Regulator Events

Regulator events are used to provide direct and indirect control of regulator structures e.g. weir crest levels, pump switching, pump speed etc.

In InfoWorks networks, regulator events can be used instead of Real Time Control (RTC), or to override RTC when directly controlling a regulator.

The events can also be used to provide output values for an RTC table when indirectly controlling a regulator.

Using Regulator Events instead of, or in conjunction with RTC can help in avoiding the creation of a large number of Scenarios or a large number of branched networks when editing controls.

To use a regulator event in a simulation, select the event in the Schedule Hydraulic Run View or SWMM Schedule Hydraulic Run View when scheduling a run.

Regulator event data can be viewed and edited on the Event Editor.

Note

Regulator events cannot be used in simulations in conjunction with Time Series Database objects.

Sub-Events and Profiles

Regulator events, like many other types of event, are divided into:

For more details on how InfoWorks ICM deals with sub-events and profiles, see the main Events topic.

Each column on the Event Editor grid represents a single control profile, and the object at which the profile is applied is shown in the column header.

There are three types of regulator profile:

Note that when a direct and indirect profile measure the same variable at the same time, then the direct profile will take priority.

In InfoWorks networks, a special value of -9999 may be used in a profile to indicate that the regulator should use RTC at a time within a sub-event. If the last value in the sub-event is set to -9999, RTC will be used from the end of the sub-event until the start of the next sub-event.

Direct and DirectStep profiles

Direct and DirectStep profiles can be used to model a regulator under manual control.

The values in the profile represent the measured values of the regulated variable and will replace RTC controls for the regulator if RTC is present.

To apply the profile to a regulator in the network, select Profile type of Direct of DirectStep and set Reference to the Object ID of the regulator in the event Profile Properties Dialog.

Indirect profiles

InfoWorks networks only.

Indirect profiles provide indirect control by providing a time series of measured values which are used in RTC Tables (of input type Time) to indirectly control one or more regulators.

To apply the profile to a RTC table, select Profile type of Indirect and set Reference to the name of the RTC Table in the event Profile Properties Dialog. The reference should take the form RegulatorID.TableName for tables defined in regulators in the RTC, or TableName for tables defined in the Global section of the RTC.
