Controlling Regulators using TVD Connectors (SWMM)

TSDB functionality is only available if the TSDB option is enabled on your licence.

TVD Connectors can be used to provide a link between data streams in a Time Series Database (TSDB) and a Regulator. The data stream profiles are used as an input to a regulator object to control the regulator.

Note: TVD connectors and time series databases are not currently used in cloud simulations.

To use TVD connectors to control the status of a regulator:

• Ensure that the TVD connector ID is the same as the name of the time series in the SWMM Control Rule.
• Set the Input A units type to FRAC. The Input B units type, Input C units type and Output units fields will automatically be set to FRAC.
• Set Input A to the ID of a data stream in the applicable Time Series Database or to another TVD connector. Set the Input B and Input C if required.
• Set Connection object type to the applicable regulator object - pump, orifice, outlet or weir.

The values provided by the TSDB data streams will then be used to control the regulator.

Regulator output units

The output units required for different regulator types are listed below:

Regulator type	Regulated variable	Unit type
Pump	On/off status, and pump speed	Frac - Fraction
Orifice	Opening size	Frac - Fraction
Weir	Crest level	Frac - Fraction
Outlet	Flow	Frac - Fraction
