now, set the pump without a check valve:
Note that there is no transient with the Check Valve Installed option disabled.
Next, use a lower pump speed to see how it impacts the creation of transient events:
The graph now shows the pump ramping up to half its full speed within one second after startup.
Again, the pressure profile for Junction 10 appears as a straight line, with no surge event present in the network.
Finally, perform another run using a longer pump speed change operation time:
The graph updates to show that the pump speed will increase from 0 to full speed within 10 seconds.
Note that while a transient event is produced, it was reduced from the previous results by greatly increasing the time it takes the pump to fully start up.
