To design and manufacture an electrical control system to monitor
and control the flow and level of a tidal moat. The system will
include a SCADA (Supervisory Control And Data Acquisition) package.
Project Background
The level of water in the moat is dependent on the inflows from
a local tributary river and stream and by the tide. The existing
system utilises a manually operated gate.
Solution
The control panel is situated in a purpose built building local
to the gate. Remote flow monitors are installed on both the tributary
river and stream. Up to date flow information is sent via modem
to the control room where it is processed and transferred to the
SCADA package.
Various transducers measure the actual water levels of both the
Moat and Estuary along with the current position of the gate. This
analogue information is converted into digital form and fed into
the SCADA package.
A tidal prediction program keeps the SCADA package constantly updated
with the predicted height of the tide and the high and low tide
information. The SCADA package uses all of the above data to decide
the position of the gate ensuring the level of water in the Moat
is always at the required height.
