Real Time Control
Real time control (RTC) elements such as regulators, bendable weirs,
and telemetry-controlled pumps have been part of xpswmm since Version
2. This powerful add-on module extends the existing depth-only RTC to
a comprehensive management and design tool.
Its sensors can include velocity, flow and water levels and depths at
nodes, conduits, pumps, orifices, and weirs. The values of the sensors
can be compared with each other using typical Boolean logic and mathematical
operators. For example, a control can be activated if the water level
in location A is greater than location B by 2.3 feet.
Some of the parameters that can be modified include: flow, roughness,
diameter, water depths, pump on/off levels, well volume and speed factor,
weir crest and surface
elevation, discharge coefficient and length, and orifice area
coefficient.
Other control properties include Start and Stop
time of the control, ramp times and even the description of full PID
control.
