Energy-saving measures in water supply and distribution systems can be realized in many ways,
00:09
from field testing and proper maintenance of equipment, to the use of optimal computer control.
00:15
The InfoWater Pro Scheduler can assist you in selecting cost-effective pumping policies
00:20
to reduce operational costs and provide more reliable operations.
00:25
To use the Scheduler properly, you need to set up controls and constraints—in effect, penalty costs.
00:32
The Scheduler can then determine the least-cost pump, valve, and pipe operation policies
00:38
to best meet the target hydraulic operational requirements of the system for a given time period, typically 24 hours.
00:45
To begin, double-click the desired project .aprx file to open ArcGIS Pro.
00:52
Once the project starts, in the InfoWater Pro ribbon, Project panel, click Initialize.
00:59
Run a standard simulation for the current scenario.
01:02
In the InfoWater Pro ribbon, Analysis panel, click Run to open the Run Manager.
01:09
Click Run to run the simulation and create an output for the current scenario.
01:14
Leave the Run Manager open.
01:17
Next, run an energy simulation for the current scenario.
01:21
Expand the Simulation Options drop-down and select ENERGY.
01:26
Click the ellipsis next to the drop-down to access the ENERGY Simulation Options.
01:31
Click the Energy tab.
01:55
Optionally, you can click the ellipsis next to the dropdown to view the pattern.
02:05
Click OK to close the Simulation Options window.
02:08
Click Run to start the simulation and create an output for the Energy simulation.
02:14
Close the Run Manager.
02:16
With the run complete, review the output of a pump.
02:21
In this case, from the Model Explorer, select P-140 and review the output.
02:26
Notice the additional output fields related to the Energy simulation.
02:31
You can also view an Energy summary table from the Report Manager.
02:36
To do so, from the ribbon, View panel, click Report Manager, then click New.
02:42
In the Output Report/Graph dialog box, click the Tabular Report tab, and then choose Energy Summary.
02:50
When you are finished, close the Report Manager.
02:53
You can now access the Scheduler app.
02:57
In the ribbon, Project panel, click Apps to open the App Manager.
03:02
Select Scheduler, and then click Run to open the Scheduler app.
03:09
In the Scheduler, click the View menu and select Input Data.
03:12
In the Control Group, you define the control groups to be used in the optimization analysis.
03:18
Each control group is identified as having one or more pumps, valves, and pipes.
03:24
The goal is to determine a single combination of control rules—start and stop times—for all pumps, valves,
03:30
and pipes within any particular group.
03:33
It is important to note that the Scheduler does not optimize set points;
03:38
you are only setting the on and off switches for the pumps within the simulation interval.
03:43
For each of the pump, valve, and pipe control groups, you can select existing databases or create new ones.
03:50
Click the DB Editor to view and edit the group information.
03:54
Once a table is populated as the Active Group, you can view or update the data as needed,
04:00
such as the maximum number of switches, start time, and duration.
04:05
Add a pump group to the Scheduler.
04:07
Under Control Group, select Pump, and then click New….
04:12
Name the new pump group.
04:14
For this example, type “PUMP_GROUP” in the field and then click OK.
04:20
This adds an Information Field to the Pump Information DB Table.
04:25
With the exception of the Pump IDs field, the values in the Active Group #1 table should automatically populate.
04:32
Select DB Edit to open the Pump Information DB Table.
04:36
Input the following values in the PUMP_GROUP column.
04:42
Save and Exit the DB Editor.
04:44
The Input Data for the Source Cost table is used to account for the cost of water from various sources.
04:51
This input data defines the charge per unit of volume leaving a tank or reservoir—for example, a treatment plant.
04:59
The Curve ID specifies how the source cost (Y in cost currency)
05:04
varies as a function of the total flow leaving the tank or reservoir (X in flow units).
05:10
The Scheduler allows the elements being optimized to function with certain operating conditions or penalties.
05:17
These can be set under Constraint and are essential for the Scheduler to perform successfully.
05:23
Constraints can be specified for each of the following categories:
05:27
Tank Level, Junction Pressure, Pipe Flow/Velocity, Pump Flow, Valve Flow, and Junction Water Age.
05:37
In each case, penalty costs are applied when the constraints that you specify are violated, such as the maximum flow value for a pump.
05:46
Keep in mind that specific constraints that you set in the Scheduler take priority over domain constraints.
05:53
To add each constraint, click Insert Rows… to properly populate each table.
05:59
Enter the following values for their respective constraint.
06:21
Finally, before running the Scheduler, click Options.
06:27
Here, you can review and set optimization options by specifying the data units,
06:32
penalty costs and weighting factors, convergence parameters (or termination criteria),
06:38
and advanced Genetic Algorithm or Particle Swarm Optimization options.
06:44
Depending on the algorithm you choose, you can access more options, but you usually do not have to change these settings.
06:51
You can also set the Output Report Location if you want to create a text file of the output report for a permanent record of the results.
06:60
For this example, enter the following Weighted Cost Factor values:
07:04
Set the Tank End Level Penalty to 100.
07:08
Set the Tank Target Level Penalty to 100.
07:11
Set the Tank Level Penalty to 100.
07:15
In the Termination Criteria, set the Maximum Trials to 20000.
07:21
In the Optimization Options, enable the PSO: Particle Swarm Optimization.
07:27
With the Input Data completely filled in, all required information is present for executing a Scheduler optimization run.
